Good Dog: Behavior & Training
More than just noise
March 7 2013
A friend suggested that one of the reasons we love dogs so much is that they can’t talk back. But I wonder whether that’s true. Sure, a dog won’t tell you, “You really shouldn’t have that second cookie,” but does that mean dogs are not talking back?
Dogs are anything but mute, and while we usually focus on wagging tails and beguiling eyes, vocalizations—among them, barks and growls—provide us with another window into dogs’ everyday experiences.
Social species are known to be much noisier than animals who lead solitary lives. Snow leopards roam the mountains of central Asia in near silence, but groups of monkeys do a lot of highvolume chattering. So, given that dogs and their wild progenitor, the wolf, are über-social, it’s no surprise that both produce a wide range of vocalizations: they bark, whine, whimper, howl, huff, growl, yelp and yip (among other nuanced sounds). From the earliest moments of their lives, dogs and their canid relatives produce tonal yelps and whines, and atonal barks and grunts appear in the fi rst few weeks of life in conjunction with the onset of social behavior.
There’s a big difference between the bark of an adult dog and that of an adult wolf, however. Dogs seem to play every instrument in the orchestra, hitting the highs of the flute and the lows of the tuba, sometimes with the duration of a Wagnerian opera. Plus, there seems to be no context in which a dog won’t bark: They bark when alone and with other dogs. Some bark before, during and even after a ball is thrown. A car goes by or the doorbell rings and barking ensues. In contrast, wolves bark less frequently and in fewer contexts, primarily for warning or defense.
Meanings Behind the Message
That being said, research that has been conducted on the subject is incredibly insightful. Take growls, which, it has been shown, dogs use to accurately judge another dog’s size. How in the world do we know that? Tamás Faragó, PhD, and his colleagues at the Family Dog Project at Eötvös Loránd University in Budapest (familydogproject.elte.hu) presented dogs with two images of the same dog: one was true to size and another was 30 percent larger or smaller. Dogs then listened to a pre-recorded growl, and most dogs looked at the image of the full-size dog rather than the altered image.
Growls appear to be meaningful in other ways as well. In another study, Faragó and his colleagues used some clever trickery to explore how dogs respond to growls recorded in different situations. In an apparently empty room, a dog was allowed to approach a bone. Unbeknownst to the dog, there was a speaker hidden behind the bone, and as the dog approached, the sound of a “play growl,” a “stranger-approaching” growl or a “food-guarding” growl was transmitted through it. Dogs were likely to take the bone when hearing the “stranger-approaching” or “play” growl, but the food-guarding “my bone” growl deterred them. Even though the foodguarding and stranger-approaching growls sound quite similar (at least, to our ears), they prompted different behavior.
Many studies investigating vocalizations are based on prerecorded samples, but it is important to remember that vocalizations and visual signals usually go hand-in-hand. In the strangerapproaching context, dogs growled with closed mouths, whereas in fooddefense situations, they showed their teeth and pulled back their lips.
While we tend to take notice when we hear a growl, we often dismiss barking as meaningless noise, as though it is simply an item on a dog’s daily checklist: “Take a walk, have breakfast, bark.” Before the turn of the century, that was the prevailing view among researchers and theorists. At most, barking was thought to result from social facilitation— one dog barking prompts other dogs to bark—or maybe attentionseeking, or even rivalry or defense.
Only recently have researchers begun to investigate whether barks produced in different contexts vary in their acoustic parameters (such as tone and pitch). Scientists theorized that if— like growls—barks displayed consistent differences, they might have a more specific communicative function, perhaps even be associated with a dog’s internal motivational or emotional state. For example, some barks might convey aggression while others might convey friendliness.
In one early study, Sophia Yin, DVM, MS, recorded a variety of breeds barking in response to different situations: a stranger ringing the doorbell (“disturbance barks”), separated from an owner (“isolation barks”) and play. Yin found that the barks did indeed have different acoustic properties. Disturbance barks were harsher and lower in pitch with little amplitude modulation, while isolation and play barks were pitched higher and had greater tonal and higher frequency and a wider range of amplitude modulation. More recent studies confirm that dog barks follow particular patterns. For example, a dog barking at a stranger sounds very different from a dog barking before going on a walk. But do these vocalizations carry meaning? They do for dogs. When dogs in one study listened to barks recorded in a new context or from a new dog, they gave more attention to the unfamiliar bark. This suggests that dogs can detect that some barks are different from others, though scientists are still exploring ways to determine how exactly they perceive and process that information. Humans, too, can decipher barks. Whether or not they’re experienced with dogs, people are quite good at classifying barks into their appropriate contexts and attributing them to perceived emotional states. After listening to randomly played recordings, people describe isolation barks as full of despair, while barks from a play session are said to be happy. Our ability to do this starts early; by age 10, children are able to assign different-sounding barks to the correct context. Today, we can distinguish the acoustic properties of certain barks so accurately that we’re able to program computers to categorize them (which confirms that computers will one day take over the earth; personally, I hope Ryan Gosling will be there to save us).
Recognizing the Patterns
A recent publication by Kathryn Lord, PhD, offers an additional take on why dogs bark. She and colleague Ray Coppinger, PhD, investigated the contexts in which other species use barklike sounds: “When other species emit their version of a bark, they are usually in some sort of conf licting situation. For example, an animal is at a nest or den and observes some sort of threat. Customarily, the animal would run, but because of its situation, it can’t, so it barks. We think [that] when dogs bark, they are making these sounds in association with an alert or an internal motivational state of conflict.”
In a sense, Lord and Coppinger argue that “conflicted” should be dogs’ middle name. They suggest that dogs bark in so many different situations because they often find themselves conflicted: they are in the house and want to go out, they are out and want to come in. And it may be that, through the process of domestication itself, dogs have become more prone to put themselves in these sorts of situations. In comparison with wolves, dogs have a substantially decreased f light distance; something can easily get too close before the dog feels conf licted about how to respond.
Udell suggests that barking doesn’t have to be whittled down to one simple explanation. “If you look at communication and vocalizations in a wide range of species, it usually isn’t about one thing. Chickadees have ‘alert’ calls, but they also have songs, and the songs themselves can mean different things in different contexts. I think the same could hold true for dogs.”
But genes aren’t everything. As Susan Friedman, PhD, a pioneer in the application of applied behavior analysis to captive and companion animals and a psychology professor at Utah State University, explains, “While Shih Tzus as a group tend to display less barking than Miniature Poodles, that doesn’t mean barking in Miniature Poodles is impervious to change. And I’ve certainly known individual Miniature Poodles who are quiet and individual Shih Tzus who are barky, both based on their current situations. The individual always bests any generalization.”
Dr. Yin’s study of dog barks concurs. Even within breeds, she found variations in who barked and when. Rudy and Siggy, 11-year-old German Shorthaired Pointers, both barked in the disturbance context, but when alone, Rudy did not bark and Siggy had lots to say.
The effects of the social environment on dog behavior can be important because sometimes, dogs just go with the flow. On The Bark’s Facebook page, Bev Morey of Kansas commented, “After attending day care each afternoon, my Weimaraner now barks at anything and everything. So annoying.”
“So annoying” is one of the challenges of barking. While all vocalizations, including barking, are generally seen as normal elements of dog behavior, barking is one of dogs’ less-appreciated attributes. According to Laura Monaco Torelli, CPDT-KA, KPA CTP, director of training at Animal Behavior Training Concepts in Chicago, “Barking can be especially challenging for those in urban settings, as they live in close quarters with neighbors.” Owners of barking dogs might receive dirty looks or formal complaints from neighbors, and enough complaints can lead to eviction.
Though dogs bark for any reason under the sun, barking is a construct of context, genes and environment, and so is flexible. For example, feral dogs are much less noisy than their counterparts who play with toys, sleep in beds and go to obedience class.
Friedman explains. “For dogs, barking is a functional behavior, meaning it is maintained, increased or decreased due to consequences. Once this is [understood], it opens the door to changing the duration, intensity and frequency of the behavior by changing the consequences.” In other words, dogs can learn to be quieter.
However, perfect quiet is probably unrealistic. Owners can’t always control the stimuli that prompt barking, especially if they’re not home 24/7. Moreover, barking that has been solidified and maintained over time through intermittent reinforcement has a lot of staying power. “It seems that owners unintentionally reinforce the barks produced when a dog is around food or toys, and these become the begging barks of that dog,” says Faragó.
Monaco Torelli agrees. “If a dog learns that the noise in the hallway goes away when he barks, barking becomes an effective behavior. Barking is followed by the consequence of the noise in the hallway stopping.”
Owners should focus not on eliminating barking altogether, but on reducing it to levels they find appropriate and livable. When she meets with clients to discuss their dogs’ barking issues, Monaco Torelli asks questions such as, “How many barks is okay? What’s excessive to you?” This, she says, gives the trainer a good starting point from which to develop a plan to teach the client how to reshape a dog’s barking behavior. Trainers and owners discuss acceptable barking, and then implement techniques to achieve desired levels in each context.
Friedman shares the way she manages her own dog’s barking: “We live in the country, and when we let the dogs out, they bark at the deer for a number of seconds. Then we say, ‘That’s enough, thank you,’ and they are quiet and we praise them.” She adds, “It’s a [mistake] to think that barking is the problem. The real problem is that dogs don’t stop barking when we ask.”
So-called “quick fixes” can make barking worse, particularly if the underlying reason for the behavior isn’t addressed. “Putting an anti-bark collar on a fearful dog is unlikely to decrease barking if the consequence [shock or spray] increases the dog’s fear. If the fear increases, barking could as well,” explains Marylandbased Mary Huntsberry, MA, ACAAB.
Strategies for Change
Barking can be managed and modified, so if you want to influence your dog’s vocal style, it helps to start early and be observant. Teaching dogs the boundaries of acceptable vocalizations from an early age will pay off for everyone; when dogs are young, barking might be cute, but as they age, the cute factor tends to wear off. If the behavior is already in place, there are ways to alter it, Huntsberry observes. “It helps to do a functional analysis. During an extensive interview, I identify what happens immediately before (antecedent) and after (consequence) the unwanted behavior so I can identify the trigger and what maintains it.”
Monaco Torelli focuses her attention on the dog-human relationship. “When owners are frustrated by their dog’s behavior, we show them some immediate training goals and success points so they see that their dog can do what they want them to be doing, instead of what they don’t want them to do. This helps them rebuild their bond with their dog.”
The takeaway message is that barking is a nuanced and flexible behavior, and relationships can grow by paying attention to what your dog’s vocalizations mean. And if you’re on a post-holiday diet and want to train your dog to bark incessantly whenever you make a move for another slice of cake, well, that’s just good teamwork.
Good Dog: Studies & Research
December 26 2012
“This is not your food! Don’t even think about eating it. This … is … not … your … food.” What do our words mean to dogs? Not that I’m about to stop speaking to dogs anytime soon, but I do wonder what my daily utterances signify to Millie, Piper, Upton and Finnegan, the dogs I converse with on a regular basis. Do I sound like a cross between Charlie Brown’s teacher and Gary Larson’s “What Dogs Hear” cartoon? Are we on the same page, or even in the same book?
I set out on a quest to explore dogs and their understanding of human language. What do we think dogs understand? A lot, according to a study by Péter Pongrácz and his colleagues at the Family Dog Project in Budapest. Thirty-seven owners provided a list of 430 different utterances that they thought their dogs knew, with each owner providing an average of 30 phrases.
Enter Rico, Chaser, Sofia, Bailey, Paddy and Betsy, companion dogs celebrated for their panache for human language. The news media hails them as “super smart,” and after meeting Chaser, astrophysicist Neil deGrasse Tyson exclaimed, “Who would have thought that animals are capable of this much display of intellect?”
So what are these dogs doing with words?
Seven years later, Chaser, a Border Collie in South Carolina, took the gold medal when Alliston Reid and John Pilley of Wofford College reported that Chaser knew the distinct names of 1,022 objects — more than 800 cloth animals, 116 balls, 26 Frisbees and 100 plastic items. Chaser knows that “Uncle Fuzz” is different from “Wise Owl,” who is certainly different from “Merlin.” This is not merely a story about Border Collies, however. Researchers recently related that Bailey, a 12-year-old Yorkshire Terrier, knows the names of about 120 toys.
Chaser and Rico also win praise for their ability to learn and retain the names of new objects. When presented with a group of toys, all of which were familiar except one, the dogs could retrieve the unknown toy when asked to fetch using an unfamiliar word. In essence, the dogs were pairing a novel object with an unfamiliar name after a single association and then remembering the name of that new object in subsequent trials. In children, this is called “fast mapping,” and it was thought to be uniquely human. Pilley notes, “This research shows that this understanding occurs on a single trial. However, Chaser needed addition rehearsal in order to transfer this understanding or learning into long-term memory.”
“That’s just training,” you might say, but this suggests that some dogs show a cognitively advanced skill where actions are understood as independent from objects. Reid and Pilley found that Chaser does not interpret “fetch sock” as one single word, like “fetchsock.” Instead, she can perform a number of different actions flexibly toward a number of different objects. Daniela Ramos, a veterinary behaviorist in São Paulo, discovered that a mutt named Sofia could also differentiate object names from action commands, suggesting these dogs attend to the individual meaning of each word.
This all seems quite extraordinary, but nothing comes free of controversy. Do dogs like Chaser and Sofia use and understand language the same way humans do, or are they merely welltrained? For example, some researchers are not certain that dogs actually “fast map”; dogs might be doing something that simply looks like “fast mapping” from the outside. Regardless, it does seem as though these dogs have a conception of objects and actions. Patricia McConnell, PhD, Certified Applied Animal Behaviorist and beloved Bark columnist, agrees. “Understanding requires that we share the same reference — that we have the same construct of an object or an action. For some dogs, it seems like they do.” Pilley concurs. “When an object, such as a toy, is held before Chaser and a verbal label is given to that object, Chaser understands that the verbal label refers to that object.”
In her book Inside of a Dog, Alexandra Horowitz reminds us that even if these are the only dogs in the world capable of using words this way, it allows us to see that a “dog’s cognitive equipment is good enough to understand language in the right context.” This body of research indicates what is possible, not necessarily what most dogs do every day.
Who Are You Living With?
Like Rocky Balboa preparing for his climactic showdown, these dogs are highly motivated. Fischer notes, “Rico was eager and hard working. You’d have to tell him, ‘That’s enough. Get something to drink. Take a rest.’” Chaser is similar, says Pilley. “She has two states—highly, highly active and recuperating and resting.”
Denise Fenzi, a professional dog trainer from Woodside, Calif., who specializes in a variety of dog sports, reminds us that this type of motivation is not necessarily the norm. “Not all dogs share this attention to words. Even in my dogs [all of whom are the same breed], there is a huge difference in ability to verbally process. I didn’t train them differently. It’s just easier for one to quickly get words.”
What dogs are able to do with language could also be explained by their tutelage. If dogs don’t learn to attach a variety of different actions to a variety of objects, it might be harder for them in the long run to be flexible with human language. Susanne Grassmann, a developmental psychologist and psycholinguist at the University of Groningen in the Netherlands explains, “Chaser was trained to do different things with different objects, and she differentiates between what is the object label and what is the action command, meaning what to do with that object.”
Ramos notes that Sofia’s relationship with certain objects was a bit different. “Throughout the training, we always paired ‘stick’ with ‘point.’ As a result, it was difficult for her to perform any other action toward the stick beside ‘point.’ If we had trained her ‘stick: sit,’ ‘stick: point’ and ‘stick: fetch,’ she would have learned that multiple actions can be directed toward the stick, and her response would probably be different. For example, when presented with a novel object, such as a toy bear, she could direct a number of different actions toward the bear, but there was a reluctance to change her action towards the stick, which could have to do with the rigidity of training.”
And even if you do explicitly teach that different words have different meanings, it can be challenging. Ramos found that learning the names of objects is not always easy for dogs. “It was hard for Sofia to learn to discriminate the names of her first two objects, but after the initial discrimination, it was like she learned to learn. It became easier,” recalls Ramos.
“Because this type of learning can be challenging, service dogs [who have little margin for error] are taught a limited, but instrumental, set of words,” explains Kate Schroer-Shepord, a qualified guide dog instructor at Guiding Eyes for the Blind in Yorktown Heights, N.Y.
Pilley found that dogs’ success at object learning depended upon the training method used. “When we put two objects on the floor and asked dogs to retrieve each object by name, they couldn’t do it; simultaneous discrimination wasn’t working. Instead, Chaser was able to learn the names of objects through successive discrimination. She would play with one object in each training session, and through play, the object assumed value. We’d name the object, hide it and ask her to find it. Discrimination testing between the names of different objects occurred later.”
Words or Melody?
Dogs derive an enormous amount of information from contextual cues, particularly our body movements as well as tone and “prosody” — the rhythm, stress and intonation of our speech. “When people talk to dogs, dogs pay attention to the melody and the mood to predict what is happening or what will happen next,” explains Fischer.
Fenzi says that dogs can just as easily respond to gibberish as to real English words; “I could go through every level of AKC obedience from the bottom to the top saying, ‘Kaboola,’ and the dog could succeed.” In many cases, dogs may be understanding tone rather than individual words.
“One of the most notable differences between novices and professional trainers is the ability to modulate the prosodic features of their speech,” notes McConnell. “The pros learn to keep problematic emotions out of their verbal cues, like nervousness in a competition, and to use prosody to their advantage when it’s advantageous, for example, to calm a dog down or to motivate him to speed up.”
In another study, Ramos explored whether, when taken out of context, dogs knew the words relating to toys they were thought to know. Most did not, much to the surprise of the owners. When the verbal skills of Fellow, a performing German Shepherd from the 1920s, were tested outside their customary contexts, Fellow knew only some of the words and actions that his owners thought he understood.
While many owners deem their dogs to be word-savvy, their reports tell a different story. The Pongrácz survey found that many words and phrases were executed only in contextually adequate situations (for example, saying “bedtime” when it’s dark and you’re in your pajamas rather than at noon when you’re in your work clothes). As with Fellow, this suggests dogs might not be attending to only words themselves.
Put Words to the Test
McConnell initially thought Willie knew the name of her partner, Jim. “To teach Willie, I would say, ‘Where’s Jim?’ and Jim would call Willie over. When Willie consistently went to Jim, I’d say it as Jim was driving up, and Willie would run to the window. One day, Jim was sitting on the couch, and I said, ‘Where’s Jim?’ and Willie ran to the window, all excited. This difference in definitions is more common than people realize — dogs don’t have the exact same concept of words that we do.”
While there is no question dogs can understand verbs, their definitions might differ from ours. McConnell shares a classic example that she learned from Ian Dunbar, founder of the Association of Pet Dog Trainers. “What do dogs think ‘sit’ means? We think ‘sit’ means this posture we call ‘sitting,’ but if you ask a dog who is sitting to ‘sit,’ he will very often lie down. To him, ‘sit’ might mean get lower, go down toward the ground.”
Many people tend to overestimate their dogs’ facility with words and assume that dogs and humans have a shared understanding. Because a dog responds in one context and not in another doesn’t mean he is being disobedient. As Tom Brownlee, master trainer with the American Society of Canine Trainers and instructor in Carroll College’s anthrozoology program, candidly advises owners, “If a dog’s not getting ‘it’ — whatever ‘it’ may be — then you are doing something wrong. It’s our job to help them understand.”
When you talk to your dog, consider that the words you speak might not carry the same meaning for both of you. Instead, other aspects of communication might be more relevant. Maybe the real lesson is that context, prosody and tone — rather than dictionary definitions of words — are vitally important for human communication, too.

Good Dog: Behavior & Training
Looks aren’t everything, but they do play a role in communication
October 8 2012
Dogs excel in their role as our best friends. Spooning with us on a cold night, they seem almost hyper-domesticated. If there were a gold medal for “Achieving Domestication,” dogs would win it.
Some days, however, the story is quite different: chasing squirrels, digging up newly planted flowers, eating — then throwing up — grass, romping in a mud puddle post-bath, rolling in an overripe carcass. At these moments, we’re apt to look at our four-legged companions and say, “Really? You’re domesticated?” And, of course, they are. This mixture is what makes dogs, dogs — one minute, dressed in a Superman costume and the next, shredding and eating said costume.
People often cite life experience and breed when trying to account for the ways dogs behave. Who hasn’t heard, “He’s a rescue and was probably abused — that’s why he’s shy,” or “She’s a Labrador Retriever, so she always has a ball in her mouth”? Dogs of unknown origin are described in a similar fashion, relative to their possible breed identities: “Petunia kind of looks like a Chihuahua, but she definitely has that Border Collie eye.”
According to Christine Hibbard, CTC, CPDT-KA and owner of Companion Animal Solutions in Seattle, Wash., when associating a dog with the “look” or “behavior” of a particular breed, it’s important to remember that “the way dogs look and their actual genetics can be very different.” That, at least, is what studies are showing. As Victoria Voith, DVM, PhD and boardcertified veterinary behaviorist at Western University of Health Sciences in Pomona, Calif., explains, “Mixedbreed dogs are a collage of features of their ancestors. So much so that they often don’t look like any of their immediate parents or grandparents. In fact, they may look more like other breeds.” DNA tests often reveal that dogs are not simply a cross between two purebred parents. Instead, tests come back as 25 percent of this, 12.5 percent of that and a pinch of a few others. Since a dog’s looks and his genetic code can be on very different pages — sometimes in different books altogether — attributing a dog’s behavior to its “look” can some- times be a faulty assumption.
What about purebred dogs? Do these dogs from concentrated breeding pools give clues about why dogs act as they do? The AKC and other breedcertifying organizations certainly ascribe global attributes to breeds: The Schipperke is confident and independent; Boston Terriers are friendly and lively; Chows are independent and aloof; Clumber Spaniels are gentle, loyal and affectionate.
Breed standards, however, are simply guidelines. As Denise Herman, CTC, lead trainer and founder of Empire of the Dog in NYC, says, “When you get a puppy of a particular breed, people think it’s a blank slate, but it’s really an unknown slate. Breed gives an indication of where that unknown slate may go, but not all Border Collies herd, not all Huskies pull sleds and some Chows like everyone equally. A puppy of a particular breed is an unknown slate with the possibility of those characteristics.”
No Two Alike
The controversial practice of dog cloning provides a great example of the limits of behavior assessment based on genetics. In Dog, Inc., Pulitzer prize– winning investigative reporter and Bark contributor John Woestendiek explains how, after spending $20 million to clone their beloved dog Missy, Joan Hawthorne and John Sperling found Missy’s successor different from the original. “Missy was robust and completely calm. Missy wouldn’t come through my home and knock over every wine glass … They’re not at all alike,” says Hawthorne. Their genetics were the same, but personalities? Not so much. Even clones aren’t clones.
While genetics and life experiences certainly contribute to who dogs are, they’re not the entire story. The other part of the picture is in plain sight.
Breed standards specify required physical attributes pertaining to the tail, the ears and the coat, among other things. Most of these individual attributes, of course, appear across breeds and even in dogs in general. As a result, dog physical appearance — and its implications for how dogs communicate and how they are perceived — can be examined in its own right.
The famous Russian silver fox experiment is a clear reminder that the behaviors animals demonstrate can in some ways be linked to the way they look. In a few generations, foxes bred for docility and friendliness toward humans began to look quite different from those who were fearful of humans. As Stephen Zawistowski, PhD, CAAB and science advisor to the ASPCA, summarizes, “As the foxes became more tame, they began to develop a more ‘dog-like’ appearance, with piebald coats and floppy ears.”
The signals a dog has at its disposal may simply be a matter of basic equipment. As Zawistowski observes, “There are some things that are anatomically not possible for a dog to do, simply based on its anatomy. How can you tell if a Basset Hound has his ears up and forward? A Rottweiler can make a great lip pucker, but how on earth can a Bulldog pucker?” To be sure, the lack of overt behavioral signals does not suggest a dog is not feeling a particular emotion, or even that he might not adopt different strategies to convey them. But the implication is clear: The perception that Rottweilers are aggressive and Basset Hounds are laid-back could be a function of their physical features — and thus, the behaviors they can perform — rather than their mental processes.
With this in mind, could dogs’ physical appearance affect how they communicate? Or even, for that matter, how they’re treated by other members of their species? When a Great Dane comes across a French Bulldog, olfactory cues will reveal that the French Bulldog is, in fact, a dog, but does the Great Dane think to himself, “Hello my long-lost, thirty-times-removed cousin!” or “What the heck? You smell like a dog, but I don’t understand what you’re saying.”
Here to translate for the dogs is Jim Ha, PhD, CAAB, research associate professor and staff member of Companion Animal Solutions in Seattle, Wash.: “The way dogs look — their morphology — can definitely change the quality of their visual signals. Dogs who are more infantile in appearance — paedomorphic dogs like French Bulldogs, Pugs and Cavalier King Charles Spaniels — are nice examples of how we are handicapping the dog’s ability to signal properly. But we also find that dogs who are not paedomorphic in appearance can have trouble signaling and communicating with one another as well. Signaling difficulty is not only associated with paedomorphic dogs.”
The changes we’ve made to dogs’ physical appearance do not necessarily make it easier for dogs to communicate with one another. Ha suggests that many aggression issues stem from misuse of signals and miscommunication between dogs.
Voith has a similar assessment: “Based on clinical experience, but not tested systematically, dogs that are fuzzy or black are often attacked by other dogs. I think that is because their social signals are not easily detectable — if at all. Subsequent to being attacked, black or fuzzy dogs become defensively aggressive towards other dogs, generally on leash.”
Herman agrees. “For any dog with a lot of fur or hair, you can’t see muscle tension, and it’s harder to read stiffness. Is a Komondor having a piloerection [raised hair along the dog’s back]? I have no idea.”
Or, take tails. Dog tails come in a spectrum of shapes and sizes. Are they important for dog-dog communication? Humans certainly take note of tails; when asked to assess dog behavior, we pay an inordinate amount of attention to the tail (possibly because we do not have one). Does a Labrador look at a Corgi and think, “Umm, excuse me, sir. I’m having a hard time understanding you. I believe you’ve misplaced your rear-end thing.” For another species commonly found lounging around our homes, tails are highly relevant. While a graduate student studying with noted ethologist John Bradshaw, Charlotte Cameron-Beaumont found that cats more readily approached, and approached in a friendly manner, a cardboard cat silhouette whose tail was in the “tail-up” position as opposed to those cat silhouettes with their tails down. Tails play an important role in cat-cat greetings (good luck, Manx).
When the dog researchers explored how dogs respond to other dogs’ tails, they pulled out the big guns: a model robot dog resembling a Labrador Retriever. Apart from its tail, the “dog” was motionless. The researchers found that when the robot dog had a long wagging tail, it was approached more than when it had a long still tail, which as you probably assumed, suggests that the tail conveys emotional state, and that wagging is more inviting than not wagging. When it came to short tails, the story changed. There was no difference between how the robot dog with a short/still and a short/wagging tail was approached. It appears that the longer tails were most effective at conveying emotional information, and since short tails are hard to read, they might not be read at all.
For Herman, the implications are obvious. “When you dock tails, it takes away part of their communication signal. It’s the dog version of Botox. Ear cropping falls in the same category. Dobermans with cropped ears ostensibly look alert to other dogs. They can’t be read [accurately] because they can’t change.” It’s difficult to derive cues and information from cropped ears. If anything, their constantly alert position could mislead other dogs.
E’Lise Christensen, DVM and boardcertified veterinary behaviorist in New York City, agrees. “I think cosmetic alteration could affect communication with other dogs. It certainly [has an impact on] assessments by owners, because they forget to look at the stump of the tail for movement and tension. Ears that are too cropped mean owners have to look for muscular movement at the skull level rather than the pinna, the outer part of the ear, where we customarily look. Flat faces make it more difficult to read small muscular movements.”
Herman suggests that taking note of a dog’s morphology can give owners a better appreciation for their dog. “It’s hard for other dogs to see that a Chow is really stiff, simply because he is [engulfed] in a ball of hair. It can be helpful for pet dog owners to recognize that what dogs have or do not have at their disposal could add confusion to dog-dog communication. This appreciation could help owners empathize with their dog, instead of blaming their dog or feeling angry for the dog’s behavior.”
Hibbard reminds us that the issue at hand can be twofold. “If you can’t see the ears, that’s one problem. But if you can see the ears but the dog uses them wrong, that’s another problem.”
It’s All About Us
Training, life experience, genetics and psychological disorders are the common suspects for “out-of-sync” behavior, but how a dog looks — or rather, sees — is often overlooked. In 2003, professor Paul McGreevy, DVM and researcher at the University of Sydney, and his colleagues discovered that, contrary to popular belief, all canine eyes are not the same. Shortnosed dogs have what is called an area centralis, which allows them to focus more clearly on the world in front of them, like humans, while long-nosed dogs have a visual streak, which enables better peripheral vision. There’s a physiological reason why a long-nosed dog would take off after something way in the periphery while you and a shortnosed dog continue to sit on a park bench wondering what the long-nosed dog saw.
It stands to reason that these differences would not only affect how dogs see the world around them, but also how they attend to us humans, and that’s exactly what we find. Dogs are quite adept at following our pointing gestures, but brachycephalic (flat-faced) breeds, with their more forward-facing eyes, follow these gestures better than dolichocephalic (long-nosed) breeds. In turn, this sense of being seen and responded to accordingly (or not) may affect how we perceive and relate to dogs.
Undoubtedly, dogs are a composite of their genes and individual life experiences. But the physical features that they come with, or that we give them via docking and breeding, can contribute to how they interact with others and are perceived by dogs and humans alike. When thinking about why your dog behaves the way he does, it can be helpful to be superficial and look at what’s right in front of you.
Good Dog: Studies & Research
Researchers exploring the canine point of view
June 26 2012
Doesn’t it sound reasonable to study the behavior of cranes? After all, cranes are quite different from humans — they can f ly, spend lots of time on one leg and don’t need an external GPS to find their way to Florida.
But what if we replace “cranes” with “dogs”? Why study dog behavior? Unlike cranes, dogs are not a wild species with feathers, migratory patterns or conservation needs. Dogs have lived alongside humans for at least 15,000 years; are ubiquitous in human cultures; and regularly find their way into our literature, hearts and beds (also unassisted by GPS, it must be noted). We think we know dogs just fine. What’s the point of all this scrutiny?
Dogs aren’t new in the world of research.
In other academic arenas, Marc Bekoff, Ian Dunbar, Michael Fox and the late Frank Beach all conducted extensive investigations into canine social behavior, physiology and development. And of course, in 1965, Scott and Fuller produced their seminal text, Genetics and the Social Behavior of the Dog. Konrad Lorenz, Nobel Prize–winner and acclaimed ethologist, also had dogs on the brain; if you doubt that, pick up a copy of his book, Man Meets Dog.
Despite the thousands of years dogs and humans had spent in close proximity, scientists had never explored either the relationship or the factors that allowed dogs to become our social partners.
Dogs’ perspective as members of the human environment was missing from the equation. “It’s odd that this companion animal who has been at our side longer than any other is really not well understood,” observes Kristina Pattison, researcher at the University of Kentucky’s Comparative Cognition Laboratory.
“Dogs suffer from a failure of imagination by those asking the questions,” explains Mary Lee Nitschke, professor of psychology, Certified Applied Animal Behaviorist (CAAB) and founding member of the Association of Pet Dog Trainers (APDT). “If you already ‘know’ a dog can’t think, you’re not going to ask whether it can think.”
In 1994, imagination and an open mind prompted the creation of the Family Dog Project at Eötvös Loránd University in Budapest, initially under the guidance of Vilmos Csányi, and now headed by Ádám Miklósi. Rather than taking the position that dogs’ place among humans was unworthy of scientific investigation, they put the dog, and the dog-human relationship, under the microscope.
While previous studies had investigated owners’ intimate feelings toward dogs, the dog’s perspective on this relationship had not received comparable attention (probably because canine penmanship is quite poor and they rarely complete questionnaires in a timely fashion).
To explore the dog’s perspective, the Budapest group placed companion dogs and their owners in a modified version of the Strange Situation Test, a behavioral experiment initially created to explore the mother-infant relationship from the infant’s perspective. The test is simple enough. In a novel environment, a dog experiences separations from and reunions with an owner and a stranger while a researcher records the dog’s behavioral changes. It turned out that dogs behaved much like human infants. The conclusion? The dogowner relationship, like the motherinfant relationship, fulfills the criteria for attachment.
This research sparked a shift in perspective and demonstrated that there’s a lot we don’t know about dogs and their relationships with humans. For example, it was commonly assumed that in order for a dog to develop an attachment bond with an owner, the dog needed to be acquired as a puppy, and within a narrow age window at that. But when the Strange Situation Test was applied to adult shelter dogs who had low or restricted human contact, these dogs also displayed attachment behavior toward designated “owners.” An additional study confirmed this; guide dogs bond with their blind owners even though their relationship forms later in the dog’s life. The takeaway message was twofold: older dogs can bond with new owners, and our assumptions about dogs are not always spot on.
Since then, scientific inquiry into dogs and the dog-human relationship has exploded. “It’s almost like dogs have been rediscovered by scientists, and there are so many different aspects they can study,” notes Mychelle Blake, APDT executive director.
Dogs have now attracted the attention of a range of disciplines, from animal behavior and psychology to evolution, genetics and veterinary behavior.
Nowadays, companion dogs, working dogs, village dogs and even shelter dogs have become study subjects.
While some are interested in contributing to a growing portfolio of insights into “the dog,” others have something else in mind. “Some of the present research does not directly pertain to dogs and the humans they live with,” notes Márta Gácsi, researcher with the Family Dog Project. “Comparative studies may be examining the roots of different human social behaviors, and not necessarily concerned with the dogs themselves.”
The Duke Canine Cognit ion Center, which is part of the university’s Evolutionary Anthropology Department, takes this multifaceted approach. Their website explains, “Our goal is to understand the flexibility and limitations of dog cognition. In doing so, we gain a window into the mind of animals as well as the evolution of our own species.”
“Research also has direct application for dogs and owners,” reminds Gácsi. Jennifer Bentlage, who’s working toward a master’s degree in the cognitive biology program at the University of Vienna’s Clever Dog Lab, agrees. “If I can explain the purpose of my research to my parents, then it’s worthwhile.” Bentlage, who is currently exploring social learning, has recruited her own dogs, Monty and Michel — shelter dogs from Spain and Greece, respectively —as test subjects for her project.
“I am very interested in the dog’s cognitive abilities because this relates very strongly to the pet owner,” explains Ian Dunbar, founder of the Association of Pet Dog Trainers (APDT), veterinarian, animal behaviorist and director of the Center for Applied Animal Behavior in Berkeley, Calif. “The importance of cognition is so that people realize who dogs are and what they can and cannot easily grasp.”
Dog cognition, a seemingly technical phrase, is simply a catch-all-term that describes dogs’ attention, memory, perception, problem-solving and mental imagery skills. As you might imagine, the questions are endless.
Crystal Thompson, a self-proclaimed dog-seminar junkie from St. Paul, Minn., thinks dog cognition research is paramount. “We have learned so much in the last few years that it behooves anyone interacting with dogs — owners, trainers, shelter workers, vet staff — to do a self-audit, to check their assumptions about dogs against what research is finding.”
We expect dogs to act a certain way, and they do.
Dogs have the potential to move in tandem with humans, stopping when we stop and starting again at our first subtle sign of forward motion, but magic is not the mechanism (although the resulting experience can certainly feel magical!). Instead, research finds that dogs are astute surveyors of human behavior, and everything from our gaze to our larger body movements provides meaningful information.
For example, researchers have found that the right side of the human face better expresses our emotional state, and when looking at other humans, we display what’s called a left-gaze bias, or a propensity to look toward the right side of the other person’s face, where all the clues are. When dogs look at human faces, they also display a left-gaze bias. Could your dog be sensitive to your emotional state? Yup.
And just as social contexts and relationships matter to you, they matter to your dog. Research has shown that if a stranger approaches your dog in a threatening manner, your dog will respond with avoidance/aggressive behavior. But if you approach your dog in the same way, your dog responds with tolerance and contact-seeking behavior. In short, dog owners feel connected to and supported by the dogs they live with, and for good reason.
But sometimes, dogs don’t act the way we want them to.
This is where cognition research comes in. Is the dog’s assessment of a situation comparable to the human’s, and if not, what is the dog’s vantage point?
Numerous studies have found that dogs attend to human communicative intent. As your significant other may have told you (possibly more than once), how you say it matters. Want a dog to come to you from across the room? Research by Patricia B. McConnell, and beloved Bark columnist, explored how different sounds affect dog behavior: “Four short notes were more effective at eliciting a come response and increasing motor activity levels than one longer continuous note.” In the real world, yelling “COOOME!” (akin to one longer continuous note) will most likely result in exasperation, but short, rapidly repeating notes, like “Pup-pup-pup,” will likely bring a dog on over.
Are dogs cooperative or competitive? Are dogs like chimpanzees, who more readily locate food in competitive situations when prohibited from going to a certain location. (A possible chimp translation might be: “The only reason you’re telling me not to go there is because that’s where the good stuff is, you jerk.”) Nope, dogs fare better in cooperative situations, finding food when informed of its location in a friendly, cooperative tone. Bringing this back to daily life: if you wonder whether the dog-human relationship is based on competition or cooperation, this is another check mark on the cooperative ballot.
Understanding the dog’s perspective is important because incorrect assessments of behavior can cause problems in dog-human relationships. “People think the dog is doing something to create trouble,” explains Floridabased Soraya Juarbe-Diaz, DVM, and board-certified veterinary behaviorist. “Almost everything on TV is about conf lict — a fight, someone trying to win or cheat; it’s very confrontational and we are always looking for a fight for superiority. Fortunately, animals don’t always work that way.”
And why can’t dogs just do what we want them to do? In one study, dogs who performed a 10-minute sit-stay (meaning, they exerted self-control) gave up quicker on a subsequent task than dogs not required to exert that initial self-control. This initial act of controlling their behavior depleted their energy, thereby adversely affecting subsequent behavior.
The consequences for not understanding dogs’ behavioral capacities can be dire. “The biggest cause of death in dogs is behavior problems, and failure to inhibit is at the root of many behavior problems,” explains Pattison.
“He barks all the time — failure to inhibit barking; he growled — failure to inhibit an aggressive response. He jumps up — failure to inhibit jumping. We expect dogs to forgo their species-typical behavior patterns and inhibit them in favor of a response we find more appropriate.” The applications for dog cognition research are vast. “The cognitive research says, look, the dog is not doing this to get your goat, he’s not doing this to diss you, he’s not trying to dominate you and take over the world,” says Dunbar. In other words, he’s just being a dog. Kelly Ballantyne, DVM, finds that the “final showdown” misconception often results in inappropriate owner-dog interactions and worsening of the dog’s behavior.
Dog-care professionals are taking note of this growing body of research. In 2004, APDT began including a science track at their yearly conference. Their mission is not simply to saturate trainers with research, but also to provide education about research methods and the nuances of study design. APDT leadership hopes that as more research hits the press, trainers will read studies with a critical eye and make informed decisions about their application for training. As Blake points out, “One study simply advances a hypothesis, and ongoing research is needed to improve our understanding of dogs.” “Research helps broaden our view of what is possible,” add Nitschke. “The fact that cognitive studies sometimes disagree with each other is wonderful, because it means there is more for us to look at. Different studies with different results broaden our vision of what is possible.”
Research also has application in the classroom. “My students were blown away,” reports Johnna Chamberlain, who teaches at the Lang School in New York City, a school for gifted children with learning differences. That’s how she describes her students’ reaction to “Dogs Decoded,” the NOVA special on dog cognition. “[My students] hadn’t considered that dogs were communicating through their barks, bodies or tails. Since [my students] might have social or emotional delays in relation to perspective taking, it was a big deal for them to consider their own relationships with pets and realize that dogs are communicating and thinking in their own unique way.”
Thompson looks at the breadth of cognition research from a different angle; she wonders whether owners are providing for their dogs’ mental needs. “It’s important for owners to realize that dogs have real mental abilities and needs. Putting food in a dog’s bowl is just wasting his brain. It’s the little things — Kongs, Tug-a-Jugs, hiding kibble around the house — it’s not hard, and it’s a simple way to engage their natural abilities.”
“How you interact with dogs often depends on your impression of their abilities,” notes Juarbe-Diaz. Reframing our expectations, with a little help from research, could set up dogs to succeed in our primate world. As Gertrude Stein said, “I am because my little dog knows me.” Shouldn’t we do the same for dogs?
Good Dog: Behavior & Training
Why do they do it?
June 22 2012
On a beautiful, warm afternoon, I watched a group of dogs frolic in a dog park. Suddenly, I heard a woman’s high-pitched yelp, followed by the pounding of human feet. There was no need to look; it was obviously about humping, which we can also refer to as mounting.
Dogs hump the air, they mount pillows and blankets, and they can be found poised behind the neighbor’s dog or befriending Uncle Joe’s leg but not Uncle Albert’s. Mounting pops up in many contexts and is directed toward any number of objects, both animate and inanimate. Apart from giving mounters silly nicknames like “the humping bean” or “Sir-humps-a-lot,” what are we to make of all this bumping and grinding?
Talking about dog behavior is like talking about politics: everyone has an opinion. According to Cynthia Heyman of Utah, her three-year-old Danish-Swedish Farmdog, Jet, is a play-humper. “Jet is intact, and he likes to hump when he plays. He seems to like the boys better than the girls. Last weekend, he was humping a neutered Aussie who humped him right back as they were playing.”
For Margaret Duclos of Seattle, Wash., mounting is related to excitement and arousal. “One of my dogs sometimes humps the other when we get into the car — usually only when it has been a few days since we’ve gone somewhere and he is especially excited.”
On the other end of the spectrum, some attribute humping to dominance. Brigitte Reed of Salt Lake City, Utah says, “My female dog, Snickers, who is spayed, will hump our male dog, Kitna. The reason being is she is alpha and she is asserting her dominance over him. Putting him in his place, as it were.”
When a dog’s a humper, there’s inevitably an owner nearby with a story, usually one that describes who or what is mounted (the stuffed animal, the cat, other dogs) and the context in which the humping occurs (when guests come over, at the dog run, during obedience trials). Owners postulate that sex, breed, age, reproductive status and even size might provide information about humpers. Most of these stories culminate in questions — “Why in the world does she do this? Aren’t males the humpers?”— or impressions, anything from “It’s just play” or “She’s dominant” to “He’s quite popular!”
As you might expect, animal behavior researchers have a lot to say on the topic. When exploring any behavior, we can turn to the insights of Nobel Prize–winner and famed ethologist Niko Tinbergen for help. Tinbergen’s “four questions” provide a reliable framework within which to understand why animals behave the way they do. One of Tinbergen’s questions is particularly apt: “How does a behavior develop during an individual’s lifetime?” After all, behaviors don’t simply fall from the sky, land on a dog and voilà! Mounting! For nearly as long as ethologists have studied dogs, they have taken note of dogs’ tendency to hump outside of reproductive contexts.
In the early 1970s, University of Colorado ethologist Marc Bekoff, PhD, began investigating the development of canid social behavior. Bekoff observed the interactions of young canids, pairs of three- to seven-week-old wolves, coyotes and dogs. Particularly among the dog puppies, mounting, clasping and pelvic thrusting appeared early on in play. While males mounted more than females, females also engaged in aspects of the behavior. Dr. Sunil Kumar Pal, assistant teacher at Katwa Bharati Bhaban School in West Bengal, India, got similar results when investigating social behavior of young, free-ranging domestic dogs. By six weeks, both male and female puppies were mounting, clasping and pelvic thrusting.
“It’s what dogs do. It’s a completely normal behavior,” explains Carolyn Walsh, PhD, associate professor of psychology at Memorial University of Newfoundland, who studies the nuances of dog behavior in dog parks. “Both males and females mount, regardless of whether [they are] sexually intact or not.” Celeste Pongrácz, a Mudi breeder in Hungary, finds that mounting can change with hormonal shifts. “Right now, we live with seven bitches, and when somebody is coming into season or is in season, some dogs want to hump, and others ‘ask’ to be humped. Regardless, it always involves the bitch in season.” Studies find that neutering males can decrease mounting, but certainly does not stop it in its tracks. After all, there is more to it than hormones. (Alas, not a single study noted if Barry White songs were playing in the background at the time the behavior was exhibited.)
From tail wagging to barking, dog behavior is riddled with nuance. A wagging tail might convey “I’m quite scared” or “This is the best day ever!” Like tail wagging, mounting is far more complex than it may appear, and there is not one simple explanation. But there are some likely candidates.
In many cases, mounting is related to a surge of emotion, such as feeling anxious or being aroused (in this context, “arousal” means general stimulation). In a recent investigation of dog park behavior, Walsh and her student, Lydia Ottenheimer Carrier, found that the dogs doing the most mounting were also doing the most playing. Walsh explains, “Dog parks can be quite stimulating, and for those who are highly aroused physiologically, mounting behavior could easily come out. There can be such a buildup of social motivation and the desire to affiliate that some of that energy spills over into the sexual motivation system. You see sexual behavior coming out, but it’s mostly out of context.”
General arousal or anxiety is not restricted to the dog park. Stimulation easily translates to everyday situations: a new person comes over, a new dog is introduced or a dog is cooped up in the house all day. “One of my dogs humps the others when I grab the leashes, or otherwise am doing things that signal going somewhere,” says Duclos.
Dawn Cleary, owner of Blue Cerebus Dog Boutique in Madison, Ind., attributes mounting exhibited by one of her Golden Retrievers to excitement. “When my Frisbee champ catches the Frisbee, my littlest one likes to run out and hump her. It’s the only time she does it … sort of like she wants to share in the glory of the Frisbee being caught.” (Is this the canine equivalent of painting your face and watching the Super Bowl?)
So why mount? Peter Borchelt, PhD, and Certified Applied Animal Behaviorist (CAAB) in New York City, reminds us, “There are only so many behaviors a dog has access to, and dogs do what is part of their species-typical behavior. It is something they know how to do.” Since their options are somewhat limited, a dog, rather than read the funny pages during downtime, might be inclined to get to know a stuffed animal a little better.
What else could mounting be about? For some owners, mounting equates to dominance and control, words that suggest you might not want your four-legged friend engaging in this behavior.
But what is dominance, and where does mounting fit in? According to Carlos Drews, PhD, dominance is not a characteristic, but rather, relates to describing interactions between two individuals. “Dominance is an attribute of the pattern of repeated, agonistic interactions between two individuals, characterized by a consistent outcome in favour of the same dyad member and a default yielding response of its opponent rather than escalation … Dominance is a relative measure and not an absolute property of individuals.” The American Veterinary Society of Animal Behavior defines it as “a relationship between individual animals that is established by force/aggression and submission, to determine who has priority access to multiple resources such as food, preferred resting spots and mates.”
Is mounting associated with dominance? Not necessarily. Becky Trisko, PhD, behaviorist and owner of Unleashed in Evanston, Ill., studied dog-dog interactions in the dog daycare setting. Mounting was not associated with status-related (“agonistic”) behaviors like aggression and submission, but instead was correlated with play and other affiliative behaviors. For example, a dog who muzzle-licks another dog — a behavior often associated with “Let’s be friends. Like me! Like me!” — might also mount the same dog. If mounting indicated status or a dominance relationship, we would expect mounters to receive submission from other dogs, but that’s not what we’re finding. Likewise, a dog is probably not trying to dominate the dog bed he just mounted.
Mounting occurs in a variety of contexts and can be surrounded by many different behaviors. Humping could be an assertive behavior related to social bonds rather than competition for resources or status. In friendly contexts, mounting could be an attention-getting behavior to instigate an interaction. As Trisko explains, “Among preferred play partners (scientific jargon for friends), it almost seems to be a way to get the other to play. A dog might do a play bow, bark and paw at a dog. If the second dog isn’t really responding, mounting will often get a rise out of the dog, and then they’ll play.”
Trisko also suggests that mounting among friends is associated with bond-testing. “This is the idea that dogs perform potentially annoying behaviors like mounting to test the strength of the recipient’s investment in the relationship. It’s like saying, ‘How much will you put up with?’ ‘How much do you really like me?’” Since mounting seems to appear in affiliative, not aggressive or status-related contexts, this is a provocative possibility.
At the same time, mounting is not always related to friendship. Aimee Moore, CPDT, of Dog’s Best Friend Training in Madison, Wisc., says, “I don’t think there is one simple explanation, but with unfamiliar dogs, or often even with owners, it can be pretty rude and related to status.”
As Borchelt, who has treated behavior problems for more than 30 years, observes, “Mounting could be part of a suite of behaviors associated with aggression, such as high posture, resource guarding, direct stares, and threats and standing over. But mounting, by itself, doesn’t indicate a status issue. By itself, mounting might not mean a lot.”
He also feels that it could even be problematic to ascribe the label of “dominance” to a dog who is a mounter. “If you perceive a dog as dominant because he mounts, you might think you have to take steps so that the dog isn’t dominant to you — maybe always make the dog heel, which could cut back on sniffing, exercise and dog-dog interactions, or use intimidation to make the dog follow explicit rules. This could have negative consequences for the relationship.”
But there is more to the story than the mounter. Not all dogs welcome being mounting. Jessie Nelson of New York City notes that her dog Gracie, a mutt who more closely resembles Falkor the Luckdragon from The Never Ending Story than a member of Canis familiaris, changed her relationship with mounting as she aged. As Nelson recalls, “Gracie used to let other dogs hump her, and then they would continue playing. Now she will freak out at dogs who mount her.”
What to Do?
Training and dog-owner communication can help a humper maintain friendly interactions with dogs and humans alike. Moore suggests various training techniques. “I would work on obedience so I could get my dog’s attention when she starts to focus on another dog. I would also work on call-aways — dog greets and sniffs appropriately, then call her back and reinforce for that behavior. This way, you are catching her before she mounts.” Since mounting is often associated with arousal levels, when working on mounting, Moore recommends relaxation protocols, down-stays or teaching an alternative behavior. Angela Limburg of Chicago, Ill., tries redirecting her dog. “My boy humps his bedding … It seems to happen when he is overexcited. We try to redirect him — usually, offering cheese or cookies works.”
But at the end of the day, mounting is still a tricky behavior to figure out. “Mounting is one of those behaviors you would not want to have a single answer for,” explains Borchelt, and Bekoff agrees. “It is complex, and we don’t want to say mounting is always this or always that. What we are learning about animal behavior is that we need to be very careful about generalities. Dogs don’t always greet each other by sniffing the anogenital region, and they don’t always circle before they lie down.”
It is not uncommon for owners to say, “I am deeply embarrassed that she humps.” Some sense disapproval from other owners: “I feel a social imperative to stop his humping.” These feelings are understandable, because for many, dogs don’t simply contribute hair to our favorite black pants; they are our family members and best friends. Which means that some of our best friends are humpers.
“I think the sense of embarrassment is not well placed,” remarks Walsh. Given that mounting is a normal part of a dog’s behavioral repertoire, owners can eliminate some of the stress and anxiety by getting to know mounting as it pertains to their individual dog.
When trying to get behind any behavior (pun intended), Bekoff recommends becoming an at-home ethologist. “Get a paper and pencil, and watch and record what happens before and after the behavior of interest. This can tell you more about the behavior itself.” This technique can help you determine when a behavior needs to be managed and when it’s just fine.
If dogs could talk — and they actually are with their behavior — they’d ask us not to clump mounting into one universal meaning. So what’s your dog’s mounting behavior telling you?
All in all, when we’re trying to figure out a behavior, we’re better served by observation and understanding of its roots than by the stories we tend to tell ourselves and others.
Good Dog: Behavior & Training
More than fun and games
February 15 2012
You have an all-day work event, your dog walker comes down with something and your back-up help is out of town. Then you see the ad for a local dog-daycare facility: “We can help! We offer 12 hours of fun and socialization for your dog.” The message is accompanied by cute photos of pooches at play. Should you be sold?
Across the U.S., dog-daycare businesses — franchises and single-owner operations alike — are flourishing. They offer your dog what you sometimes cannot: playmates, companionship and supervision when other commitments take you away from home. Most keep hours similar to those of daycare centers for children: drop your dog off before work, pick her up afterward.
Do dog daycares provide a necessary service for both dogs and owners? Are all daycares created equal? Is dog daycare an option you should consider? The answer is a resounding “It depends.”
Marc Bekoff, PhD, a University of Colorado ethologist who has studied dogs and their wild relatives for more than four decades, gives the concept of dog daycare a thumbs-up: “I love the idea. I think they provide a great function. At the same time, daycare should not replace people spending a good deal of time with their dogs.” E’Lise Christensen, DVM, and board-certified veterinary behaviorist in New York City, agrees “For healthy, active, social dogs, daycare can be a great outlet for getting exercise and social enrichment.”
In fact, this belief is exactly what originally spurred the development of the dog daycare industry. “In the early 1990s, training professionals found there was a need for dogs to get out of the house, socialize and engage in mental stimulation and physical exercise,” explains Melinda Miller, hospital director at Smith Ridge Veterinary Center in South Salem, N.Y.
Social play and mental stimulation are the main reasons many people choose to enroll their dogs in daycare. Mat Zucker of New York City has been taking his co-pilot Ezra to Paws in Chelsea three times a week for the last nine years. “When Ezra was a puppy, it was a great place for him to burn off energy, be social and run around. We were worried he would be bored home alone.”
Zucker makes a good point. The complex process of domestication did not shape dogs for solitary living (raise your hand if one is napping at your feet as you read this). On the other hand, dogs did not evolve to engage in all-day play sessions either.
The Social Scene
In the daycare setting, dyadic play (play between two dogs) is probably the most prevalent type. A recent study* investigating social play in adult, group-housed dogs at a boarding kennel found that of 343 social-play bouts, all but one were dyadic in nature. “This is not surprising,” notes Alexandra Horowitz, PhD, and term assistant professor of psychology at Barnard College, who has studied dog play behavior extensively.** “Dyadic play is an easier dynamic for most dogs than triadic or larger-group play. In a bigger group of players, it would be hard to have play signals in all those different directions, and a dog could certainly miss something. Because of the complexity of play, this high-paced, rambunctious activity needs a lot of coordination.”
The idea of giving dogs space to play might seem straightforward enough, but there’s more to it than simply providing square feet. Numerous factors can influence the presence, or absence, of happy frolicking. While a dog’s physical size warrants consideration when forming daycare playgroups, play style is paramount. Becky Trisko, PhD, behaviorist and owner of Unleashed in Evanston, Ill., knows this well. “A good daycare surveys play styles and groups dogs accordingly. At the same time, [it] also allows flexibility between groups throughout the day to manage personalities and excitement levels.”
When it comes to play, turning up the dial is not always better. As Miller explains, “Hyper dogs allowed to get into a frenzy and maintain that level of excitement all day can be worse in the home than they were before they went to daycare. Staff members who help dogs learn about relaxed play and recognize when dogs need time out or a change of pace and rest are helping both dog and owner.” Trisko agrees. “Owners often assume that an exhausted dog is a happy dog. But an exhausted dog could also be an irritated dog.”
In a well-run daycare, these issues are addressed by handlers who ensure that dogs engage in the congenial play their owners envision. While no formal research has been done to validate these numbers, the consensus is that an ideal handler-to-dog ratio is 1:10, or 1:15 at the outside (Christensen recommends a ratio of 1:5). If groups grow in size, so too should the level of human attention. But even with multiple human hands on deck, large dog groups can be challenging to manage. Kate Senisi, a former daycare employee, knows this firsthand. “Daycares that create multiple, smaller groups within a space, as opposed to one large group, allow for more direct supervision of the dogs. But that also means that the daycare has to provide additional staff to cover the new groups,” she says.
Done right, supervision gives dogs the variety they need within a complex environment. Though many daycares tend to highlight “all-day play,” a quick review of online daycare videos reveals dogs engaged in any number of activities. Some dogs play, some watch; others investigate something on the floor, jump on a handler, sit in a handler’s lap or lie on the floor. In other words, individual dogs have a range of interests that shift moment by moment, and good supervision can facilitate this variety.
According to Horowitz, it’s important that dogs have options and control. “Not to say that the dog is dictating the day, but that the dog has options to be social, to be with a person or by themselves. That would be the highest-quality day: a lot of things to do and being able to make choices about when and with whom to do it.”
Handlers perform a critical role in promoting fun and safety. Much like playground monitors, they pick up on individual behavioral cues — for example, noticing when a dog becomes anxious or has simply been playing for three hours straight and could use a change of pace. Fun can quickly disappear when a dog finds himself in an environment that conf licts with his own emotional state.
The often-overlooked aspect of dog daycare is, of course, learning. “An important factor to consider,” says Laura Monaco Torelli, director of training at Animal Behavior Training Concepts in Chicago, “is that dogs are always learning, even in the daycare environment.” Since most daycares do not explicitly advertise training, owners might not readily notice this aspect. But watch any dog, and you’ll find that various behaviors and emotional states are being reinforced, or not reinforced, over the course of the day by humans, other dogs or even the environment. Just as a toddler might return from preschool with his first painting of a flower and a bit of an attitude, so too might a dog return from daycare played out, but a bit jumpier and mouthier than when he went in.
Some daycares highlight their facilities’ bells and whistles: climate control, dog cams, unique flooring or even a particular type of background music. Unfortunately, many daycare websites are silent on the less flashy ethological and organizational considerations that are most relevant to those concerned about their dogs’ welfare. For example, daycares rarely describe daily play and rest schedules, handling techniques, procedures for introducing new dogs to the group, criteria that determine how dogs are grouped, handler-to-dog ratios, access to outdoor space and staff first-aid training.
There are many ways to handle the daily influx of bouncing dogs, and at their best, daycares do this by viewing every dog as an individual. Some daycares rely on message boards to keep track of the different canine personalities gracing their establishments. Descriptors might read: “Don’t let anyone jump on Tiger’s back. Keep Sam from being overstimulated. Keep Janet from eating rocks or poop.” But how do daycares uncover these nuances?
A behavior assessment is the first step toward getting to know each dog’s unique ethological needs. Even if a dog has been comfortable in comparable settings, there’s no foolproof way to predict how he or she will feel in a novel environment. Each daycare provides a unique stew of sights, smells, sounds, movements and management styles, and any dog could be less than thrilled with the surroundings. Even dogs described by their owners as “social butterflies” or “happy players” do not necessarily thrive in every setting. (I am reminded of a therapy-dog certification class I once observed. The behavior of two of the dogs screamed out, “Umm, may I please be excused from this experience?” Their owners were surprised by their reactions.)
Assessments can also identify dogs who are not likely to be thrilled about daycare from the get-go. For some, discomfort with other dogs could spark aggression; others might be unable to de-stress in a group setting. With this information, daycares can evaluate whether they have the staff knowhow and facility design to admit such dogs. Dog owners not only expect their dogs to be having positive experiences at daycare, they also expect them to be exposed to suitable playmates. “I like that Huey had a behavior test, because that means the other dogs also had a test,” says Beth Windler, a Minnesota dog owner and once-aweek daycare patron. For Windler, this was particularly relevant after Huey, a happy-go-lucky Basset Hound, was injured at a dog park.
The behavior assessment is just the beginning of the story. John Squires, owner and manager of Wag Club in Brooklyn, N.Y., stresses that the daycare facility has an ongoing role in habituating each dog to its setting and rewarding good behavior. He has found that, unfortunately, not all daycares prioritize such methods. Some accept dogs who are completely unsuited for a daycare environment without taking steps to help them acclimate, which could lead to a dog spending most of his time in a kennel rather than interacting with others.
It’s easy to get caught up in procedures and forget about the people. Just as a love of children does not necessarily make someone a competent firstgrade teacher, a love of dogs doesn’t automatically equip a person to manage the behaviors and personalities of a group of them. “Is a daycare just looking for warm bodies who like dogs and can stay there for eight hours a day?” asks Miller. Christensen adds, “Is the staff trained [in] the basics of dog behavior as based on science, not popular wisdom?” Staffers’ ability to recognize stress and discomfort is just as important as their understanding of the complex set of movements that make up play. Play and aggressive displays share many elements, and even to a watchful, astute eye, meanings can change quickly. According to Monaco Torelli, “Observation of canine communication is a critical variable of proactive management in daycares.”
So, is doggie daycare a necessary part of life for every dog? The answer lies largely with the individual dog. Some daycares are better than others at maximizing fun and safety and decreasing fear and stress. At the same time, dog daycare is not the only game in town. Your dog might prefer a long walk, a training class, a trip to the dog park, an open window where he can take in the passing sights and sounds, or a small playgroup. Consider what’s important to and appropriate for your dog. Also consider how you might be able to build time for these extras into your schedule.
When thinking about our dogs’ quality of life, most of us inevitably ask the question, “What should my dog be doing all day while I’m gone?” If you think the answer for your dog involves daycare, then the next question is, “Which one?” A little due diligence on your part will result in a solution that’s right for your pup.

Here is a recap of the study we discussed in Part 1, Oh, hello! Why yes, that's my crotch *:
Crotch factoid #1: A dog enters a room, sees his owner lying on the floor, and he gives considerable attention to his owner's upper body.
Why the difference? Why is a stranger's crotch initially so much more interesting than mine?
Let's first consider why owners' crotches were initially not sniffed. It's possible that dogs do not sniff owners' crotches because owners have taught them not to!
For many humans, crotch sniffing is considered irritating, embarrassing and offensive. Not surprisingly, 1,009 people "like" the facebook page, I Hate Dogs That Sniff My Crotch.
In response, the web suggests ways to prevent crotch sniffing. Some suggest teaching the dog to perform a behavior incompatible with crotch sniffing (such as lying down) and others suggest using words or actions to dissuade the dog from crotch sniffing. Regardless of the training method, it is plausible owners could eliminate crotch sniffing from their dog's owner-directed behavioral repertoire.
At the same time, it seems highly unlikely that an owner would train a dog not to sniff the owner's own crotch, yet allow dogs to continue sniffing strangers' crotches. Since the study under consideration found lots of stranger-directed crotch action, what could be going on?
A better explanation comes from the olfactory content of the human body. We are aware of some of our odors, such as BO, and others evade our consciousness. This is where dogs come in.
Dog + Stranger's Crotch
For dogs, crotch sniffing had nothing to do with getting to third base. Instead, it is more akin to looking over a business card. One of the places we humans keep our business cards is in our crotches, in a set of glands called the apocrine glands. While apocrine glands are found in a number of hairy regions of the human body, they are heavily concentrated in the anogenital (crotch) region. These glands secrete pheromones **, chemicals that enable olfactory communication with others, particularly concerning identity. Investigating a stranger's crotch simply orients a dog to the individuality of that person.
Dog + Owner
Of note: You, the human reading this blog, release volatile organic compounds, or VOCs***. Your breath, for example, contains many VOCs which are both generated by your own body and picked up from the environment at large. In a sense, you are a walking science experiment, picking up odors and producing them on your own, and a dog who knows you is immediately interested in smelling your chemicals.
Whether a stranger to a dog or its owner, we humans are odorous sacks of information, and dogs will sniff many different parts of our bodies. But during an initial interaction with either a known or unknown person, dogs differ in their preliminary points of contact.
This holiday season, will you be sharing your business card with dogs?
Many thanks to Tom Brownlee for always setting me straight when it comes to scent and olfaction.

Part I: Sniffing researched
December 13 2011
The holiday season is in full swing. But before you dive into Aunt Bessie’s famous cookies, you might have to get past a few pinched cheeks and possibly some bad breath.
You know what I'm talking about—from handshakes and hand-kisses, to “man hugs” and double kisses, between now and New Year’s, we humans enter hardcore greeting mode.
Accompanying the acceptable greeting rituals noted above, we also engage in the more discrete variety: the up-and-down glance we get from our sister as we enter the party (I hope she didn’t notice that I’m wearing her bracelet!); the feeling that someone tried to get a look at your shoes without you noticing (of course you noticed). This is what we do. We check each other out.
What about dogs? Come holiday season, any dog who’s a fan of people will most certainly put on his greeting hat. And when dogs are greeting people or checking people out, they tend to go for the crotch. Or do they?
The sniffing investigation
The researchers created a study with two parts. In part one, they observed pet dogs sniffing their owners. In part two, pet dogs sniffed an unknown person. The researchers then studied which human body parts received the most attention from the dogs and their sniffers.
The first thing you are probably wondering: How exactly were people sniffed? (Not something you ask every day.) For the sniffing simulation, the human subjects entered a test room where they lay motionless on the floor with their eyes closed. Once on the floor, the dog entered the room and was observed for five minutes.
To collect the sniffing data, the human body was divided into 10 regions (see below). Researchers could then easily observe where dogs were directing their sniffing. I might add, this mock human has abnormally small feet and nice underwear.
The sniffing report
But there’s more!
Dogs differed in how they sniffed. When it came to sniffing their owners, dogs showed particular interest in the thorax and arms. On the other hand, in the presence of a stranger, dogs focused more on the ano-genital area and thighs. Whether you are more familiar with the terms “privates,” “bits and pieces,” “caboose,” “backdoor,” “flower pot” or “Rocky Mountain Freeway,” no matter how you slice it, dogs were more into sniffing the crotch and thighs of strangers compared to the crotch and thighs of their owners.
For you visual learners, below is a picture detailing the movement of the dog’s muzzle over the body. Top image: sniffing a known person; bottom image: sniffing a stranger. Check out that crotch attention!
So why might your dog get all up in Aunt Bessie’s crotch during the holidays? Simply put, he hasn’t seen her in a year! Maybe if you invited her over for tea more often …
Tune in next time for Part 2: Why is a stranger’s crotch so much more interesting than mine?
