Puppy mill dogs have more behavioral problems
June 21 2017
“We found that across all behaviour categories, including trainability, dogs from less responsible breeders had significantly less favourable behaviour and temperament scores than puppies from responsible breeders.”
The above statement by researcher Catherine Douglas sums up the study “Do puppies from ‘puppy farms’ [puppy mills] show more temperament and behavioural problems than if acquired from other sources?” More extensive results were presented at the annual conference of the British Society of Animal Science.
It was the first study in the UK on the behavior and temperament of adult dogs who came from puppy farms, which we call puppy mills on this side of the Atlantic. Dogs were divided into two categories. One set came from puppy farms or other commercial breeding facilities that did not follow the good practice standards of the RSPCA or the Animal Welfare Foundation’s Puppy Contract (less responsible breeders). The other group in the study was made up of dogs who came from responsible breeders who put a priority on the welfare of the breeding dogs as well as of the puppies (responsible breeders).
Dog guardians filled out surveys about the conditions of the facility the dog came from to determine whether the dog came from a puppy farm (or similar) or from a responsible breeder. They were asked such questions as “Were the puppies raised in a home environment? Did you see the mother? At what age did you get your puppy?” They also filled out a standard survey (the CBARQ, or Canine Behavioral Assessment & Research Questionnaire) to evaluate their dog’s behavior. The breeds studied were the Pug, the Jack Russell Terrier and the Chihuahua.
Though there have been many studies about the physical health of dogs from puppy farms, there is far less research about the adult behavior of these dogs. The results of this study overwhelmingly support the common advice NOT to buy a dog from such a place. In every category, the dogs from less responsible breeders were found to have less desirable behavior than dogs from responsible breeders. Specifically, they were more likely to be aggressive to members of the household, more likely to be aggressive to strangers, more likely to be aggressive to dogs, more likely to be fearful of new objects, more likely to have noise phobias, more likely to suffer from separation anxiety, and less likely to be rated high in trainability.
It’s not clear what factors contribute to these extensive differences in temperament and behavior, but there are many possibilities. Stress during pregnancy can contribute to anxiety in puppies and affect their ability to learn in training. Being separated from the mother while very young can also have detrimental effects on adult behavior. There could also be genetic factors that account for some of the differences between the two groups of dogs.
Though the results of this study are not surprising, they do confirm that where we get our dogs matters. Acquiring dogs from puppy farms supports an industry that lacks proper safeguards for animal welfare and also makes it less likely that your best friend will be the ideal companion and family member that we all want.

Dog clearly communicates his desire to continue walking.
June 15 2017
We were in a rush that morning, and though we felt a little guilty about it, the plan was for the morning walk to be just a 10-to-15-minute quickie around the block. The dogs would just have to wait until later in the day for some real exercise. As we rounded the last corner of our block to head home and begin the work day, Marley put the brakes on and resisted the turn. He stood his ground, facing a different direction than the way we wanted to go. I interpreted his action to mean that he was not yet ready to end the outing. I thought he was conveying the sentiment, “Don’t you dare just go around the block and call it a walk.” My husband’s take was that Marley was thinking, “The walk can’t be over. I haven’t even pooped yet!”
We can only guess what was actually going on in his head, but he was able to communicate quite clearly his desire to walk in the direction that did not lead directly home. Marley is an exceptionally agreeable dog, but he is no pushover. He only infrequently objects to something and is extremely easy going, but once in a while he will assert himself to get what he wants. When he doesn’t want to keep running, he lies down and simply does not continue. When he is cozy in a spot that we want to occupy, he becomes dead weight and is resistant to getting up.
I really like this quality in Marley because it’s nice to know what he wants. He doesn’t often express an opinion, but when he does, he makes his desires quite clear. “I want to walk this way.” “I do not want to move.” “That is enough of a workout for me.” He is not pushy, and I would not describe him as stubborn. He simply has his limits, and expresses them on rare occasions. Most of the time he goes with the flow, being more than up for whatever we have in mind, but he is capable of calmly letting us know his preference.
Do you have a laid back dog who lets you know, every once in a while, that he has a strong opinion about what he wants to happen?

Were your dog’s DNA results just as unbelievable?
June 13 2017
Many members of a local dog group had their dogs’ DNA tested, and one meeting served as the big reveal. Luckily for me, that was the day I had been invited for a Q&A session, because even the introductions were a hoot. Everyone told me their name, and then announced the results of the DNA test of the dog at their feet.
Many of the results were unsurprising. That dog everyone had assumed was a Rottweiler and German Shepherd Cross? Throw in a little Bearded Collie, and that’s just what the test said. The dog that looks exactly like an Irish Setter except that it is black? It is half Lab and half Irish Setter. How about the dog that seemed so impossible to identify that the group couldn’t agree on any likely possibilities? The test came back with breeds nobody had guessed—Plott Hound, Puli, Saint Bernard and Beauceron.
Other results went far beyond surprising and straight into the seemingly impossible. The 90-pound dog that appeared to have some northern breed as its primary source of DNA, but also looked like it had some hound in it? The test said it was half Dachshund, and then a few other small breeds that I can’t remember because the Dachshund part made us laugh so hard it affected our memories. The 25-pound dog that was all white with long hair was reported to be predominantly Portuguese Water Dog with some Great Dane. There was an apparent Terrier mix whose DNA test revealed it to be about half Siberian Husky with some Beagle and a little Shiba Inu.
It’s natural to want to know more about our dog’s genetic heritage, but it’s important to know that these DNA tests are not 100 percent accurate. The evidence suggests that they are not completely reliable, and nobody has been able to validate them to the satisfaction of geneticists. If you want to have your dog tested for fun, that’s fine, but don’t make the mistake of thinking that the results are necessarily a true reflection of your dog’s background. Many people have submitted their dog’s DNA to multiple testing companies and received different answers about the dog’s breeds.
I had a dog whose heritage was a mystery. On some days, I didn’t care, figuring, “All that matters is that he is a dog and I love him.” On other days, I felt a desperate yearning to know what he was, and my thoughts strayed more towards themes of, “It’s my life’s quest. I MUST know what breeds of dogs went into him.” I always described him as “Half Black Lab, Half Handsome Stranger” and if he were still alive, I would most definitely pay to find out what the DNA tests had to say about it.
Even with doubts about their accuracy that require one to take the results with some skepticism, I still love to meet dogs and hear the results of their genetic tests. It’s especially fun when the results are unexpected.
Have you received DNA results about the breeds in your dog and found them, um, unlikely?

Interactions with guardians offer some relief
June 10 2017
Veterinary examinations are stressful for dogs, and being stressed is counterproductive to general well-being. We don’t want our dogs to suffer, especially when the purpose of seeing the veterinarian is to help them. Another issue is that the effects of stress—both the behavioral and physiological responses—can make it harder to examine the dog thoroughly and properly diagnosing the dog becomes harder as well.
A recent study examined the effects of contact with the guardian during veterinary exams on the stress levels of the dog. The basic conclusion of the study was that it is beneficial to dogs for their guardians to interact with them with physical contact and verbal communication. Dogs were less stressed by several measures when their guardians interacted with them compared with just having their guardian present in the room.
Every dog was studied during two visits to the veterinarian—one in which the guardian talked to and had physical contact with the dog, and one in which the guardian was present in the room but did not interact with the dog. The canine behaviors observed were panting, vocalizing, attempting to jump off the exam table, struggling, lip licking, yawning and paw lifting. The physiological measures were heart rate, cortisol levels, maximum ocular surface temperature and rectal temperature. All behaviors and physiological measures are associated with stress in dogs.
When guardians were allowed to talk to and pet their dogs (the “contact” condition), the dogs attempted to jump off the table less often and vocalized less than dogs whose guardians were present but not interacting with the dog (the “non-contact” condition). There were no differences in any of the other stress-related behaviors. On the physiological side, dogs in the “contact” condition did not have as large an increase in heart rate or maximum ocular surface temperature as the dogs in the “non-contact” condition did. There were no differences between the two conditions in rectal temperature.
This study offers some encouragement about our ability to make a difference to our dogs’ stress levels when at the veterinarian. The results suggest that interactions with the guardian may be more effective than just the physical presence of the guardian, but the effect is not striking. By many measures, there were no differences. The behavioral measure that did differ—vocalizing and trying to jump off the exam table—may do so because both of those behaviors could be an attempt to make contact with the guardian. Dogs do often vocalize as a response to separation, and dogs who try to jump off the exam table may sometimes do so as an attempt to make contact with their guardians.

Let’s celebrate dogs like Lassie instead of like Marley
June 7 2017
There’s no doubt that a certain amount of impishness can be delightful, and it’s easy to be amused by it. For example, many people have understandably laughed at Marley’s escapades in the book or the movie he inspired. Yet, I think it is really important to keep in mind that what we are laughing at—destructiveness, pulling on the leash, eating jewelry, greeting people by putting paws on their shoulders and running away—is actually straight-up undesirable behavior.
It has become increasingly common in the dog world to excuse ill-mannered dogs who lack any kind of training skills by saying they are just like Marley. It’s as though that validates the behavior, making it not just acceptable, but enchanting. Often, guardians who use this excuse could improve the dog’s behavior with some effort and education, but they don’t bother. Instead, they seem to find any obnoxious (or even dangerous) behavior hysterical. It’s an unfortunate cultural development to value behavior stemming from bad manners and a lack of training. Regrettably, it is has become some kind of competition about whose dog is the worst and most incorrigible, to the point that many people aspire to having a dog who acts “like Marley”.
It’s not that I expect dogs to be perfect or that I expect guardians to act as professional trainers in all their free time or raise a model dog. I’ve seen plenty of dogs do things that I wish they wouldn’t and understand all too well how hard it is to teach dogs to be polite canine citizens. I also get that although many dogs are generally good and can learn to be reasonably calm and well-behaved with even a little training, it is much harder for some dogs. There are plenty of dogs who have impulse control issues, and whose natural behavior doesn’t lend itself to high praise. That doesn’t bother me, and I enjoy dogs who struggle to be their very best selves as well as dogs who are naturally easy keepers. Marley was the most rambunctious puppy in the litter and suffered an extreme fear of thunderstorms, so it’s unfair for anyone to claim that Marley’s issues could have been resolved with simple training. It’s also true that more training would have helped.
Although absurd situations based on dreadful behavior are bound to happen, we shouldn’t accept such incidents as the best and most fun part of life with dogs. The occasional story of generally nice dog having an “oops” moment can certainly provide a good laugh. It’s normal to tell tales that begin, “Well, there was this one time. . .” What’s not normal is having all the stories about a dog be about something horrible. Such stories should be the exception rather than the descriptions of a dog’s day-to-day actions.
Sure, if a dog runs into the clothesline one time and races through the neighborhood in a panic dragging towels across everyone’s gardens, that can become a good story. However, if there are a dozen stories from the last month or so about similar incidents, that’s a problem. If your neighbors all think, “Oh, no! What now?” when they see your dog—once again—off leash, out of control and being destructive, it should be more alarming than funny to all of us.. There is a high risk of harm to dogs who bolt out the front door, ingest inedible items or destroy household objects, among other “bad” behaviors.
I object to the glorification of impolite, out-of-control behavior, and celebrating the most devilish aspects of our canine friends. It can be tiresome to have people find it endlessly charming when dogs are not trained and have bad manners, especially when the humor aspect is used as an excuse not to teach their dog how to behave in an acceptable manner. The Bark Magazine co-founder and editor-in-chief Claudia Kawczynska receives many submissions about “dogs who are worse than Marley” and detailing situations the people invariably call hilarious. It’s common for people to describe the incidents as being scenarios much like those Marley got himself into, but point out that the dog in this story is “even worse” than Marley. Many of these pitches reveal guardians who are uninterested in training and have no knowledge of how to teach their dogs anything, including basic manners. The result is a lot of untrained and ill-mannered dogs doing things that aren’t funny at all. In part because of the success of Marley and Me—both the book and the movie—dreadful behavior has not just been excused, but celebrated.
I wish good canine manners were more interesting to people than bad canine manners, the occasional story of mischief by a generally well-behaved dog notwithstanding. I’d like to see more people brag about their dog’s stay, their new trick, how they greet visitors, or any other example of training and good social skills rather than about problem behavior. It may very well be the dog trainer in me, but I remain hopeful that there are a lot of us out there who are more charmed by good behavior and good manners than by bad behavior and bad manners.
Good Dog: Studies & Research
June 2 2017
“Calming signals” is a term coined by Norwegian dog trainer Turid Rugaas to group a large number of behavior patterns that she says dogs use to avoid conflict, to prevent aggression, to calm other dogs down and to communicate information to other dogs and to people. Since the publication of Rugaas’ 2006 book On Talking Terms With Dogs: Calming Signals, it has been a popular idea that actions such as lip-licking, sniffing the ground, yawning, scratching, looking away, play bowing, sitting down, lying down, softening the eyes, blinking and even sneezing (along with many others) are social signals that help calm down those around them.
Rugaas’ observations are compelling, and many dog trainers and behaviorists, including me, have learned a lot from her work. However, the term “calming signals” entered the lexicon without much analysis, which is problematic. Using a term that ascribes functionality to behavior patterns prior to scientifically testing whether or not that’s true creates challenges, and is a big no-no in ethology. One problem is that claiming that certain behaviors are “calming signals” creates a bias such that people tend to accept that this is, in fact, what they do. The idea that these signals are functioning in this way is an intriguing hypothesis. However, in the years since Rugaas shared her ideas with the dog community, there have yet to be adequate tests of their function, or substantial efforts to determine if the various behaviors have different functions. Rather, the idea that they were calming signals was broadly accepted without being subject to rigorous scientific study.
There is, however, a recent pilot study investigating the function of the behavior patterns that have all been placed into the category of calming signals. The purpose of the study “Analysis of the intraspecific visual communication in the domestic dog (Canis familiaris): A pilot study on the case of calming signals” was to assess if the behaviors that have been called calming signals are used to communicate, and if they de-escalate potentially aggressive situations between dogs. In the study, 24 dogs were observed interacting two at a time. Dogs interacted with familiar and unfamiliar dogs of both sexes.
Throughout the course of the study, 2130 calming signals were observed, with the most common being head turning, nose licking, freezing and turning away. Dogs were more likely to display calming signals when they were interacting with the other dog compared with when they were not interacting, which does suggest a communicative role. It does not prove it, though, as it is possible that these behaviors indicate stress and that they are performed during social interactions more often than they are performed outside of that context because such interactions are stressful. In fact, most of the signals that Rugaas has called “calming signals” are also considered indicators of stress.
More calming signals were displayed when dogs were interacting closely (within 1.5 body lengths of the dog displaying) than when interacting at a greater distance. Overall, more calming signals were exhibited during interactions with unfamiliar dogs than with familiar dogs, but licking the other dog’s mouth was more frequently observed when the other dog was familiar.
During the interactions in the study, there were 109 instances of aggressive behavior. A calming signal never came right before the aggressive behavior, but 67% of the time, at least one calming signal followed the aggressive behavior. In over 79% of the instances in which a calming signal followed the start of the aggression, there was a de-escalation in the aggressive behavior. These data are consistent with the idea that these behaviors function to calm other dogs down and lessen their aggression, but the work is too preliminary to conclude this for certain. More research is needed to explore other possibilities, such as the role of stress in these behaviors and their effects, and the potentially different functions of each of the dozens of behaviors that have been lumped under the term “calming signals”.
This is a pilot (or preliminary) study, and though the results are intriguing, they are in no way a definitive test of the function of “calming signals” in dogs, which the authors correctly point out in their paper. Though this research makes an attempt to test the often-accepted hypothesis that many behavior patterns function as calming signals that de-escalate aggression, its biggest flaw is that it lacks a very important control. De-escalation of aggression is quite common, and in this study, the authors report the frequency of de-escalation after a calming signal, but do not report on the rate of de-escalation in the absence of a calming signal. Part of the problem is that with so many possible calming signals, it is quite likely that one will be exhibited as a response to aggression. (Dogs are unlikely to have no reaction to such behavior.)
To evaluate the function of the behaviors, it is necessary to know the frequency with which the aggression de-escalates in the absence of any calming signals. We know that there was often de-escalation in the absence of calming signals because the authors report that in quite a few cases, the dog on the receiving end of the aggression walked or ran away, increasing the distance between the two dogs, which was often associated with a de-escalation in aggression. Fleeing is not considered a calming signal, and yet when the distance increased between the two dogs, there was also usually a de-escalation of the aggression. Future research should explore the differences in behavior in cases in which there was de-escalation and in which there was not.

Enhancing the neighborhood one house at a time
May 30 2017
I love my neighborhood because it is unpretentious, the wide streets have sidewalks and it’s full of dog lovers. Besides the large number of dogs out on walks, the most obvious sign of that is the popularity of dog-themed welcome mats. My favorite is the one that says, “We’re so excited to see you we don’t know whether to pee on the floor or tear up the couch,” though the classic “Wipe Your Paws” is a close second.
My next door neighbors recently purchased the fashionable, “Ask not for whom the dog barks, it barks for thee.” Around the corner I just saw a doormat that reads, “Please remove your shoes. The dog needs something to chew on.” I got a chuckle when I visited a neighbor who was just putting out a new mat that reflects the state of things in her house: “Our dog flunked out of obedience school. He’s back, living here at home.” I laughed a little harder when she told me that she almost bought the one that said, “Ring the doorbell and let me sing you the song of my people. –The Dog”.
We’ve come a long way since the only dog-related expression one saw outside of someone’s door was “Beware of Dog”. Today, you are far more likely to see a welcome mat that says, “We like big mutts and we cannot lie” or “It’s all fun and games until someone ends up in a cone.” It’s quite common to welcome people into a house with a mat that says, “Welcome Diversity” and features a graphic with dogs of different shapes and sizes. Another option I’ve seen multiple times is the one that lets people know the inhabitants value “Peace, Love & Muddy Paws”.
Does your welcome mat pay homage to the canine members of your family?

People on live TV forced to roll with it
May 27 2017
Dogs occasionally end up on the air during live newscasts and the people on screen have to make the best of it. In this Russian broadcast, it does not appear as though the anchorwoman is too thrilled. She sounds alarmed but tries to make the best of it, even petting the dog. However, she looks startled when he jumps up on the news desk and messes with her notes. According to the description of the video, she says, “This is why I like cats.”
The weatherman in the next video acts more like a dog lover, responding in a generally relaxed and dog savvy way to sharing the screen with a canine. This man easily throws the toy with both his left hand and his right, and knows that the fake throw is a good move when the dog fails to see the actual toss. He adjusts well to simultaneously playing fetch with the dog who joined him and continuing with the weather forecast, even making a joke about men not usually being able to multi-task.
In this last video, the weatherman purposely had the dog on air with him, but he definitely should have heeded the common advice to avoid screen time with children or dogs. The risk of them stealing the scene is ever-present! In this case, the dog was a visitor from a local humane society, and a high energy, mouthy adolescent more skilled at play than basic manners. In the first 30 seconds of the clip, the dog chewed through his leash, leapt up on the man four times, and engaged in a vigorous game of tug with what was left of the leash. This poor man was completely distracted, and looked a bit foolish as the dog got the better of him. To be fair, he didn’t let it get him down. He was laughing—apparently enjoying the dog and his antics.
There’s a certain spirit of adventure when it comes to live TV, and these dogs are proof that you never know what is going to happen!

People are able to interpret these vocalizations
May 23 2017
Research in recent years has shown that our brains can process the emotional content of vocalizations based on acoustic structure, and that various mammalian species share the same brain structures used for such interpretation. That means that we ought to be able to interpret the emotional nature of vocalizations from other species much like we understand those of other people.
Multiple studies of communication across species have found that animals can understand the emotional nature of vocalizations made by members of other species. In a number of studies, experience with the other species enhanced the ability to understand calls from that species.
Cross-species communication is particularly interesting between humans and dogs because of the long history we have of associating with one another, leading to the possibility that we have influenced each other’s vocalizations. In order to investigate people’s ability to understand canine growls, researchers conducted a study in which people listened to recordings of dogs growling and were then asked questions about the emotional state of the dogs.
In the study, “Dog growls express various contextual and affective content for human listeners”, 40 people heard recordings of growling dogs. All of the growls were recording in one of three contexts: guarding food from another dog, playing tug with a person and being approached by a stranger. In the first part of the experiment, the people were asked to rate each growl on a sliding scale for each of the following emotions: fear, aggression, despair, happiness and playfulness.
The emotional profiles based on the 40 ratings of all three contexts were different. Food guarding had the highest aggression rating, followed by the stranger context, and the growls from play had the lowest aggression scores. For the other emotional states, the food guarding and stranger context did not differ from each other, but were rated higher in despair and fear than the playful growls and lower in playfulness and happiness than the growls recorded in play.
In the second test, people were asked in which of those three situations the growl was recorded. Overall, people correctly identified the context of 63% of the growls, which is significantly better than the 33% rate that chance predicts. The play growls were most readily identified, with 81% of them being correctly chosen. The food guarding growls were correctly identified 60% of the time, compared with 50% of the growls directed at strangers. Most of the errors in identifying these two (potentially aggressive) contexts involved confusion between the two of them, rather than with the playful context.
The authors conclude from this study that people can distinguish different types of dog growls, including being able to tell apart growls that are both in potentially aggressive contexts. Previous studies have found that people’s ability to understand canine growls is influenced by the time between growls and the duration of the growls. Based on analysis of the acoustic structure of the growls in this study, the key characters of the growls that make them seem different to people are the rhythm of the series of growls and the length of the individual growls within that sequence. Longer gaps between growls is associated with higher aggression scores. Shorter growls are generally perceived as more positive on emotional scales. In growls recorded in the context of a stranger approaching, the higher the pitch of the growl, the higher the fearfulness score.
Individual people varied in their ability to identify the context of the growls. Overall, women were better at it then men. Also dog guardians outperformed people who do not have dogs. Whether or not a person had ever been bitten by a dog had no effect on whether people were able to determine the context of a growl. This study shows that although people in general can interpret the emotion in canine growls, experience plays a role in how well they are able to do so.

Husky’s future home to be decided by the courts
May 17 2017
Microchipping dogs is a great tool for reuniting people and dogs, but only if people do the responsible thing and check dogs that they find for the presence of a chip. That didn’t happen in the case of a Husky who is now at the center of a lawsuit to decide who gets to keep the dog.
In 2010, Michael Gehrke bought the dog who he named Mya. She lived on his 10-acre property with his horses and two other dogs. Mya was best buddies with one of them, Rex, and the pair had two litters of puppies together. In 2013, she wandered off and Gehrke’s attempts to find her by posting signs and visiting the local shelter were unsuccessful.
Mya had walked to the local elementary school. Instead of checking her for a microchip or attempting to find her family through any other channels, a staff member at the school passed her on to her son’s friend, Ashlee Anderson. Anderson had just moved from the town where Gehrke and Mya lived to a town 200 miles away, and was in the market for a dog.
In 2017, the dog (who Anderson calls Sitka) wandered off again and was picked up by animal control. Because she wasn’t wearing any tags, the animal control officer checked her for a microchip, which identified her as Gehrke’s dog Mya. Gehrke assumed that since she was traced to him, and he showed all his vet records and photos of Mya as a puppy, that he would get his dog back, but that is not what happened.
Instead, the animal control officer returned the dog to Anderson. Her rationale was that there was no evidence of a crime and that her job is not to act as a judge but to get dogs off the streets and back to a safe home. Gehrke has filed a lawsuit in order to require that Anderson return the dog.
Anderson offered to pay Gehrke $1,200 (his original purchase price for Mya) to keep the dog, but he informed her that he is not interested in the money. So Anderson has responded by hiring attorneys to argue her case so she can keep Sitka.
A judge will hear the case on June 2, 2017. Both people clearly love this dog, so whatever happens, she will end up in a loving home. However, one of the people—Gehrke or Anderson—will be saddened by a legal decision that means they must live without her. All of this mess, including the impending heartbreak for a person who loves this dog, could have been avoided if Mya had been checked for a microchip the first time she wandered off.
Who do you think should end up with the dog?
