Good Dog: Behavior & Training
How does your dog react to people, cats and dogs?
February 18 2017
Recently, I had a client whose resource-guarding dog reacted very differently depending on who in the household approached him when he had a toy. His responses varied with the species of the individual.
The other dogs in the house are watched closely if they come near the dog in question when he has a toy. He will go still except for his eyes, which track their every move. If they try to pick up one of his toys, he will growl and charge at them. He will take toys from them and hoard them even if they all started out with matching toys given to them by the guardians. If you only saw him around other dogs, he presents as a classic high-level resource guarder—what’s mine is mine, what’s yours is mine. However, he reacts very differently to the other two species sharing his home.
The human adults and the child in the household can do whatever they want with this dog’s toys. They can pick them up, remove them from the dog’s mouth, walk by them or even step on them. The dog is completely relaxed no matter what happens to his toys at the hands (or the feet) of the people in his family.
The cat can walk by toys, approach the dog while he is playing with a toy or even cuddle up with him when he has one without eliciting any reaction. If she picks up a toy up or lies down on top of one, the dog rushes over and takes it.
This dog lets people do anything related to toys, and lets the other dogs in his house do nothing related to them, but takes an intermediate stance with the cat. He is unwilling to tolerate the cat taking possession a toy, but as long as she does not attempt to do that, he does not object. It’s difficult to know exactly why this dog behaves as he does, though I think it’s safe to assume that he does not regard the dog as a human/dog cross. It’s possible that the dog’s actions are based on species, but the differences may simply reflect his response to each of the individuals in his multi-species household.
Do you have a dog who reacts differently to the various species in your home when they approach his toys?

They show a bias against them
February 16 2017
In a study called “Third-party social evaluations of humans by monkeys and dogs” scientists evaluated capuchin monkeys and domestic dogs to investigate their responses to people after watching them interact with other people. Specifically, researchers studied their evaluations of people who were either helpful or who refused to help another person. There’s an entire behavioral area of research involving what are called “third-party social evaluations” which simply means the study of how individuals respond to people after watching them interact with others.
In the experiment with dogs, the person pretending (for the sake of science) to be in need of help was the dog’s guardian. The dog watched as the guardian spent about 10 seconds attempting to open a clear container holding a roll of tape. In the “helper” situation, the guardian then turned to one of the people on either side of him/her and held out the container. The helper held the container so that the guardian could open it. The guardian removed the roll of tape, showed it the dog, put in back in and replaced the lid. In the “non-helper” condition, the person who the guardian turned to for help responded to the non-verbal request for assistance by turning away, at which point the guardian continued with the unsuccessful attempts to open it. In both cases, there was a person on the guardian’s other side, who was not asked for help.
At the end of this role-playing situation, both the person who was asked for help and the other person next to the guardian offered the dog treats. When the person had helped the guardian open the container, dogs were equally likely to take the treat from either person. However, when there was a refusal to help, dogs were more likely to choose the treat held by the person who was not asked for help. Dogs chose to avoid taking treats from people who were not helpful. This study found similar results in capuchin monkeys, and the same pattern is well known to occur in children.
It is interesting that dogs act as though they assume that people are okay and trust them—until they have evidence to the contrary. In this study, they gave people the benefit of the doubt, reacting just as well to people who were never asked for help as to those who did provide help. Once they observed someone refuse to help their guardian, though, they avoided taking treats from them. This matches the experience many of us have with dogs in that behaviorally healthy, well-socialized dogs seem to like and trust people in general. It as though dogs pursue a “trust unless specific information advises me to do otherwise” strategy regarding social interactions.

Behavioral changes may be falsely attributed to age
February 11 2017
It’s natural for an older dog to rest more, to play less and to be without the pep so prevalent in earlier years. The aging process changes us all, but that doesn’t mean that every change in an elderly dog is due to aging. Sometimes a dog is feeling unwell, and we make sense of his actions by attributing it to his age. This is especially true when the decline is gradual.
We often don’t realize that the behavior we’ve been seeing is a result of a medical issue until it is resolved. That’s when people say things like, “He hasn’t been this energetic in three years!” or “It’s been so long since I’ve seen him play with our other dog. I thought he just didn’t like to play anymore.”
Recently, I had a friend share with me that her 12-year old dog was diagnosed with cancer. The dog has recovered well from the surgery to remove the tumor, and is currently undergoing additional treatment. The change in him in the six weeks since learning he was ill has been remarkable. He is eager to run at any pace and to go on long hikes, which is in contrast to the indifference he exhibited towards these activities in the last couple of years. He is playing with the other dog in the house, a seven-year old female, which he has barely done for two years. My friend is thrilled to see him doing so well, and appearing so energetic and happy. She is also heartbroken with the realization that his “old man ways” were because he was sick, not because he was getting old. She wishes that she had known to get him into treatment earlier, but nobody could blame her. He went to the vet regularly and had no obvious signs of the illness until recently. The decline in energy as well as losing interest in play happened so gradually, and at the age when it affects most dogs.
I’ve heard many similar stories over the years, because it’s so easy to attribute a general decline in energy and playfulness to getting older, when that may be only one piece (or no part!) of the explanation for the changes. Have you had the experience of realizing that your old dog’s behavior wasn’t just due to the passing years?

Humans’ empathy, personality and experience play a role
February 8 2017
People understand and react to the facial expressions of dogs in ways that are similar to their responses to people’s expressions. Dogs can distinguish positive human expressions from negative ones, showing that they perceive the emotional content of human expressions. Our mutual understanding of one another is astounding considering that we’re not all that closely related, and yet few humans are surprised by it. We feel a kinship with our canine companions that goes beyond what we share with members of any other species except our own. The biological miracle of our relationship with dogs deserves the attention of scientists, and happily, that is happening more now than ever.
One recent study investigated the role of empathy, personality and experience on people’s ratings of facial expressions. People were asked to rate the expressions (in pictures) of people and dogs showing neutral, threatening or pleasant expressions with regard to each of the basic emotions of happiness, sadness, anger/aggressiveness, surprise, disgust or fear. They also rated how negative or positive the expression was. The study, “Human Empathy, Personality and Experience Affect the Emotion Ratings of Dog and Human Facial Expressions” found that many factors affect how people perceive the expressions of others.
People’s experience plays a smaller role in interpreting facial expressions of dogs than their personality and ability to be empathetic. This suggests that people have a natural, inherent ability to understand the facial expressions of dogs. Perhaps this is because we have co-evolved with dogs over thousands of years, but it may also simply be a result of the similarity of many facial expressions between humans and dogs. We share many of the same muscles and movements as dogs, as do many other mammals, an idea that was made popular in Charles Darwin’s classic work “The Expression of the Emotions in Man and Animals” which was published in 1872. In that book, Darwin made the case that similar behavior in humans and other animals indicated similar internal emotional states, including emotions such as anger, fear, surprise, happiness, disappointment and love. He presented photographic evidence that humans and other animals reveal their emotions through similar facial expressions and behaviors.
Though the role of experience is minimal, it still has an effect on people’s interpretations of canine facial expression. People who were involved in dog-related hobbies such as agility, obedience or hunting, rated happy faces of dogs as “more happy” than people who lack such experience. Experienced people were also more likely to rate neutral expressions as happy, perhaps indicating the subtly of relaxed, content expressions in dogs, or a more positive views of dogs among people who have a lot of experience with them.
Empathy—the ability to understand the emotions and experiences of others—played an especially strong role in the way that people perceived canine expressions. People who are particularly empathetic interpreted the facial expression of dogs more intensely and more quickly than people who are less empathetic. Researchers point out that it is not known whether empathetic people are any more accurate in their assessments of canine expressions.
Personality traits such as being extroverted or being neurotic influenced people’s interpretation of facial expressions. Extroversion influenced ratings of human expressions, but not canine expressions. Neuroticism scores were correlated with lower rankings of anger/aggression in neutral expressions of both species.
The results of this study show that there are many facets to interpreting the emotional expressions of both dogs and humans, and that psychological factors in the observer have an influence. Reading dogs’ facial expressions is a talent and a skill—both natural ability and experience influence people’s reactions to them.

More satisfaction, less conflict characterize relationship
February 4 2017
Long before people began to consider dogs members of the family, many kids were wishing that instead of brothers and sisters, they could just have more dogs. Dogs (and other pets) fulfill all of the roles that researchers consider important in an attachment figure. Kids find them enjoyable, comforting, they miss them when they are not around and they seek them out when they are upset. That may make them especially important for adolescents, who are learning to rely less on their parents and more on relationships with other individuals. The non-judgmental feeling people experience with their dogs may contribute to enhancing young people’s self-esteem.
We know that pets are important to kids, but scientific studies quantifying the value of their relationships are sparse. The recent study “One of the family? Measuring young adolescents' relationships with pets and siblings” demonstrates the true value that kids place on their pets. The research involved surveys of 77 people who were 12 years old. It made some interesting, if hardly surprising conclusions:
If many adults consider their relationships with dogs to be like those they share with children, it’s no wonder that many kids relate to their dogs much like they relate to their brothers and sisters—only better!

Familiar dogs prompt generosity more than unknown dogs
February 1 2017
Dogs will give food to other dogs. Okay, maybe your dogs don’t show this tendency at home enough for you to believe it, but in laboratory settings, it happens. (It happens in other species, too, especially in various primates and in rats.) A recent study of this behavior found that the details of the experimental situation influence whether dogs choose to give food to other dogs or not.
“Task Differences and Prosociality; Investigating Pet Dogs’ Prosocial Preferences in a Token Choice Paradigm” investigated prosocial behavior—voluntary behavior that benefits others. In the study, dogs were trained to touch a token with their nose to deliver food to another dog who was in an enclosure, or touch another token that resulted in nothing happening. This is a different experimental design than has previously been used in which a dog could pull a shelf with food on it so that the food reached a dog in another enclosure, or pull an empty shelf.
In the experiment with the tokens, sometimes the dog in the enclosure was one that the “giving” dog lives with, sometimes it was an unfamiliar dog and sometimes the enclosure was empty. In some trials, there was a dog next to them when they were choosing whether to touch the token to give food away. Sometimes they were alone when making their choice.
The study found that 1) Dogs were more likely to give food to dogs who they live with than to dogs who are strangers. 2) Having another dog with them made them more generous, meaning that they were more likely to give food when they were with another dog rather than when they were alone.
To be fair, the dogs were not literally sharing the food out of their own bowl. They were choosing to act so that food would be given to another dog, but they didn’t lose out on any food by giving to the other dog. Still, it’s nice to know that dogs can share food, even if what we most appreciate about them is their ability to share love!

A different perspective than most canine research
January 28 2017
A recent research paper “(Just) a walk with the dog? Animal geographies and negotiating walking spaces” is based on the premise that the walk is an interesting event for studying the human-canine bond. The general conclusions of the study were that the personalities of both human and dog influence the walk, and that the walk is a part of life which involved power negotiations between the dog and the human. It also reports that according those interviewed for the study, people want their dogs to enjoy getting to “be a dog” by running free on walks.
This research is so different than most other research on dogs and dog behavior, and at least part of the reason is that the background of the researchers is completely different. They are not ethologists, animal behaviorists or psychologists, which are the scientists that publish the majority of studies on canine behavior. The lead author of the paper, Thomas Fletcher, is a specialist in the sociology of sports and leisure with special interest in race, ethnicity, diversity, social identities and heritage. The second author on the paper, Louise Platt specializes in festival and event management with an interest in cultural identity and constraints of social norms.
The research and its conclusions seem pretty simple for anyone familiar with dogs and what we have learned about them and our relationship with them over the past few decades. What interests me about the study is that it reveals a perspective on dogs that will be unfamiliar to many in the dog world. The article indicates that the researchers hold an antiquated view of the relationship between dogs and humans, stating that “the walk reflects the historical social order of human domination and animal submission,” going on to point out that the walk “allows humans and dogs to negotiate their power within the relationship” and that “Rather than there being a one-way flow of power where the human is dominant, the dog walk is where humans and dogs negotiate power within their relationship.”
The study consisted of 10 interviews with dog guardians about their dog walking experiences. From these meager data, the researchers made their conclusions, most of which are already known. (For example, “The data reveal that humans walk their dogs in large part because they feel a deep-rooted emotional bond with them and hold a strong sense of obligation to ensure they stay fit and healthy. Perhaps more interestingly, humans also walk their dogs because they believe their dogs have fun and are able to be more ‘dog-like’ while out on a walk” and “The walk was seen as an invaluable opportunity for dogs ‘to be dogs’. There was widespread belief that dogs are happiest when out in the open, and it is here that they are able to best demonstrate their ‘dog-ness’.”)
My initial response to this study was negative because of the small sample size, the rather obvious conclusions and the out-of-date perspective on the relationship between our two species. But my second impulse was to value the fact that the researchers were investigating dog and human interactions from a field that has largely ignored animals and their role in human lives until all too recently. They clearly plan to do more research, based on their statement that “Moving forward, we would like to see research taking place that can capture the ‘beastly’ nature of animals, allowing them to act without human interference.” Becoming more familiar with previous research about dogs and understanding our strong evolutionary history will hopefully guide their future research, allowing them to make worthwhile contributions in the future.
Though I was not impressed by the research or its conclusions, some of the quotes from the transcripts of the interviews are quite relatable, and will likely resonate with many dog lovers. I especially loved this comment: “One of the biggest joys for us is when one of us stands at one part of the field and the other; and he just runs. And we’ve managed to time him. He does 30 miles an hour. And he looks like a cheetah, he looks like a wild animal. And it just makes your heart, I mean, I feel a physical change in my body when I watch him run, which has never been created by anything else, really.”

Dog makes the most of opportunity
January 25 2017
Coming when called and ignoring anything interesting along the way is a challenge for dogs. Two dogs in this video succeed, running right to their guardians even though there are so many exciting distractions. The third dog? Well, he has a glorious time even if he doesn’t do what his guardian wanted.
It’s fair to say that he needs more training to fully master the task. Dogs who succeed with this much temptation have likely had extensive training in similar situations, although the occasional dog is so gifted at recalls that this task is not as challenging as for the rest of the dogs on the planet. For the sweet dog in this video who is clearly not one of those “gifted at recalls” dogs, the incident in the video is a huge training setback. Potentially, it was an opportunity to learn that ignoring all the goodies and going directly to his guardian is the way to “win” because he gets to play or receive something of great value. Instead, he learned that there is a lot of great stuff to be had along the route and that being a “stop and smell the roses” kind of guy is a great strategy for getting the most out of life.
I find it endearing that nobody becomes upset with the dog. His guardian simply goes closer to him with a toy to influence his behavior so that he does (eventually) come to her. Everyone remains cheerful despite the dog’s epic failure, and nobody is more delighted than the dog.
Dog's Life: Humane
Training of dogs for movie under scrutiny
January 19 2017
The movie “A Dog’s Purpose” is suffering what can only be called a PR disaster after footage has surfaced showing unacceptable treatment of one of the dogs during filming. In response to the treatment of the dog, many people have vowed to boycott the film, which will be released next week.
In the clip that is causing the controversy, a German Shepherd is being forced into turbulent water to film a scene in which the dog rescues a child from drowning. The dog is being physically pushed into the water despite clearly resisting, and even climbing back out using the side of the pool and the trainer as footholds. The dog looks panicked, and is making obvious efforts to avoid being tossed in the water, even clawing at the edge. You can hear someone say, “Don’t worry, it’s warm water at least,” and “He ain’t gonna calm down till he goes in the water” and “You just gotta throw him in,” all of which show complete disregard to the well-being of the dog, who is truly terrified. At one point, you hear someone say, “I think he wants to go in,” which is clearly wishful thinking. The next thing you hear is the more truthful, “He wants to get away! Just throw him in,” which is exactly what happens, to the chagrin of most viewers. Once he is in, he goes under, and it turns frantic on set. You can hear someone yelling, “Cut it, cut it!” and people are running towards the submerged dog.
The one bright spot in this clip is the boy in the water, who about halfway through is calling out cheerily, “Here boy, here boy” at which point the dog looks calmer and more relaxed than at any other point in the 60 seconds of footage. Additionally, it is this child who rushed first and fastest to the dog when he is submerged. I don’t see evidence that the filmmakers are concerned enough about the safety and feelings of the dog, but the child actor is, and I give him credit for that.
The American Humane Association (AHA) is responsible for the No Animals Were Harmed program, which is supposed to insure the well-being of animal actors on set. However, they have a history of ignoring poor treatment of animals during moviemaking. In response to this recent controversy, the AHA has suspended the safety representative who was on set that day and say they will investigate the incident.
The behavior of entering turbulent water in the chaotic situation associated with making a film needed to be approached step-by-step so that the dog was trained to do this ahead of filming. It would take a lot of work and a considerable amount of time to help almost any dog feel comfortable in this situation, and based on this clip, that investment was not made, and it is the dog who suffered. Another option if a dog is unable to handle the scene without distress would be to use a stunt double—a dog who is more comfortable with water.
What’s your take on the treatment of the dog during the filming of this scene?

So, obviously the dog is included!
January 18 2017
We all know that there’s a special place in our hearts for our dogs, but it turns out that there’s a special place in our brains for them, too. It’s right in the same spot where our minds keep track of everyone else in the family, according to a study about accidentally calling someone by the wrong name. When a parent says, “Sadie! Max! Zoe! I mean, Jack!” sometimes, the dog’s name shows up in the string of names as we search our files, so to speak, to find the right name. (Apparently, this kind of name soup is epic among parents—no surprise there.)
In the paper, “All my children: The roles of semantic category and phonetic similarity in the misnaming of familiar individuals” in the journal Memory & Cognition, cognitive scientists found that this analogy of “searching your files” is a good way to think about the scrambled name phenomenon. Mixing up friends’ or family members’ names is a very common “cognitive glitch” as people in the field say. It is not caused by a bad memory or by aging processes that affect brain functioning. It’s simply a result of the way our brains categorize those we love.
When your brain is attempting to retrieve a name so that you can say it, it’s likely that another name in the same group will come to your lips instead of the one you meant to say. That’s because in order to find the name you’re looking for, you are essentially opening and flipping through the whole set of names in that group, which includes all beloved family members. That explains why so many of us have not only been called by our brother’s name or by our sister’s name, but by the dog’s name as well. Our brains, just like our hearts, file our dogs as loved and cherished family members.
The scientists who conducted this study reported that we are far more likely to throw the dog’s name into the mix than the cat’s name, or the hamster’s name, or any other animal’s name. It also showed that the category in which the person belongs (family, close friends, etc.) was far more influential in causing a mix-up than any phonetic similarity between names.
Isn’t it great to know that when you call others by the wrong name, it’s evidence of your love for them all?
