Is your dog bothered by foul water?
April 26 2016
Dogs are famous for drinking out of the toilet. Though that does make me wrinkle my nose, it is far from the most disgusting water that I have seen dogs drink. I’m not talking about dogs who are lost in the desert taking in fluid from any source to stay alive. Even from my human perspective, that seems like an extremely rational choice.
I’m talking about healthy, well-cared for pets who think that a nearly dried up scum-covered pond that is more muck than water looks extremely appetizing. I’m thinking of dogs who pass up a freshly filled, clean water bowl to lick the muddy spots that melted off my snow boots and onto the kitchen floor. And I’m calling to mind those individuals who are drawn to the water that has run through the pot containing a houseplant and into the saucer below. Yes, I’m referring to the one that is coated with algae and has probably never been cleaned.
Amazingly, dogs tend to drink from the most unlikely sources without incident the vast majority of the time. Some weird water choices are usually harmless. If your dog licks the water off your legs after a shower, it’s unlikely to be a problem, especially if you rinsed well. However, their interest in fluids that we don’t want them to drink can be disastrous. There’s the obvious risk of exposure to serious water-borne diseases such as leptospirosis and giardia. Even more alarming is the risk to dogs who are attracted to antifreeze or windshield de-icing fluid because the ethylene glycol they contain can cause kidney failure and even death.
By comparison, the toilet seems like a reasonable place for the average canine to quench his thirst!
Does your dog have a favorite watering hole other than his bowl?

Even more surprising, it’s a Great Dane
April 22 2016
We all know that rescue people are called in to save cats from trees. It’s not even that unusual for kids to need help getting back down to earth from time to time. However, when firefighters were called to help a Great Dane who was stuck in a tree, they thought it was a prank—until they arrived and saw Kora, all 120 pounds of her perched 20 feet high in a huge tree.
Her guardians don’t know how Kora managed to get up so high in that tree. They do know that she loves to wander and that she chases small animals, so their best guess is that some little critter enticed her to jump a five-foot fence and climb so high in the tree that she couldn’t get down.
To rescue her, the first plan was to encourage her to come down the way that she had come up, but Kora vetoed that idea. Plan B involved putting her in a harness and lowering her to the ground. That proved partially effective, until the harness broke as she neared the ground. The rescuers were prepared for that possibility, though, and when she fell, she landed safely in the net being held under her.
To many people, the most fascinating part of this story is that such a large, lanky dog was able to climb a tree and get herself in this mess in the first place. As interesting as that is to me, what really caught my attention is how unfazed Kora was by the whole incident. I can imagine her trying to figure out why everyone was making such a big to-do.
After she hopped out of the net, she walked away without seeming particularly stressed. Many dogs would be completely freaked out by the experience, but Kora appeared remarkably well adjusted and stable. Her behavior did not suggest she was traumatized or even upset by her ordeal.
With an attitude like that, I suspect that “Kora the Explorer” will continue to have interesting adventures!

These dogs don’t act quite like other dogs
April 20 2016
When people accumulate animals in large enough numbers that the basic needs of those animals cannot be met, it’s called hoarding. Rescues of dogs from hoarding situations often make the news because the conditions are generally horrific—unimaginably unhealthy and unsanitary. There is usually significant malnutrition and disease, and death is common. Whenever possible, dogs rescued from such situations are nursed back to health and adopted into pet homes.
Their physical health can recover to varying degrees depending on the dog, but what about their behavioral health? There are many anecdotal reports of abnormal behavior in dogs who have been removed from hoarding situations, but the question of how hoarding affects dogs behaviorally has not been well documented. A recent study called “Behavioural characteristics of dogs removed from hoarding situations” addresses this issue by investigating how previously hoarded dogs who have been rehomed differed behaviorally and psychologically from a comparison group of rehomed pet dogs.
Dogs for the study were recruited with notices in newsletters of various rescue and shelter organizations seeking qualified dogs. To be included in the study, a dog had to have been removed from a hoarding situation. The authors of the study defined a hoarding situation as “a living environment where a person or persons accumulate animals in numbers that exceed the person’s abilities to provide for the basic needs of the animals, resulting in animal suffering”. The study included 408 dogs who had been rescued from hoarding situations.
The guardians of the hoarded dogs filled out the highly detailed Canine Behavioral Assessment and Research Questionnaire (C-BARQ), which was developed to measure various behavioral characteristics of dogs. The C-BARQ is a standard research tool used to compare the behavior of different groups of dogs.
The control group of 11,277 dogs came from the C-BARQ database and consisted of dogs of similar age and breed. All of the control dogs lived in homes with people who were not first time guardians. This was done to match the study group; fewer than 10 of the hoarded dogs were with first time guardians, a factor which has been shown to influence behavior.
Not surprisingly, many behavioral differences existed between the two groups. Dogs from hoarding situations were more fearful and more sensitive to touch than the control dogs. They showed more behavior associated with attachment, attention-seeking and separation anxiety. They exhibited a greater frequency of urination and defecation when left alone, destructive chewing, submissive urination and repetitive behaviors.
Dogs rescued from hoarding situations were less trainable and less aggressive. They were less likely than the control dogs to be overly excitable or energetic. They had a lower probability of being persistent barkers, of chasing small animals, or of exhibiting rivalry for resources with other dogs. They were not as likely to roll in foul-smelling material or to chase their own tails compared with dogs in the control group.
To sum up, there were substantial behavioral differences between dogs who had been rescued from hoarding situations and dogs with more typical life experiences. It’s easy to be dismayed when reading about the behavioral abnormalities of dogs who come from hoarding situations.
There’s good news, though, and I always like to look for the bright side. Many of these dogs can be placed in loving pet homes. Also, the more we learn about their atypical behavior, the better equipped we are to help them recover and the more motivated we are as a society to prevent such damaging situations in the first place.
Please share your experiences if you have adopted a dog who previously lived in a hoarding situation.

Detection dog essential for research success
April 13 2016
For three years, scientist Chris Bugbee of Conservation CATalyst has been studying a jaguar named El Jefe, first with support from the University of Arizona and now from the Center for Biological Diversity. El Jefe is about seven years old and the only wild jaguar known to be in the United States. Most members of this species live further south, in Mexico and in other Latin American countries, but El Jefe has spent at least three years in the Santa Rita Mountains in southern Arizona. Jaguars are notoriously elusive, rarely seen and can have territories that cover hundreds of square miles, so the study of El Jefe represents a major success story. He’s not, however, the only animal associated with this study who is a success story.
The other one is a female Belgian Malinois named Mayke, who is a working detection dog. She has been trained to bark when she finds jaguar scat, which she can distinguish from the scat of other large cats. (Mayke is also trained to bark when she finds the scat of ocelot, another species of wild cat.)
Mayke was born to do scent work, coming from a program in Germany that has successfully bred many dogs for this purpose. Like her close relatives from the same lines, she has a great nose, can handle heat and is both trainable and intelligent. Even with that background, her first assignment was not a good match. She was originally placed as an explosives detection dog, but she couldn’t handle working around big trucks or gunfire. Those stresses upset her to the point that she was unable to perform the work she was trained to do, but she excels in the wide open, remote spaces where El Jefe lives, and where both dog and jaguar have been videotaped.
Detection dogs can be trained to find a huge range of things from explosives to drugs to people to invasive snails, so why was Mayke trained to find jaguar scat? The answer to that requires an understanding of how scientists view the excrement of their study animals. As a friend of mine who studied patas monkeys in Africa once said, “Most people think of poop as just poop. I think of poop as information.” (FYI, I paraphrased in order to maintain our PG rating.)
Scat is a major resource for people studying wild mammals, but it’s hard for people to find, especially when the animal in question is a jaguar and can travel 30 miles a day. Luckily, dogs are not held back, as people are, by pathetic noses and tiny olfactory lobes. A trained dog can sniff out scat, and therefore allow humans to learn so much more about an animal than would be possible on our own.
Thanks to Mayke and her trainer, biologist Chris Bugbee, it has been possible to map out El Jefe’s home range, learn what he’s eating, figure out a number of places where he likes to bed down during the day, and study his DNA. Mayke found the first genetically verified jaguar scat in the US, which is a big deal because the jaguar has not always been in this part of its historical range. It’s because of Mayke’s work that scientists have been able to place camera traps in places that El Jefe is likely to visit. The jaguar has been photographed and videotaped over a hundred times in the last three years. The understanding of El Jefe’s location and behavior, made possible by Mayke’s unique contribution to the project, have shown that El Jefe is a resident male who lives in Arizona.
According to Randy Serraglio, a conservation advocate with the Center For Biological Diversity who has studied jaguars for years, this is important because people and organizations who are reluctant to use any resources to protect him tend to refer to him as a “solitary wandering male”. That implies that he is just a vagrant temporarily lost and visiting the US. This is a nonsensical classification because males of this species are always solitary except briefly during mating. Females are also solitary except during mating and during the short period they have young with them.
Jaguars are native to Arizona. Both males and females were living and breeding in the area until people shot and poisoned them out, beginning in the early 1900s. The interest in El Jefe is helping to protect 764,000 acres of critical habitat in southern Arizona, and making it more likely that recovery efforts can re-establish a jaguar population in the area. The area is at risk of great damage to wildlife, water and the attractive landscape because of a proposed copper mine. There are many reasons to reject this environmentally damaging project, and El Jefe’s large territory is one of them.
With such a rare species, it’s important to keep as many potential breeding animals in the population as possible to maintain the genetic diversity. Previously, a male named Macho B who spent time in Arizona and was photographed there, returned to Mexico to breed, and it is likely that El Jefe is also a part of that same population.
Arizonans are quite attached to him already. That is especially true of the kids who named him. Children at Valencia Middle School in the Tucson area, whose mascot is the jaguar, picked his name. El Jefe (Spanish for “The Boss”) was the overwhelming choice in the vote among the five names that were finalists.
Perhaps the most important part of Mayke’s contribution to the study of El Jefe is that she enables scientists to learn about this jaguar in a non-invasive way. They are able to get an amazing amount of valuable data without bothering the cat. This matters for any species, but it’s especially critical when working with rare animals. Sadly, there are cases of jaguars being injured or killed because of attempts to radio collar the animal (to monitor the animal’s position) and a bad reaction to the tranquilizer. Mayke can locate signs of the animal’s presence and allow scientists to collect data without any such invasive techniques, which eliminates the risk associated with other methods of study.
When I asked Bugbee if there was anything else he wanted to share with me about Mayke, he answered, “Just that she’s a success story—even if you ignore that she’s found the first genetically verified jaguar scat in the US—because she found her confidence and came into her own.” They’ve been working together for three years and have a close relationship. Bugbee knows her well and understands her behavior. He knows the different ways that she reacts to various wild animals. If she finds scat from a puma, she pees on it. If she detects fresh deer scent from the glands in their feet, she points—holding one paw up and leaning in the direction of the deer. She also has her own unique responses to bobcats and bears.
Bugbee talks about her with great affection and respect, sounding like both the professional trainer he is and a loving dog guardian like any other, saying, “I wish I knew all of the things she picks up on. It would be incredible,” and “She’s a good dog. I like her.”

Experience with relevant objects has no effect
April 11 2016
Anyone whose dog loves to get into the garbage for a trash party or is better than Houdini at escaping from a crate knows that dogs are problem solvers. In fact, their ability to solve problems is an active area of research, and the results are not always intuitively obvious. (That’s the way that scientists express what other people might say as, “Whoa! That’s not what I expected!”)
In the study, “Inhibitory Control, but Not Prolonged Object-Related Experience Appears to Affect Physical Problem-Solving Performance of Pet Dogs”, researchers studied how two factors relate to how well dogs solve problems presented as physical tasks. Specifically, they wanted to know whether the ability to inhibit themselves was correlated with increased problem solving ability and whether experience with objects relevant to the problems made a difference. These two variables were chosen for investigation because there is evidence that they are both important in problem solving ability across a range of species, including humans.
In order to address these questions, they recruited 63 Border Collie puppies in pet homes and studied them over a period of three years. Each dog was randomly assigned to one of three groups that differed in their experiences with physical tasks.
The first group (enrichment group) received toys that gave them the opportunity to learn about the physical effects of gravity, attachment, and support and also a set of toys that required attending to a size differential between objects to access a treat. The second group (manipulative group) received toys that gave them the same opportunity as the first group to manipulate toys, to push and pull on handles and other parts of the toys, but which did not teach them about the effects of such actions or the importance of relative size. The third group (control group) had only the typical toys used by guardians for stimulation, such as ropes, balls and various rubber toys. The dogs in the experimental and manipulative groups (but not in the control group) took part in a string-pulling study that provided an additional educational experience about the physical effects of their actions.
All dogs, no matter which experience group they were in, were taught three inhibitory tasks. One was being required to wait for permission before taking a treat on the floor in front of them. (This task is often called “Leave It” though some people using this cue never allow the dog to take the treat he was told to leave.)
The second involved the opportunity to obtain a treat from underneath each of two transparent cups turned upside down. The catch was that there were three cups and the dog would only be permitted to knock over two of them. He had to avoid knocking over the empty cup, as the final cup was made unavailable after the dog had knocked over two cups. This is very hard for dogs, especially if the empty cup is in the middle between the cups with treats.
The third task involved the dog being caught by his leash on something like a tree or a lamp post. The guardian would call the dog, but the dog had to first move away from the person in order to untangle himself.
To assess dogs’ level of inhibitory control, they were tested on each of the tasks after a month of practice and scored on a scale of 0 to 2, which 2 representing the highest level of inhibition. This study did not distinguish between learned and inherent levels of inhibition, but simply looked a dog’s ability when tested to control himself in the various tasks.
To sum up, dogs were given one of three levels of experience with objects and their levels of inhibitory control were assessed. They were then tested with four problem-solving tasks. The problems were all designed to be difficult in order to detect potential improvement based on experience. (If the tasks were too easy, researchers would be unlikely to detect any role of experience in dogs’ ability to solve the problem.)
One main result of the study is that there was no difference found in the problem-solving abilities between the three groups of dogs. That is, success at solving the problems was not related to whether a dog was in the enriched, manipulation or control group. Another result of the study was that dogs’ inhibition scores were related to their performance in two of the problem-solving tasks, but not the other two. Of the two tasks in which performance was related to inhibition, one task was positively associated with success (high inhibition predicted success at solving the problem) and the other was negatively associated with success (a low level of inhibition predicted success at performing the task correctly).
The dogs in this study did not exhibit the ability to transfer knowledge about physical rules learned in one situation to another, similar situation. The researchers conclude that dogs do not generalize from one problem-solving task to another. They hypothesize that dogs approach each problem as a novel task unrelated to others that they have already solved.
I’m curious about these conclusions because of my own experiences observing dogs. I don’t have data on canine problem solving, so my surprise about this study’s results only reflects my anecdotal observations. It seems that dogs who understand how to get food from one style of Kong or toy have an easier time figuring out similar puzzles. It also seems that once a dog has solved the mystery of one “secure” trash can, others are quick to be defeated by that same dog. Perhaps experience only matters with highly similar tasks, or when the task is presented in the same location. Another possibility is that if the motivation to solve the problem is high enough, a dog will perform at a higher level. Kongs and trash cans may provide more motivation than a puzzle in a lab setting. All of these variables would be interesting to explore in future studies. Such work is incredibly intensive and time-consuming, and I applaud these researchers for investigating canine problem solving abilities in a long-term, controlled experiment.
Do the conclusions of this study match your expectations?

We can all enjoy Canada’s favorite sport
April 7 2016
Playing is an important part of being happy, and Crusoe the Dachshund has this part of his daily routine in order. In this video, he is playing hockey (or some variant of the sport) with his friend Oakley, who is also a Dachshund.
So many aspects of this video make it fun to watch. There’s the fact that it has dogs in it, which is of course the most important piece. There’s also the whimsical music, the anatomy-enhancing uniforms and the bouncy behavior of the dogs. The skillful editing is a big part of what makes this video so entertaining. My favorite moment is at about six seconds in when one of the dogs looks to his right as though he really is on the ice monitoring the positions of the other players in order to plan his next move.
Crusoe the Celebrity Dachshund has many other entertaining videos, if you ever feel the need for a little canine cheer.

Dogs may need a break from each other
April 5 2016
“I haven’t been more than 30 feet away from him in almost nine weeks!”
That was my older son’s answer when I asked the kids why they were uncharacteristically cranky with each other. It was a fair answer because it was almost literally true. When we spent all of last summer in Europe, it was a lot of family time. Only my husband, whose work was the reason for our travels there, spent some time away from the rest of us.
I know better than to allow that degree of excessive togetherness between dogs in the same family, and I was a little chagrined to realize I had made such a mistake with my human family. Oops. Even dogs who adore each other and are truly the best of friends benefit from some time apart. Absence makes the heart grow fonder. Unless your dogs are the rare exception because they are emotionally incapable of being away from one another, some quality time apart can be advantageous.
It doesn’t have to be a lot of time; I’m not suggesting you adjust your life so that your dogs have hours of separate activities each day. Even one walk or activity a week, or a couple of separate 15-minute play sessions can go a long way. It only takes a short break to prevent small irritations from building up. Those little stresses may not be obvious to us, but dogs can still get on each other’s nerves. Most dogs adjust and there is no problem, but we can help them enjoy life just a bit more with a change of pace involving time away from each other.
Many people swear that their dogs hate to be apart, but in many cases, the issue is not being apart, but being left behind. If more than one person lives in your home, it’s easier to work through this by having each person take one of the dogs to do something at the same time. If you are the only human in the family, then a good plan is to leave something fun and tasty to chew on with one dog while you go somewhere with the other dog.
If this is a challenge for your dogs, it’s a good idea to start with very short separations so that you can teach each dog to be comfortable being left alone. It’s a good skill to have in just case one dog becomes ill or injured and you have a forced separation on your hands.
If you have a multi-dog household, do your dogs have time away from the other dogs in the family?

It’s now legal to break into cars to rescue pets and people
March 31 2016
The governor of Florida just signed a law making it legal to break into a car to rescue a person or a pet who is “in imminent danger of suffering harm.” It applies to vulnerable people and pets (including cats and dogs), but does not apply to farm animals. Many people and pets die each year because they have been left in overheating cars, so this law could save many lives. It is especially important in a hot southern state like Florida with the summer months approaching.
The law specifies procedures that must be followed in order for a person breaking into a car to be protected from civil liability for damage to the vehicle. If you are trying to help someone in danger, here’s what you should know about the law. It is required that you check that the car is locked before breaking in. If you do break in, the law requires that you do so with the minimum force necessary. You are required to call 911 or law enforcement before or immediately after rescuing the person or pet from the car, and you must stay with the rescued pet or the person until first responders arrive.
I’m delighted to know that Floridians are now protected by this law if they see an individual in danger in a car and choose to act. Many people would rescue the pet or person regardless of the risk to themselves, but it’s far better to give legal protection to such potential heroes.

Accepting them is a lifelong process
March 30 2016
Dogs learn to be comfortable with the world through experience. Some dogs take most novel things in stride while others struggle to deal with anything different. Behaviorally healthy, well-socialized dogs have an easier time handling the unexpected than dogs who had rougher starts in life or are naturally less go-with-the-flow.
Learning to cope with new experiences is a lifelong process because there are an infinite number of them. For example, few dogs have had to deal with a child doing handstands, but Marley is one of them. He is accepting, though not particularly thrilled, about this activity. Here he is as my son wanders around him while walking on his hands. (Normally I encourage my son to be thoughtful of the dog and do his handstands at a greater distance from Marley, but I needed a video . . . )
Two factors may explain Marley’s lack of reactivity. One is that Marley is generally not reactive to anything. Sure, he gets pepped up when food or a walk are in his immediate future, and when he sees his guardian or any dear friend after a long absence, he is enthusiastic, but that’s about it. He does not react to popping balloons, power tools, crowds of people, bikes, skateboards or children giving him love. The other factor is that he has been around my son doing handstands for a number of years now, and it probably seems reasonably ordinary to him.
It would be extraordinary for any dog to be relaxed when seeing a child doing handstands for the first time. I once observed an extremely well-adjusted dog startle when he experienced this, presumably for the first time. Several years ago, my son was doing a handstand by the baggage claim area in an airport. (Don’t judge. If you’ve never taken an active 8-year old on a 10-hour plane flight, you may struggle to understand why I said yes when he asked if he could do a handstand. Like dogs who have not had a chance to exercise, my son was in desperate need of some activity.)
Regrettably, I failed to notice that a drug-sniffing dog was in the area, and when the dog came near us and saw my son, that dog visibly flinched. Thankfully, my son noticed and came down from his handstand just as I was telling him to do so, AND the dog’s wise handler immediately turned the dog away from us. Once he was at a good distance from us, the handler cued the dog for a sit and a down, which I suspect was a purposeful attempt to calm him down. I can imagine the handler’s despair at thinking his dog had been taught to deal with so much—people with canes or wheelchairs, kids running around and screaming, crowds of people in all manner of dress and carrying every large or awkwardly shaped item—only to have his dog confronted by the sight of a child walking on his hands.
From the dog’s and the handler’s point of view, it’s certainly possible to consider this bad luck. On the other hand, it was an opportunity to be exposed to yet another new experience and learn to accept it. It served as a reminder to me that no dog’s training and exposure to the world is ever complete. Every dog, even a highly trained working dog, still faces new experiences throughout his life.
Has your dog faced something so unexpected that you never thought to expose him to it on purpose?

It’s not about the breed!
March 25 2016
Not a week goes by that I don’t get asked what I think are the most dangerous kinds of dogs. If what I do for a living comes up, this question often does, too. And when people say “kind” they are typically talking about breed. When I answer that the breed doesn’t have anything to do with it, people are usually skeptical, but there is consensus in the field of canine behavior about this.
Recently, I read a blog post called “The Five Most Dangerous Types of Dogs in the World” that sheds light on what types of dogs are dangerous. It makes clear that we need to pay attention to individual dogs and specific circumstances rather than the dog’s breed. According to this post, the five most dangerous types of dogs are:
Untrained dogs. If a dog has no boundaries, and has never been taught how to behave, he is more likely to injure someone, perhaps by accident.
Fearful dogs. Dogs who are scared or nervous may panic and act aggressively in order to protect themselves. Being afraid is at the root of more canine aggression than any other factor.
Unpredictable dogs. If a dog’s behavior is confusing and does not follow any obvious pattern, it’s easy to be taken off guard by their actions or inadvertently do something that upsets him.
Tired or sick dogs. Just like people, dogs are not at their best when they don’t feel well and most would prefer not to be bothered. Dogs don’t have many ways to let us know they want to be left alone. They sometimes resort to a growl, snap or bite, especially if they’ve already tried to walk away and go off by themselves, and that didn’t get the message across.
Unfamiliar dogs. Not all dogs consider everyone a friend immediately. Lots of dogs need time to warm up to new people and don’t like to be treated as a long lost friend within five seconds of being introduced.. Treating an unfamiliar dog like your best friend can be off-putting to some and lead to aggressive behavior. If you adore all dogs, it’s hard to remember that the feeling of love at first sight may not always be mutual.
There are plenty of dogs in each of these categories that are not dangerous in the slightest, but it makes sense to consider these potential risk factors and act accordingly.
