New product reacts to your mood
September 25 2012
Tail envy may not be the talk of many psychiatric conversations, but there’s a new product to deal with it, anyway. The company Neurowear has created a tail that responds to a person’s emotional state. This clip on tail is called “Shippo” and moves as your mood dictates. If you are happy or excited, it will wag, but if you are calm and contemplative, the tail simply hangs down.
Shippo uses the same technology that medical equipment utilizes in the measurement of brain activity, including the patterns that indicate seizures. With a sensor on the forehead to measure electricity, a clip on the ear to detect the pulse, a motor in the tail itself, and communication between the sensors and the tail via Bluetooth, it’s a pretty complex toy.
They may not make important medical devices that save lives, but Neurowear’s creative use of technology can do a lot for our quality of life. Who among the dog-loving population has not wished to have a tail, at least every once in a while? If I had the choice, I would love to have a Great Dane’s type of tail. I have such fond memories of childhood when the otherwise gentle Danes I loved would clear a coffee table of everything with one casual wag. It always made me laugh.
What kind of tail would you choose?

Is your dog hard to tire out?
September 21 2012
I picked my kids up from the climbing gym a few weeks ago after they had spent an hour and a half there. It’s great exercise—physically demanding both aerobically and from a strength perspective—and many parents claim that their kids sleep really well afterwards. Not mine. They just don’t seem to tire out easily at all, and the fitter they become, the harder it is to wear them out. The instructor actually said to me on this occasion, “They’re pretty energetic still. I don’t know what to tell you. We tried to tire them out, but they could probably climb for several more hours.” To be clear, they were not misbehaving, but neither were they worn out.
Many dogs are like my kids in that they are not easily exhausted. In fact, for many dogs, the exercise that we typically give them—a long leash walk—doesn’t tire them out at all. It invigorates them. It’s discouraging to consider that when we take our dogs out for a walk, we may not be tiring some of them out, but rather, pepping them up. That’s certainly what a brisk walk does for me. A run, especially a hard run or a really long one does exhaust me, but a walk does not. My kids are even harder to tire out. Like many dogs, the only way to truly tire them out is to spend a lot of time in the ocean or a lake. The sun and swimming can accomplish what more typical forms of exercise can’t.
It’s a great feeling to be tired, worn out, and ready for a relaxing evening followed by a good night’s sleep. It’s a great kindness to provide our dogs with that same experience. However, it’s not as easy with some individuals as with others. Some dogs are suitably tired out by long leash walks, but others require hours of off-leash running at high speeds or long play sessions romping with other dogs to have their exercise needs satisfied.
Do you have a dog who seems to perk up from 30 to 60 minutes of exercise and really needs a lot more activity? What does it take for your dog to be happily tired?

From the Philippines to California for surgery
September 17 2012
A dog in need of surgery is about to travel from her home in the Philippines to the United States for the medical care that’s not available where she is. Kabang has had a life filled with more adventures than most dogs. Her name means “spotty” in her family’s native language, and though that probably refers to her appearance, it certainly applies to her luck as well.
She was found as an abandoned puppy two years ago by Rudy Bunggal. Since his family struggles to acquire enough food, there was a very real possibility that she would find her way to their dinner table. Instead, though the Bunggals continue to face food shortages, Kabang remains a cherished pet who is closely bonded to Rudy’s daughter Dina and his niece Princess, and protective of them as well.
Her protective tendencies made this dog a national hero when she charged in front of a motorcycle that nearly hit Dina and Princess. The girls and the motorcyclist were merely bruised in the incident, but Kabang was not so lucky. Her face was caught in the spokes of the motorcycle, causing her to sustain terrible injuries. The accident, which saved the lives of two members of her family, resulted in the loss of a large part of her face.
After the accident, Kabang disappeared and she was feared dead until she showed up weeks later at home. It was at this time that her story made national and international headlines. Local veterinarians offered to euthanize her, but the Bunggals refused to allow it. Although she is not believed to be in pain currently, her injuries leave her susceptible to infection, and surgery is necessary to keep her healthy.
Surgery is expensive, though, especially when the care she needs is not available locally. Having heard about Kabang, a woman in New York set up the site careforkabang.com in order to raise money, and also convinced Philippine Airlines to donate the ticket to fly the dog and his guardian to the United States. The goal to raise $20,000 was recently reached, and Kabang will soon be headed to UC Davis for surgery. The reconstruction is an attempt to regain enough function in Kabang’s face that she can continue to be a happy, healthy family pet. She will still look very different than she did before the accident, no matter how successful the surgery is.
The world joined in to help this dog. To Kabang and her family, the help of many strangers will make a world of difference.

Combined skills allow food raid
September 14 2012
Though many cats and dogs are very dear friends, others simply coexist or even fight to varying degrees. It’s fair to say that they are not always on the same team. That’s why I find it so endearing when dogs and cats cooperate to work towards a common goal, even if it’s to get into trouble together.
The most common example I hear from friends and clients is about these two species combining their skills to acquire food. Cats are easily able to jump up onto counters that the dogs in their households can’t reach, but once they are up there, may be unable to break into any containers of food they find. Pushing bags of food onto the floor where the dogs can tear into them is one strategy, and it’s not that rare.
Has your household experienced such division of labor—the cat tipping a bag of food off the counter and the dog opening it so both can feast on it? Do you have other stories featuring dogs and cats who are in cahoots together?

Does size affect behavior?
September 13 2012
He chose the dog, but I chose the name,” the woman explained. Their dog was an especially petite Boston Terrier, but his name — Titan — was one more typically bestowed on a larger dog. I’d seen this type of incongruity before, and though it’s sometimes just for the sake of being ironic, often it’s about conflict. Couples who disagree about whether to add a large dog or a small dog to their family compromise by choosing a dog of one size and a name that’s usually given to a dog of another size. I’ve also met Pixie the Newfoundland, Tank the Bichon Frise, Bitsy the Bouvier and Goliath the Pug.
People often have strong opinions about what size dog best suits them. Some prefer small dogs because they’re more likely to be welcome everywhere, especially when traveling, while others gravitate to large dogs because they associate them with fun and friendliness, as well as kids and families. Sizebased biases are also common, and sad to say, I’ve heard a number of derogatory terms for both small and large dogs. And anyone with big dogs knows that people sometimes fear them even when their behavior is exemplary and a small dog is present whose behavior is not. One Bark reader implored me, “Don’t forget to cover that big dog stigma!”
Many people have asked the question, “How is the experience of having a large dog different than that of having a small dog?” Part of the answer may come from evaluating whether big and small dogs really are different in ways that extend beyond size, particularly in their behavior. Another piece of the puzzle involves determining if people’s behavior toward and expectations of dogs varies based on the dog’s size.
A Sizeable Spectrum
People with little dogs who don’t want them to help themselves to food simply avoid picnicking on the floor and are careful not to leave chairs where they can be used as stepping stones to the table or counter. People with large dogs often find that no place lower than the top of the refrigerator is safe or truly off-limits. With a large dog, the accidental consumption of dangerous foods, such as chocolate, is far less likely to lead to serious consequences than for a smaller dog because it takes much more for the dose to be toxic to a larger dog. Similarly, the few extra treats that lead to weight gain in smaller dogs may be no big deal for a large dog. Finally, helping a large dog with mobility issues can be physically demanding for the caregiver.
Some worry about big dogs around children, but I must confess that I worry when we dog-sit a friend’s sixpound Pomeranian. My kids are gentle with him and do a good job of being kind and respectful, but I’m still worried that they’ll collide with him and cause an injury completely by accident, no matter how actively I’m supervising. With bigger dogs, that isn’t as much of a concern.
Many people point out the advantages of small dogs in urban environments: it’s easier to rent an apartment (weight limits favor them); tight living spaces may be easier to share; and getting small dogs into and out of an apartment building, especially while you’re housetraining them, is far less of a challenge. Yet traits that can be troublesome for urban living — high exercise needs, sound sensitivity, a tendency to bark excessively — have nothing to do with size. Some dogs are beautifully suited to life in the city, and others are not.
So, are behavioral differences sizebased? For the most part, the answer is a resounding “No!” Dogs of all sizes love to play chase, fetch, go on walks, run off leash, meet new people, romp with their best dog buddies, participate in training sessions and eat tasty treats. By the same token, dogs of all sizes are vulnerable to sound sensitivity, exhibit separation anxiety and aggression, jump on people inappropriately, bark to excess, chew on shoes, dig in the garden, or have accidents on the floor. They all wag their tails (if they have them!) in joy.
And yet, there are clearly differences between individual dogs, based perhaps on age, gender or the environment in which the dog lives and was raised. While the similarities in dogs of different sizes are far greater than the differences, can we deny those differences?
Science Steps In
The study’s most important overall finding? There are significant differences in behavior between large and small dogs and between guardians of large and small dogs. The researchers reported that a range of interactions between people and their dogs are related to the size of the dog.
Small dogs were reported to be less obedient, slightly more often aggressive or excitable, and more anxious and fearful. People with small dogs also reported a lower level of consistency in their interactions and enforcement of rules than did those with larger pups.
Much has been made of the practice of treating small dogs like babies, though it’s hardly surprising that it occurs. Babyish features affect human caretaking behavior; we’re evolutionarily hardwired to find big eyes, small size and proportionally large heads endearing. Psychologists call this the “Aww phenomenon.” If babies weren’t so cute, parents could be less likely to respond to their needs, and the offspring would be less likely to survive.
Dogs seem to elicit this same “aww” response in humans, especially small dogs, and even more so, breeds with pronounced juvenile features such as Cavalier King Charles Spaniels, Chihuahuas, Japanese Chins, Pugs and Boston Terriers. Since babies affect our hormones, raising the levels of oxytocin — nicknamed “the love hormone”— it stands to reason that adorable dogs do, too.
Socialization, Training and Other Interactions
Many say that their small dogs are “people” dogs and don’t like other dogs; lots of people with big dogs say the same thing. Size notwithstanding, positive experiences with other dogs during puppyhood are the best way for a dog to develop good manners. Absent enough of those experiences, dogs of all sizes face social challenges.
Well-trained dogs are always a joy, but training is another way in which interactions between people and dogs differ based on size. Two research studies found that small dogs do not receive as much formal training as large dogs (Kobelt, et al.; Masters and McGreevy). Also, people play fetch more often and do more tugging and nose work with big dogs than with small ones, and are more likely to take them running or biking (Arhant, et al.). Arhant’s study concludes that differences in people’s behavior may account for the higher rates of disobedience in small dogs.
Codes of Conduct
For example, small dogs are more likely to be allowed in our beds and on our laps (Westgarth, et al.). Practical considerations are at work here. Having a 25-pound dog jump or sit on you is one thing, but having a 100-pound dog do it is another. Others encourage little dogs to jump up on people and get on the furniture, but rarely invite big dogs to do so. Jumping up isn’t the only thing that’s treated differently. The behavior that is considered a nuisance in a small dog may be deemed antisocial in a large dog. Even aggression and other serious behavioral issues are more likely to be tolerated in small dogs.
As evidence that some people with small dogs don’t take undesirable behavior seriously, consider this story: an eight-pound Chihuahua escaped from his home, bit someone and was declared a dangerous dog. When a representative from animal control came, the dog’s people apparently thought it was a joke. One of them was reported to have said, “I broke out laughing. I said, ‘Look at the dog, do you see the dog going after you?’ The guy kind of got upset when I started laughing at him.”
For years, I have specialized in cases involving aggressive dogs, and to be honest, the size of the dog sometimes makes a difference in how I feel about the threat they represent. I once had a very aggressive Dachshund in my office, followed by a Chesapeake Bay Retriever with similar issues. During both appointments, I employed all the cautions necessary in this line of work. Still, throughout the appointment with the Chessie, I was aware of being afraid, while with the Doxie — though I knew I was at risk of being bitten if I made a mistake — I just didn’t feel the same anxiety. Both dogs were equally aggressive, but the size factor affected my fear response.
I’m not alone in reacting differently to aggressive dogs based on their size. Large dogs are more likely to be euthanized for aggression (Reisner, et al.), though another study (Guy, et al.) found that the average “biter” tended to be a smaller dog. It’s possible that greater tolerance for this behavior in small dogs allows genetic tendencies toward it to persist.
In some ways, there are correlations between size and breed characteristics. Many small dogs are terriers and earthdogs, types that have been deliberately developed to be tenacious and curious as well as to dig and explore. If dogs are bred for those characteristics, such behavior will have far more to do with genetic inf luences on behavior than with size.
Also related to breeding, Arhant, et al. found that small dogs were more likely than large dogs to come from pet stores, which generally acquire their “stock” from puppy mills. When you consider that puppy mills are notorious for environmental deprivation and risky breeding practices, it is perhaps no surprise that small dogs are burdened with more problematic behavior..
. . . . . . . . . . . . . .
What dogs do — their behavior! — is what makes them good company, great friends and essential members of our family, and very little of that has anything to do with size. When dog people swap stories, they are not about the size of the dog, but about the experiences we have in common — the joy, the angst, the training, the vet emergencies, the photos, the occasional chewed shoe, the games, the walks, the friendship, the fun and the love. It’s always a big love, no matter what size the dog.

The science behind the behavior
September 11 2012
I had always assumed that dogs shake vigorously after a bath or a swim in order to share massive quantities of water with all people in the immediate vicinity. That hypothesis fits in with my philosophical view that dogs have a generosity of spirit that knows no bounds and that they love us very much. It also matches my personal experience as a dog groomer and as a dog guardian.
A recent study takes a far more scientific approach to this behavior. Mammals that are wet suffer the risk of hypothermia, so water removal is a serious issue. Animals who remain wet can use 20 percent of their daily energy staying warm and generating the heat necessary for evaporation of that water. If an animal can quickly and efficiently remove excess water, they will dry faster, suffering less risk from the cold and saving energy.
In “Wet mammals shake at tuned frequencies to dry”, Andrew Dickerson, Zachary Mills, and David Hu enlighten us about the specifics of shaking. They studied the water removal affects of shaking behavior in animals ranging in size from mice to bears, and including dogs.
These researchers observed mammals shaking themselves when wet and came to several conclusions. One is that there is a mathematical relationship between the size of the animal and the frequency with which they shake. The smaller an animal is, the more water they take on relative to body weight, and the faster they shake to remove that water. Smaller animals shake faster (at a rate of 29 oscillations per second for mice) while larger animals shake more slowly (4 oscillations per second for bears.) As animals in the middle of the size range studied, dogs had an intermediate rate of 5-7 oscillations per second depending on the size of the dog. The dogs in the study included members of various breeds: poodle, Labrador retriever, chow, Siberian Husky and Chihuahua.
Another conclusion of the researchers is that the ability of mammals to remove water relates to a property of their skin—its looseness. The amplitude of the shake is increased by loose skin. Though the rotation of the spinal column only reaches 30 degrees, the skin movement allows a total rotation of up to 90 degrees. Loose skin in mammals has previously been hypothesized to help with limb movement but this study suggests another function—extra movement in shaking that allows additional water removal.
If you’ve ever been near a wet dog shaking, it will come as no surprise at that dogs, as well as other mammals, can remove about 70 percent of the water from their fur with just a few seconds of shaking. The effectiveness of shaking behavior is extraordinary, though I must confess that I rarely appreciate it when I experience it at close range.

No tools can do what she can
September 6 2012
It really should come as no surprise that a dog can be trained to find bones. In fact, it’s hard to think of a job better suited to them. Yet, Migaloo the Black Lab is believed by her guardians to be the first dog who has been specifically trained to find buried human bones at archaeological sites. Trained cadaver dogs have previously discovered human bones that were nearly 200 years old, though they were not specifically trained to do so.
Migaloo was trained to alert to skeletal remains with the use of a 250-year old human skeleton on loan from a museum. It took six months of training, field trials and search tests to turn her into an archaeologist. Now Migaloo can do what no humans can do, even with the assistance of radar, magnetic technology and help from historical records. She can find ancient humans bones with high reliability due to their distinct odor. It’s unclear what that odor is and many people are surprised that there is a specific odor. Perhaps that’s why some people didn’t think dogs would succeed in this sort of work.
But Migaloo has succeeded, finding human bones over 600 years old that she was able to detect at a depth of two meters. Her job is to work at sacred Aboriginal sites in Australia finding skeletal remains. Her knowledge can be used either to find places to excavate or to find and protect burial sites. Perhaps soon there will be other dogs working at sites around the world at sites of ancient civilizations.
Migaloo is rewarded for her work not with a bone of her own, but with a game of fetch.

Puppies are named after them
September 4 2012
After September 11, 2001, more explosives detection dogs were trained to work in airports and other areas of mass transportation all over the country. To honor those people who lost their lives on that day, the Transportation Security Administration began naming the dogs in their puppy program after them.
Lisa Dolan’s husband, U.S. Navy Captain Bob Dolan, was one of the people who died at the Pentagon. When Lisa met Dolan, a Labrador Retriever puppy named in his honor, she said that it felt like she was hugging her husband. He gave her great comfort. Can there be any nicer gift to give a widow?
And it was surely an emotional moment when the family of fallen firefighter Carl Asaro met the dog named Asaro. The two-year old dog was trained as a bomb-sniffing dog and was recently put up for adoption. His new guardian went to great lengths to meet Asaro’s wife and three sons.
Dolan was born over a year ago, and he was the 500th puppy in the program. A lot of people who died on September 11, 2001 have had a puppy named after them, but sadly, there are many more who have yet to be honored in this way.

Unusual pairings happen
August 31 2012
When I said that she looked like a Pit Bull Chihuahua cross, I didn’t really think that’s what she was. Though our whole family thought that’s what she looked like when she showed up in our driveway, we also thought that such a mating was unlikely.
It didn’t matter much to us—we just enjoyed her for who she was—a delightful dog who was energetic, expressive, friendly, bouncy, and very licky. None of us cared that much about her heritage, but it’s always fun to guess what breeds are in a dog.
When we did ask her guardian if he knew what kind of dog she was, he replied. “You’re probably not going to believe this, but she’s a Pit Bull and Chihuahua.” They had neighbors who each bred one of the breeds, and she was from an accidental litter. (The Pit Bull was the female in case you were curious.)
Do you know of any particularly unexpected crosses, whether they were a result of a “whoops” litter or not?

It’s an awkward social situation
August 27 2012
A friend of mine was telling me that when her sister-in-law comes to visit, it can be very uncomfortable because that sister-in-law really hates dogs. She voices a lot of criticism of the cleanliness of houses with dogs and the fact that so much time is wasted cleaning up after dogs, which my friend naturally finds annoying. To her, the dogs are family and the extra effort to keep the house clean is worth it. (By the way, I have been in this friend’s house and I consider it immaculate! I’ve been in houses that have a little too much dog hair and eau de dog aroma even for my taste and this house is nothing like that.)
It’s perfectly reasonable to tell potential visitors that if they don’t want to be around dogs, they are more than welcome to stay in a hotel and that you’d be happy to help them find a conveniently located one that is to their liking. However, we all know that family dynamics can sometime make this option very sticky. Being asked to kennel your dogs or keep them locked in the backyard or in one room are all requests that have been received by various friends or colleagues of mine from assertive relatives.
The simple reply that the dogs are part of the family and as such as not shut away or sent away, no matter how tactfully stated, is likely to upset the sort of people who would make such demands in the first place. It’s hard to explain how much we value our dogs to someone who just doesn’t get it.
If you’ve faced a situation with visitors who don’t love dogs and expect you to remove your dogs from the situation, how have you handled it?
