GI Involvement in Behaviorial Issues
Some Compulsive Disorders Point to the Gut
Dog looking away

Canine compulsive disorders (CCDs) take many forms and are generally considered to be behavioral issues. However, recent studies suggest that at least two of them—“excessive licking of surfaces” (ELS) and “fly-biting syndrome,” in which a dog appears to stare at something and suddenly snaps at it—may be related to underlying health issues. Both studies were conducted by researchers associated with the University of Montréal Veterinary Teaching Hospital.

The first set out to investigate surface-licking behaviors to see if there was a medical component: “The objectives of our prospective clinical study were to characterize ELS behavior in dogs and to examine the extent to which it may be a sign of an underlying gastrointestinal (GI) pathology as opposed to a primarily behavioral concern.”

Researchers looked at 19 dogs, 16 of whom exhibited this behavior daily. This group was compared with a control group of 10 healthy (i.e., non-ELS) dogs. Complete medical and behavioral histories were collected for all dogs. The medical evaluation revealed that 14 of the 19 ELS dogs had GI abnormalities; treatment of the underlying GI disorder resulted in significant improvement in a majority of dogs in the ELS group.

The second study examined seven dogs with a history of daily fly-biting behavior. As the researchers noted, “Fly-biting dogs are generally referred to neurologists or behaviorists because the abnormalities are often interpreted as focal seizures or as obsessive-compulsive disorder (OCD).”

As in the ELS study, these dogs were given complete medical examinations and were filmed to determine if the behavior was perhaps more prevalent after eating. The video analyses revealed a significant finding: all of the dogs demonstrated head-raising and neck extension, which can be an indicator of esophageal discomfort, prior to fly-biting.

All of the dogs in this study were found to have a GI abnormality, and one was also diagnosed with Chiari malformation (a brain/skull disorder). The dogs were treated for their medical conditions, and four had complete resolutions of the fly-biting behavior. The authors of this study concluded, “The data indicate that fly-biting may be caused by an underlying medical disorder, GI disease being the most common.”

As Marty Goldstein, DVM, observed in a post related to this research, “These studies don’t mean that primary obsessive/compulsive behavioral issues don’t exist, because they do … [But] if you have a pet with obsessive/compulsive disorders, don’t jump to psychoactive medications before exploring the use of food-allergy testing, changes in diet, and digestive enzymes and probiotics that can repair a damaged GI tract.”

The Animal Behavior Society Conference
Many presentations featured dogs

Last week, the Animal Behavior Society conference was held in Boulder, Colorado and was attended by hundreds of scientists. Besides being the 50th annual meeting, this conference was notable because of the strong representation by people who study dogs or work with them in other ways.

I first attended an Animal Behavior Society conference in 1994 and I remember no talks or posters about our best friends. Most talks were about insects, fish, and birds, all of which have long been subjects of study in the field of animal behavior. Studying dogs was not respected at that time and many people considered that research on the species was not applicable to science in general because dogs didn’t have a natural habitat other than living with people. I hadn’t started working with dogs professionally yet, and my talk on my graduate research was called “Nest Site Selection by a Member of a Wasp-Wasp Nesting Association.” Oh, how times have changed.

At this conference, dozens of people presented work, whether applied or basic, about dogs, including 21 Certified Applied Animal Behaviorists, or CAABs. (The certification is available to people with PhDs who work in applied animal behavior and have a number of other qualifications. There are currently about 50 of us CAABs.) This conference had more presentations about dogs than any previous ones. There were a number of interesting talks and posters about dogs including:

Differences in social and cognitive behavior between congenitally deaf and hearing dogs

The black dog syndrome: Factors influencing difficulty of canine adoptions

Social bonds between humans and their “best friends”

Improving enrichment for shelter dogs by changing human behavior

Are dogs exhibiting separation related problems more sensitive to social reinforcement?

Do puzzle toys have long-term benefits on canine cognitive functioning?

Inter-dog aggression in the home environment: A behavior modification case study

A comparison of the cognitive development of adolescent dogs

Successful treatment of canine human-directed resource guarding with multiple triggers

I loved attending talks about a variety of species, but seeing how much change there has been in the scientific community’s views about dogs over the last 20 years made this conference extra special.

Disagreement About Dog Domestication
Conflict among scientists who study it

Research about canine genetics and the domestication of dogs is an exciting area of study with many players, so it should surprise nobody that there is disagreement within the field. Multiple groups of researchers from around the world have compared the genomes of dogs and wolves. While they generally agree about the genetic changes that have produced differences between dogs and wolves, their conclusions about the domestication of dogs vary wildly.

The disagreement concerns fundamental aspects of the evolution of dogs such as where, when and why dogs evolved from wolves. So, the location, the timing, and the reason for domestication that various groups propose are not even close.

One group suggests domestication occurred around 10,000 years ago in the Middle East and that it was the development of agriculture around that time that was the catalyst for domestication. Another group claims that it happened around 32,000 years ago in the south of China and related to scavenging alongside the people living there. A third group narrows the time frame for domestication to between 16,000 and 11,000 years ago, and believes that the wolf population from which dogs arose is extinct, making it hard to determine the location of domestication. This third group believes that dogs became domesticated near hunter-gatherers rather than in the presence of an agrarian society.

Much has been made about the discord among scientists studying the domestication of dogs, but it’s hardly surprising. The cutting edge of science is always marked by strongly held opposing views. In the best situations, the intense disagreement among people working in the same field is a crucial part of making progress. Competing hypotheses are critical for the advancement of science. As people challenge each other’s views, all are spurred to study the subject more deeply and design experiments to investigate that which has been called into question. From the ongoing work, the conflicts are eventually resolved as some ideas fall by the wayside and others gain increased support from new data and discoveries.

Sometimes the conflict is cordial and in other cases, it can be very bitter. At this point, the scientists studying dog domestication say that though there is a certain amount of rivalry, they get along and enjoy talking with each other. That may be harder to maintain as people move to the next phase of research into dog domestication and seek to sequence DNA samples from ancient dogs and wolves. The availability of archaeological bone samples is extremely limited so there will be a lot of competition among scientists for both funding to conduct the research and access to the material necessary to do so.

In other words, we can expect a lot of fights over bones in the near future.

Disadvantages of Pet Store Puppies
Unfavorable behavior compared to other puppies

In a study of over 6000 puppies, researchers found that the behavior of puppies purchased from pet stores was less desirable than the behavior of puppies obtained form noncommercial breeders. Specifically, there were 12 areas in which pet store puppies’ behavior was unfavorable compared with puppies from noncommercial breeders and two areas in which their behavior was similar. There were no behavioral areas in which the pet store puppies’ behavior was preferable to the comparison group.

In a recent study called “Differences in behavioral characteristics between dogs obtained as puppies from pet stores and those obtained from noncommerical breeders" used guardian observations of their dogs to compare the behavior between the two study populations. Observations were quantified using the Canine Behavioral Assessment and Research Questionnaire, which uses ordinal scales to rate either the intensity or frequency of the dogs’ behavior

The biggest differences between the two groups of dogs related to aggression with dogs from pet stores being far more likely to be aggressive towards their guardians, to other dogs in the household, to strangers, and to unfamiliar dogs. Among their other unfavorable comparisons with dogs from noncommercial breeders were that they were more likely to have house soiling issues, to be fearful, to have touch sensitivity problems, to be harder to train, and to have issues with excitability.

As a person who has long opposed the selling of puppies in pet stores for humane reasons as well as behavioral, it is with open arms that I welcome this objective study about the undesirability of this practice. It’s heartbreaking for me to think of all the people I have seen professionally over the years who have been emotionally devastated by the serious behavioral issues they have faced with a dog from a pet store. Of course, there are people who have lucked out and obtained a wonderful dog from a pet store, and I am very happy for such dogs and their people. However, it’s important to remember that overall, buying a dog from a pet store does not put the odds in your favor.

The authors of this study sum their research up with this important point: “Obtaining dogs from pet stores versus noncommercial breeders represented a significant risk factor for the development of a wide range of undesirable behavioral characteristics. Until the causes of the unfavorable differences detected in this group of dogs can be specifically identified and remedied, the authors cannot recommend that puppies be obtained from pet stores."

Dogs Attend to Color
It matters more than brightness

One of the most persistent errors about dogs is the claim that they are colorblind. It has been known for decades that dogs can see colors, but research into the details of how they use their color vision can still reveal new information. In a recent study called “Colour cues proved to be more informative for dogs than brightness”, researchers asked the simple question, “Do dogs attend to color or brightness when learning the cues that indicate the presence of food?

In the experiment, researchers trained dogs to make a choice between boxes concealing food. The boxes were each marked with a colored paper, and the dog had to learn which one indicated a piece of meat was inside. Dogs were trained to discriminate between either light yellow and dark blue or between dark yellow and light blue. Then the dogs were tested to see if the cue they used to make correct choices was the color of the paper or the brightness of the paper.

For example, a dog who had learned to choose the box marked by a dark yellow piece of paper was tested with a choice between a box marked by light yellow or a box marked by dark blue. The experimenters were asking whether the dog had learned that “dark” indicates the presence of meat or whether “yellow” does. They found that dogs were making choices based on color, not brightness, in the majority of cases. It was a small sample size of only 8 dogs, but it suggests that dogs not only see color, which has long been known, but that they pay attention to it more than to the depth of color.

It is not surprising that if dogs have the ability to see color that they would use that color functionally in various situations. Asking whether dogs distinguish dark from light when the opportunity to distinguish by color is also present may be an important preliminary step in understanding what dogs attend to. However, I would be even more interested to know whether dogs favor color over shape, color over size or even color over various sounds to make their choices, as all of these seem more biologically relevant to dogs seeking food than brightness does.

Dogs are asked to "Do it"!
And imitate novel human actions and store them in memory

Researchers have shown that dogs can indeed not only mimic human actions, but can retain actions in their memory. According to a new study by Claudia Fugazza and Adám Miklósi, from Eötvös Loránd University in Hungary, this deferred imitation provides the first evidence of dogs' cognitive ability to both encode and recall actions. The research is published in Springer's journal Animal Cognition.

In order to test if dogs possess the cognitive ability of deferred imitation, Fugazza and Miklósi worked with eight pet dogs who had been trained in the “Do as I do method” by their guardians. While dogs are good at relying on human communication cues and learn by watching humans (and other dogs), what this study set out to test was if dogs can perform imitatively not directly after seeing a human do it, but some time after seeing the action.

So they made the dogs wait for short intervals before they were allowed to copy the observed human action. An example of the action done by the human and then performed by the dog was ringing a bell or walking around an object like a bucket.

“The researchers observed whether the dogs were able to imitate human actions after delays ranging from 40 seconds to 10 minutes, during which time the dogs were distracted by being encouraged to take part in other activities. The researchers were looking for evidence of the dogs' ability to encode and recall the demonstrated action after an interval.”

Fugazza described how one of the tests was carried out: “The owner, Valentina, made her dog, Adila, stay and pay attention to her, always in the same starting position. Three randomly chosen objects were set down, each at the same distance from Adila. When Adila was in position, Valentina demonstrated an object-related action, like ringing a bell with her hand.

“Then Valentina and Adila took a break and went behind a screen that was used to hide the objects, so that Adila could not keep her mind on the demonstration by looking at the object. During the break, Valentina and Adila either played with a ball or practiced a different training activity, for example, Valentina asked Adila to lie down. Or they both relaxed on the lawn and Adila was free to do whatever she wanted—sniff around, bark at people passing by, and so on.

“When the break was over, Valentina walked with her dog back to the original starting position and gave the command 'Do it!'. In a control condition, the ‘Do it!’ command was given by someone other than the owner, who did not know what action had previously been demonstrated by the owner. After the 'Do it!' command, Adila typically performed the action that was previously demonstrated.”

It is remarkable that the dogs were able to do this. But the length of time varied—with an action familiar to the dog, delays were as long as ten minutes. If the action/task was novel and the the dogs had not be exposed to it before, they were still able to perform it after a delay of one minute.

“The authors conclude: "The ability to encode and recall an action after a delay implies that the dogs have a mental representation of the human demonstration. In addition, the ability to imitate a novel action after a delay without previous practice suggests the presence of a specific type of long-term memory in dogs. This would be so-called ‘declarative memory,’ which refers to memories which can be consciously recalled, such as facts or knowledge."

To view more demonstration on the "Do as I do" method, see this, and the following demonstrations.

Dog's Life: Humane
Running the Numbers
Guest Editorial
UC Davis studies health conditions in Golden Retrievers

We humans are terrific at measuring and recordkeeping— we even know the length of Noah’s ark, in cubits (300) no less. Technology abets this trait, as computers dutifully crunch our numbers, ad, well, infinitum. As a species, however, we are not so good at appraising information to extract its meaning. Confronted with new data, we tend to overemphasize and generalize, often less than critically.

On that cautionary note, what are we dog people to make of a new University of California, Davis, study that examines relationships between early, late or no spay/neuter and several health conditions in Golden Retrievers? How do we apply its conclusions to the animals in our care?

The Davis docs found increased risk of several cancers, hip dysplasia and cranial cruciate ligament tears among sterilized Goldens; the incidence varied according to the sex and age-at-neuter of their subjects. As such, their findings add to a growing library of veterinary literature on the spay/neuter subject. However, the authors are careful to limit their conclusions, as should we.

First, the findings are breed-specific. Goldens, a highly inbred line, were chosen in part because of their susceptibility to cancers and joint issues. The gene pool was further limited by a study sample of dogs (759, to be precise) seen at the UC Davis clinic, in northern California.

Second, we need to remind ourselves that risk is not destiny, and that correlation is not causation. The study notes that the risk of one type of canine cancer quadrupled in late-neutered females, but also reveals that its incidence grew from 1.6 to 7.4 percent— meaning that about 93 percent of the subjects did not contract the disease.

The authors also indicate that they did not specifically consider obesity, another known factor in dysplasia and cancers. Neutered dogs do tend to be heavier, but we can manage that risk by controlling food intake and quality. We also need to recognize that other studies have noted countervailing positive health effects, as spay/neuter reduces or eliminates rates of other common diseases, such as mammary cancers and uterine infections.

Third, context is crucial. These data feed into the universe of things that are harmful to canines. We know, for example, that nationwide, some 50 percent of the animals in shelters don’t survive the experience. To the extent that intact canines contribute litters to the shelter population, that risk dwarfs exposure to accidents or disease. Shelter “save” rates are improving in many places, but we remain far from a no-kill equilibrium. Job One for canine partisans (including the veterinary community) remains the imperative to reduce that carnage.

After sheltering, risk-of-death varies widely by age and breed. A comprehensive University of Georgia study of vet-reported deaths (“Mortality in North American Dogs from 1984 to 2004,” published in 2011) identifies infections, trauma and birth defects as primary culprits in young dogs, with tumor-related diseases at various breed-specific rates, distantly followed by trauma and infections, which dominate the tally for the late-in-lifespan.

Finally, there are the behavioral and other risk implications of fertility, including management of ardent males and bitches in heat.

The Davis study is a significant contribution to our understanding of the unintended consequences of fertility management in a useful and popular breed. Reproductive organs contribute hormones for many reasons—it would be surprising if their removal were completely trivial. Alternatives to traditional spay/neuter do exist, but they are rarely performed. Injectable sterilizers and contraceptives are coming on the market (they, of course, will carry their own measurable side effects).

It’s important to recognize the limitations of the study: one breed, one gene pool, defined conditions and their rank among all the calamities that can befall our best friends. The study itself notes that spay/neuter is uncommon in Europe, which would appear to open up a range of comparative research possibilities and fertility management options.

We should add the Davis work to the burgeoning database. But until a lot more measurements have been taken from which broader conclusions may be drawn, the best advice is not general to all dogs, but individualized: choose your canine companions carefully and love and support them well, and completely. And recognize that we can’t measure or control for everything, yet—or ever.

Tough Choices About End of Life
Deciding when to euthanize

Not everybody is at ease with the idea of euthanasia under any circumstances, and I understand that. Many people have moral conflicts with deciding to end the life of a pet, no matter what the reason. My perspective is that this is a highly individual decision but that I personally am comfortable with euthanizing my pets once their quality of life is so compromised or they are in such pain that keeping them alive feels like it’s more for my sake than for theirs. It’s my view that a peaceful death by euthanasia frees them from pain and misery, and is the final gift of love I am able to provide. I know many disagree, and I’m not suggesting that one way or another is right—I’m just describing my own personal take on this issue.

That doesn’t mean that I haven’t cried buckets and been inconsolable when I’ve euthanized a dog. It’s horrible beyond imagination, and I’ve never really recovered from it in any case. I always hope for any dog (or any person for that matter) to surrender peacefully to death while sleeping. When that doesn’t happen in time, facing the tough decision of when to euthanize is a challenge. Sometimes it’s obvious when it’s time because the dog has reached a point of literally being unable to move, being in constant and unmanageable pain, showing no joy at all or no recognition of anything or anyone.

In other cases, it’s not so clear, which is why a new tool that helps guardians and veterinarians decide when that moment has arrived may be useful. Researchers at Michigan State University developed a survey for probing into the specifics of a dog’s quality of life when undergoing chemotherapy for cancer. The idea is to develop an objective way to assess quality of life, which is such an important consideration when deciding whether to continue life-prolonging measures or to face the possibility that it is time to say good-bye.

Questions address a range of behavioral issues and observations before treatment, a retrospective on the dog’s behavior six months prior, and continued observations throughout their treatment at regular intervals. The questions address aspects of dog behavior including play, measures of happiness, and signs of disease. Both guardians and veterinarians have questions to answer based on their own observations. A small pilot study of 29 dogs found high levels of agreement from clinicians and guardians. Researchers plan to expand their original work to a study with hundreds of dogs and to other illnesses and medical issues as well.

Do you think an objective tool such as this might help you decide when to euthanize a dog, or do you feel comfortable with just “knowing” when that sad day has come?

Dogs Are Like Children To Us
Science supports what we’ve long believed

Our dogs are our kids. It’s not rocket science—we love them, they love us. They look to us for comfort and care. We call them our fur kids or our four-legged children. So, even though it’s not news to us, it’s validating to see science confirm what we already thought was true: Our dogs are like children to us.

Children have been shown to explore the world most confidently if they have a strong attachment to their caregiver (usually a parent.) They use the parent as a secure base from which to explore their environment if they have learned that the parent is dependable and reliable, and this phenomenon is called the secure base effect.

In the recent study, The Importance of the Secure Base Effect for Domestic Dogs—Evidence from a Manipulative Problem-Solving Task, researchers conclude that dogs are bonded to their guardians in the same way that infants are bonded to their parents. They found that dogs use their guardians as a secure base, just as children do.

In the study, dogs were tested in each of two experiments and their behavior was quantified. In the first experiment, dogs were given the opportunity to obtain food from interactive dog toys, and the amount of time the dogs spent attempting to extract the food was recorded. The dogs were tested in three different experimental situations: 1) with their guardian absent, 2) with their guardian present and encouraging them, and 3) with their guardian present but silent and unresponsive. Researchers also recorded how much time the dogs spent in close proximity to their guardians as well as to the experimenter, who was present in all conditions.

The results of this experiment showed that the different situations had an impact on how long the dog manipulated the interactive toy in an attempt to extract the food. The dog manipulated it longer when the guardian was present than absent, but there was no difference in response to whether the guardian was encouraging the dog or remaining silent. The dogs spent an equal amount of time close to their guardian regardless of whether they were receiving encouragement or not. They spent more time close to the experimenter when their guardians were absent than when they were present, suggesting that the experimenter offered some security, social support or comfort in the experimental context.

The second experiment was designed to determine if the effects seen in the first experiment could be explained simply by the fact that in the situations in which the guardians were present, there were two people in the room, whereas in the guardian-absent condition, there was only one person. In other words, what if dogs are not affected by having their guardian as a secure base, but simply react to the presence of more than one person in the room? So, in experiment two, the first experiment was modified to include a fourth condition in which an unfamiliar person (rather than the guardian) was present along with the experimenter.

The results of the second experiment were that dogs manipulated the interactive toy longer in the presence than in the absence of their guardians, regardless of whether an additional unfamiliar person was in the room. The dogs spent more time near their silent, unresponsive guardians than to the unfamiliar person, who also refrained from interacting with the dog. The addition of the unfamiliar person condition allowed the researchers to determine that the guardian had a specific effect on the dog’s performance that cannot be explained by the presence of just any person.

Prior to participating in this experiment, all dogs were tested for their willingness to eat food in the absence of their guardians. They were also scored for their tendency to exhibit separation distress when kept away from their guardians. Interestingly, there was no relationship between the time spent manipulating the toys in the absence of their guardians and the amount of separation distress they showed, which means that the results of the experiments cannot be explained by a tendency of the dogs to manipulate the toy less because of the distress of separation.

This is the first study to demonstrate that the relationship between dogs and guardians is similar to the relationship between children and their parents in that both involve the secure base effect. This raises concerns about experiments into cognitive abilities that involve problem solving that is far more complex than in this study because the absence of guardians could significantly lower performance by the dogs.

It also confirms the view that most of us have about the canine members of our family—they are like kids to us!

Dog’s Personalitites
Studies now suggest that personality in non-human animals can be measured and evaluated, just as in humans.

All dogs are the same. really. Look at an evolutionary tree and you’ll find all domestic dogs, clustered together in one spot. But that can’t be the entire story. When asked, Rachel Licker of Lawrenceville, N.J., describes Piper, her “Basset Hound on stilts,” as incredibly goofy, communicative, playful and quick to overwhelm. According to Mary de Vachon of Nice, France, Ria, her Sheltie, is gentle and loving, content and confident, extremely shy, and above all else, a mademoiselle.

While all dogs might fit in the same spot on the tree of life, each has his or her own unique personality. Just as one person might greet you with a cautious wave or a coy smile, another will come barreling into your life doling out hugs and kisses. Dogs are the same, in that each is different.

WHAT IS PERSONALITY?
While the name Pavlov usually brings to mind bells and salivating dogs, early in his studies Pavlov and his students noticed that dogs differed from one another. Some tended to be nervous and sensitive, some were active and lively, and some were quiet and steady. Like Rachel and Mary reflecting on Piper and Ria, Pavlov and his team were describing dogs’ personalities. The concept of personality can be used to convey that individuals differ in how they perceive and interact with the world around them.

Additionally, the word describes an individual’s usual pattern of behavior, characteristics that are relatively stable over time and across situations. Say a snowman with stick arms that wave in the wind appears on the front lawn after a snowstorm. Some dogs would walk by as though Frosty had always been there. Others might play-bow and dance joyfully in front of their new friend, while a few are sure to freeze, tuck and retreat.

If those same dogs then confront other novel situations—balloons in a tree, a parade, clowns jumping out of a car, you name it—those who perceived Frosty as no bother would probably continue to be indifferent, while those who equated Frosty with Satan would also be likely to associate other odd events with the underworld. Although it does not imply that an individual will respond the same exact way every time (dogs are not robots, after all), the term “personality” denotes an individual’s usual perceptions or interactions.

Thinking about personality gets tricky very quickly because there is no universal definition. Some fields distinguish between personality and temperament, while others use the terms interchangeably. As Samuel Gosling, PhD, a personality and social psychologist at the University of Texas, Austin, explains, “Temperament is the basic, biologically inherited tendencies of an individual, and personality is the result of the interaction between temperament and the environment.” That distinction is common in human psychology but is not always made in animal fields. But, as Gosling adds, “since adult animals are a combination of biologically inherited tendencies as well as individual experiences, it seems to me misleading to call that temperament. In humans, we would call that personality, so why not in other animals?”

Making a distinction between temperament and personality could enable researchers to explore whether certain traits are more stable over time than others. For example, a recent analysis surveying a number of studies found that in puppies, aggression and submissiveness were most consistent, while responsiveness to training, sociability and fearfulness were least consistent.

Understanding the relationship between early-life temperaments and later-in-life personalities could be paramount for real-world issues, such as selecting dogs for work or companionship. For working dogs, Gosling and his team advise the U.S. Department of Homeland Security on how to measure personality-trait consistency in order to improve the selection and training of working detector dogs.

Back home, you might think you have a handle on who your puppy Wizzer is, but what you’re seeing might or might not relate to Wizzer’s adult personality. (So even if Wizzer starts out apprehensive about the vacuum cleaner, there’s hope for improvement, and you can help him.)

At the same time, many shy away from using the term when it comes to non-human animals, sometimes because they’re uneasy about the “A” word: anthropomorphism. To avoid linking dogs and personhood so explicitly, scientists use alternative descriptors such as “behavioral types,” “behavioral syndromes” and “coping styles.” Regardless of the word employed, when the definitions are compared, they tend to describe the same basic phenomenon: consistent, individual differences in behavioral tendencies over time and across situations.

Much of the initial pushback against the term “personality” has dissipated because studies now suggest that personality in non-human animals can be measured and evaluated, just as in humans. (Relatively speaking, this field is in its infancy, and techniques and methodologies continue to evolve, so stay tuned.)

HOW IS PERSONALITY EVALUATED?
While human personality is often assessed by questionnaires, dogs are less adept with that format, tending to provide insufficient responses (mostly, slobber and paw prints). But their inability to hold a pen does not exclude them from questionnaire-based personality assessments; humans complete questionnaires on dogs’ behalf. The method is reliable because independent observers—in this case, dog owners and other humans who know the dog— generally concur in their descriptions of a dog’s personality. This type of consistency is a hallmark of human personality research and lends credibility to the approach. And, even better, similar ratings provided by observers over time further substantiate the utility of particular questionnaires.

Questionnaires, however, are not bulletproof. Gosling notes that questionnaires “don’t rule out the possibility that ratings are based on some stereotype, say a physical stereotype, like ‘bigger animals are more aggressive.’ You could still get those biases.” Dogs’ physical appearances are emotion points for humans and make them susceptible to attributions and judgments that might have no bearing on the personality of individuals. For example, the Papillon breed standard specifies that these small dogs are to be “happy, alert and friendly,” and their physical appearance easily promotes this perception of an overall perkiness. But on an individual basis, just like other dogs, Papillons can be shy (or downright neurotic).

Even taking into account the risk of stereotyping, questionnaires provide meaningful information about canine personality. When comparing questionnaire ratings with separate behaviorobservation assessments, a strong link has been found. So if a dog is judged on a questionnaire to be highly timid, independent observers will generally also describe the dog’s behavior in terms consistent with shyness.

Since people are rarely shy about discussing their dogs, collecting data via questionnaires can be incredibly fruitful. The Canine Behavioral Assessment and Research Questionnaire (C-BARQ), developed by James Serpell, PhD, and researchers at the University of Pennsylvania, is a widely used assessment of dog behavioral characteristics (available for public use). The 101 questions gather insights into dogs by asking owners to use a five-point scale to describe how their dog would likely react in a variety of different situations, such as anxiety or fear in heavy traffic or when examined by a veterinarian; excited when the doorbell rings or when visitors arrive; and of course, likely to chase cats if given the opportunity.

A recent study of former breeding dogs from commercial breeding operations— commonly referred to as “puppy mills”—relied on the C-BARQ to evaluate the dispositions of these dogs once they’re out in the world. Overall, they were found to be more fearful and nervous than typical pet dogs, particularly regarding strangers and stairs, and many were sensitive about being touched. Despite having lived for years in their adoptive households, many of these dogs still displayed persistent fear and anxiety, which is exactly the type of long-term rather than short-term tendencies that investigations of personality aim to reveal.

But do we really need questionnaires when a dog’s actual behavior is right in front of us? Of course, it’s easy to watch a dog and write down how he or she reacts to various stimuli, but that’s not necessarily enough. While it is plausible to observe dog behavior in myriad situations by simply waiting for different scenarios—such as flashing lights and loud sirens—to present themselves, test batteries, which are designed to investigate whether various stimuli and situations elicit particular responses, are more common. For example, the Dog Mentality Assessment (DMA) is a behavior test originating in Sweden that requires dogs to respond to, among other things, novel people, furry objects, loud noises, the potential for play and people dressed up like ghosts (yep, ghosts).

The researchers boiled down dogs’ behavioral responses into five personality dimensions: sociability, playfulness, chase-proneness, aggressiveness, and curiosity/fearfulness. Comparing the results from the DMA test battery with the C-BARQ assessment showed broad agreement between the two.

You can think of these personality dimensions as the canine equivalent of the classic human “Big Five” personality models: extroversion (sociable and outgoing), agreeableness (trustworthy and straightforward), neuroticism (anxious, irritable and shy), openness (curious, imaginative and excitable) and conscientiousness (efficient, thorough and not lazy). Research groups continue to flesh out the various personality dimensions found in dogs; recently, the Anthrozoology Research Group in Australia generated a slightly different list of attributes, one that included extroversion, neuroticism, motivation, training focus and amicability.

As you might imagine, it’s not easy to summarize and sort all of a dog’s behaviors into a small number of buckets, so there is much left to learn in this area. One hot topic that warrants more research is the possible relationships between different traits. For example, are individuals who are more bold also more sociable and playful with strangers? Or is it more challenging to find links between traits? While boldness and aggression correlate in some species, researchers have not found that to be true for dogs. Dogs who were bolder were not necessarily more aggressive. The possibilities for this area of research are virtually endless.

WHO WILL MY DOG BE?
At any given moment, chances are that a Beagle’s nose will be pressed to the ground while an Afghan Hound will be striking a pose on the couch. But personality encompasses both genetically selected attributes as well as individual life experiences. For that reason, there is no oneto- one relationship between personality characteristics and breed; personalities can vary within a particular breed based on the experiences of individual dogs. In fact, in the recent book, Dog Sense: How the New Science of Dog Behavior Can Make You a Better Friend to Your Pet, anthrozoologist John Bradshaw comments that even in Scott and Fuller’s seminal research on dog behavior and genetics, “breed turned out to be less relevant to personality than had been expected at the outset.” The bottom line is that breed characteristics are certainly relevant to who a dog is, but they are not the be-all and end-all when it comes to personality.

The short answer to “Who will my dog be?” is “Wait and see.” Current research finds that puppy tests have low predictive value for later-in-life behavior. On the other hand, personalities examined in older dogs do display more stability over time. Krista Macpherson, a PhD candidate at the University of Western Ontario who studies cognitive abilities in domestic dogs, reminds us that at the time of testing, puppies have had minimal interaction with the outside world, apart from their conspecifics. “At eight weeks, they are not that developed cognitively, and there are a lot of experiences yet to be had,” she observes. Researchers at the Clever Dog Lab (part of Austria’s University of Vienna) are currently investigating whether early temperament tests are predictive of behavioral tendencies in an older dog. By testing dogs at a range of ages, they will be able to explore the predictive value of early-life temperament tests.

At the end of the day, Jules Winnfield, the gangster from Pulp Fiction, gets it right: “A dog’s got personality, and personality goes a long way.” Rachel Licker, who lives with Piper, reminds us exactly why personality is so important. “I hope people really enjoy their dogs being more than just amicable, and give their dogs more leeway to be multi-dimensional beings. I think they might enjoy their dogs more, and I think it would create more space for the dog and owner to be happy together.”
