Explaining a Glitch in Fetch
It makes sense after all

We were playing fetch with Super Bee, a friend’s dog, and her unpredictable behavior was making the game less fun for us. All was smooth when we threw the ball and she went to retrieve it. One hundred percent of the time, she gleefully ran it down, picked it up, and brought it back. The difficulty occurred in the transfer of the ball back to us so that we could throw it again.

Though she reliably dropped the ball and let it fall to the ground, she sometimes darted at the ball and snatched it up again, only to drop it once more. She didn’t do it every time, but she did it enough that it was a problem. Besides interrupting the flow of the game and being a little annoying, this glitch in the game created a risk that she would hurt my sons if either of them reached for the ball at the same time that she went for it.

I adjusted the game so that I was always the one to pick up the ball, and then I handed it to my sons alternately to throw it. I only reached for the ball after a pause of a few seconds, which seemed to be after she had made her choice about whether to go for the ball again or let me pick it up so it could be thrown for her. It didn’t guarantee my safety, but I managed to avoid trouble. I also noticed a pattern.

Whenever the ball stayed in place on the ground or rolled toward her, Super Bee let me pick it up without making an attempt to take it again. However, if it rolled away from her, she charged at it and grabbed it in her mouth. My best guess is that when the ball rolled away from her, she acted as she did when the ball had been thrown—she retrieved it. The ball was moving away from her, which seemed to be the stimulus for that behavior. It was as though she was on autopilot and couldn’t stop herself from retrieving a ball moving away from her.

Super Bee is an enthusiastic and possibly obsessive fetcher who can’t help but chase after a ball when it is thrown. Even when she is hot and tired enough that she might rather rest in a cool spot, if someone throws a ball, she will go after it. When we play with her, we make sure to stop fetch games long before she becomes fatigued or overheated.

Now that we understand her tendency to “retrieve” balls that roll away from her after she drops them, we only reach for balls that don’t do that. If a ball is moving towards her or is not moving, it’s safe to pick it up. (Another option would be to cue her to drop the ball directly into our hands, which would eliminate the possibility of it rolling.) Taking the unpredictability out of the game makes it more fun and safer, too. Because we understand what is happening, my sons and Super Bee can play fetch without my intervention (though I still supervise!) When it seemed like she was grabbing the ball again instead of letting us throw it, her behavior seemed irksome. Knowing that she is simply retrieving a moving ball because she can’t help it, it’s easy to find the behavior interesting and to wait patiently until she drops it again.

Does your dog ever do this?

Do You Play Bow to Your Dog?
Starting play the canine way

If you want to extend a special kindness to your dogs, consider communicating in ways that naturally make sense to them. Play signals are one opportunity to do this. When dogs want to play, they let others know with play signals, which they use to get play started and to keep it going. These signals can mean different things, but the message is always aimed at keeping play safe by telling other dogs that intentions are playful. A play signal tells another dog “I want to play."

It also communicates that even if the behavior to follow is borrowed from other contexts such as fighting or predation and involves biting, chasing, shaking, or slamming into one another, it is playful in nature. There is no intent to cause harm. Using play signals to communicate makes it less likely that a dog’s actions will be misinterpreted, which can cause play to escalate into aggression.

By far the most common play signal is the play bow, which consists of a dog getting down on her elbows with her back end higher than her front end. This posture is often assumed abruptly, as though the suddenness of the movement is part of the signal as well.

Though the play bow is a universal invitation to play among dogs, people can do it, too. A human can imitate this action by getting down on all fours, putting both elbows on the ground and leaving the bottom up in the air. Dogs usually perform play bows in a springy, fast motion with a bounciness to it, so if you want your play bow to be as well-received as possible, try to mimic that rather than calmly moving into the posture like you are doing flow yoga.

A modified play bow for people is possible, too, and it’s a little easier because you can remain standing. All you have to do is lean over from the hips, bend both legs, and spread your arms out at a 45-degree angle. To appear most playful to the dog receiving this signal, go into the pose quickly, perhaps even doing a little jump to go into the pose. Then, do something playful, like run away from your dog to start a chase game.

Many dogs love it when people do play bows, modified or not. I’ve seen dogs whose faces light up when their guardians first play bow to them. I’ve often wondered if seeing their humans perform a play bow makes them happy because there is no confusion—they already know what it means. In any relationship, it’s beautiful to understand and to be understood.

Do you play bow to your dog? If so, how does your dog respond?

Cats Steal Dog Beds
A familiar scene in many homes

In any household, there is bound to be conflict, whether it is between human brothers and sisters who can’t agree on what game to play, dogs who want the same chew toy, or spouses who can’t find a movie to watch that looks good to both of them. When you add in conflicts across species, there are even more opportunities for discord.

People and pets may not feel the same way about a variety of subjects. Is it a colored pencil for a child’s art class or a stick to be gnawed on by the dog? Should the hamster be quiet all night so the humans can sleep, or is midnight to 6 a.m. the perfect time to run a squeaky wheel?

And as for cats and dogs, the big question might be, “Just whose bed is that anyway?” It seems that cats are notorious for making themselves right at home on the dog’s bed, no matter how big the bed is or how small the cat. In this video, a number of dogs of various breeds, ages and sizes must contend with cats who have taken over their bed.

Do you have dog and cat conflicts over beds in your house? Who usually emerges victorious?

Good Dog: Behavior & Training
Behavior Matters: Attention, Please!
Attentiveness matters for safety and convenience.

Ian’s dogs—Maggie, Molly and Jake—display various levels of attentiveness while they’re together on the trail. Maggie looks back every few seconds, as though she’s afraid he’ll disappear. Molly’s mainly interested in Ian when she’s thirsty. Jake checks in from time to time, typically when he’s startled by an unusual sound or comes to a bend in the trail. When Ian calls them, they all run joyfully to him. In response to their names, each pauses and looks toward him, suspending activity while waiting for more information. Each has also been trained to look at him in response to the cue “watch.” Though these dogs have different levels of natural attentiveness, they are uniformly skilled at responding to cues for attention.

Ian can hike with his dogs off-leash, confident that they will pay attention to him if he asks them to, even though at least one and sometimes two of them are less interested in him than in the world around them. Only Maggie consistently gives him her attention spontaneously, but they all attend to him on cue. Spontaneous attention and attention that’s given on cue are both valuable.

Inborn or Learned
Many factors influence the level of a dog’s attentiveness. Some naturally attentive dogs are clingy and some are social butterflies who are just drawn to people. Still others are a bit possessive, treating their guardians as though they are the best bones in the world and need constant attention to maintain their safety. While these traits can be modified, they cannot be created out of thin air or fundamentally changed. Dogs either have this behavioral tendency or they don’t.

Few dogs are as naturally attentive as most of us wish; if yours isn’t, don’t feel bad, don’t feel guilty and for goodness sake, don’t wonder what you did wrong! Your dog, like most dogs, just isn’t inclined that way. For some guardians, that’s a good thing. Plenty of people prefer dogs with their own interests who can amuse themselves and aren’t staring at them expectantly, riveted by their every action.

Relationships
The strength of your relationship has an impact on your dog’s attentiveness. If you have consistently been a source of what makes your dog happy, attention is a likely side effect. A lot of love between the two of you and a strong history of fun together make paying attention to you worthwhile for your dog.

While a strong relationship can help with attention issues, I’m not suggesting that a good relationship will guarantee a high level of attentiveness: it won’t. It’s just one piece of the puzzle, and if your dog is not highly attentive in all situations, it certainly doesn’t mean that the relationship is flawed or in any way lacking. It just means that for whatever reason, your dog is focusing on other aspects of the environment.

Many people find that their dogs are so engrossed in the environment and all its wonderful smells that getting them to pay attention outdoors feels like swimming upstream. Though such “nose to the ground” dogs are indeed among the most challenging when it comes to working on attentiveness, many of them are actually attending to their people without obvious signs of doing so. It’s common for those with dogs who are particularly responsive to the environment to note that their dogs always know where they are when they’re out and about. However, the dogs’ top priority in that context isn’t interacting with people, it’s interacting with the environment. They tend to show their affiliation in other ways at other times, and that’s where the strength of the relationship is more obvious to the casual observer.

Many factors affect your relationship, including your respective personalities and your interactions over time. If your dog associates you with treats, enjoyable training, massages, outings, toys and games, you’re more likely to have his attention. In the best of relationships, there’s also an intangible quality: some individuals hit it off in an indefinable, magical way. Strong bonds of love are often made of those special and inexplicable connections.

If a relationship is damaged or not very strong, the dog may give more attention to someone else. Some of the saddest cases in my practice have been those in which the dog isn’t that interested in the person. For example, a man moved back in with his mother and spent tons of time walking and playing with her dog. The dog adored him, but took virtually no notice of the woman. Multiple times each day, she cued him to hug her, which meant jumping up on her, putting his paws on her shoulders and staying that way while she squeezed him. She wanted affection from the dog, but the dog clearly disliked it.

We improved the relationship between the woman and her dog by having her engage with the dog in ways that were fun and satisfying to him. Once she had developed the habit of taking him out for walks, playing fetch with him daily and massaging him afterward, he was drawn to her, and the amount of attention he gave her increased accordingly. She stopped asking him for hugs, and he spontaneously cuddled up beside her. She no longer had to beg for his attention or affection.

Putting Attention on Cue
“My dog pays me no mind when she’s outside off leash.” “My dog is always blowing me off.” “She knows she’s supposed to listen to me, but she ignores me if anything else is going on.” These are all common complaints from people struggling with getting their dogs to pay attention on cue.

The problem many of us have with a dog who is not responsive to cues, especially outside, is not so much a matter of devotion but of training. For most dogs, learning a “pay attention” cue in the face of a whole world of wonder is essentially a difficult, high-level trick and must be taught as such. Yes, some dogs learn this quickly and thoroughly without too much trouble, but that’s unusual. For most dogs, expect topquality responses only after consistent, long-term training efforts.

In the larger scheme of things, a cue to pay attention is essential because it is the basis of all training. You can teach a dog just about anything if you have his attention, but it’s virtually impossible if you don’t. Asking for a dog’s attention is a top priority for professional trainers, which is why it is often the first skill taught in classes or private lessons.

This is especially valuable for dogs who don’t frequently offer their attention spontaneously. For naturally attentive dogs, attention training is largely about putting a behavior that frequently happens on cue. Teaching dogs to give attention when they don’t consistently offer it on their own requires more time and effort because you have to teach the behavior and associate it with a cue.

The two most common cues for attention are “watch” and the dog’s name. “Watch” tells a dog to look at your face, and it’s a great way to keep a dog from paying attention to things that cause him to act in an undesirable way. Saying the dog’s name lets him know that he should pay attention to you and wait for more information. Once you have your dog’s attention, it’s easier for him to respond to other cues, including “down,” “stay” and “come,” or simply to follow you in a new direction on a walk. It’s important to reinforce these behaviors so your dog’s glad he did what you asked. If he learns that he’ll receive a treat or have a chance to play for giving you his attention in response to the cue “watch” or to his name, he will be more likely to give you his attention when asked in the future.

Paying attention will be easier for your dog in some contexts than in others. Typically, dogs are more likely to pay attention inside than outside, and when there are no distractions—no squirrels or cooking aromas on the breeze.

Like any other skill, giving attention on cue requires practice and takes time to teach. Gradually working toward giving attention in increasingly challenging environments is a good strategy. Improving the relationship so that the dog is more inclined to pay attention will also improve your dog’s responsiveness to you.

Ideally, dogs keep track of where their person is. It’s a sign of maturity to be able to sniff in the grass, romp with a canine buddy and still occasionally check in. Though dogs with certain natural tendencies are more disposed to do this, others can be trained to act the same way.

When I’m teaching dogs to exhibit this behavior, I do it in places that allow them to be safely off-leash, where they can wander and sniff to their hearts’ content. When the dog is in his own world and not attending to me at all, I position myself so that I can see the dog but he can’t see me. When he looks up and seems just a little concerned, I call him to come, reinforcing him for his successful search. (If he becomes stressed, I come out of my hiding spot so he can see me, and still reinforce him for coming to me.)

This is a good way to perfect recalls and teach your dog that it’s wise to keep track of you, but it only works with dogs who are connected enough to care when they think for a moment that their person is lost. It is not helpful with aloof dogs or those who are completely unperturbed by your absence, and it’s just cruel to disappear on a clingy, nervous dog. Reserve this technique for those who are stable enough to handle your absence and connected enough to care—which, fortunately, is the majority of dogs.

Remember, when we talk about our dogs paying attention to us, we are really talking about two things: spontaneous attention and attention given on cue. There are many ways to improve both kinds of attentiveness, but that doesn’t mean you can change a dog’s essential nature. All the training in the world isn’t going to turn an aloof and independent dog or a dog who is wildly distracted by the smells of the great outdoors into one who is compulsive about checking in and never lets you out of sight. It is, however, possible to teach any dog to respond properly to the cue “watch” and to his name, and to come when called.

It’s also possible, and desirable, to strengthen your relationship with your dog to increase his attentiveness to you. The more fun and satisfying your interactions are, the more likely your dog is to give you his attention spontaneously or on cue.

Making a Case for Dogs’ Personhood

In a recent  New York Times, Gregory Berns, a neuroscientist and the author of the excellent new book, How Dogs Love Us, writes an intriguing and engrossing editorial, “Dogs Are People, Too” (which was the top “emailed” article in the NYT the day it came out!).  Berns and his team at Emory University have been testing dogs, the first of which was Berns’ own rescue dog, Callie, using functional MRIs to measure their brain activity, hoping to decode the canine brain. Unlike other researchers at other universities, the Emory Dog Project was the first to do this and the only ones who perform their research with not only volunteer dogs, but also by following a humane protocol that included  “only positive training methods. No sedation. No restraints. If the dogs didn’t want to be in the M.R.I. scanner, they could leave. Same as any human volunteer.”  Other researchers also use “purpose-bred” Beagles, an abhorrent practice.

What they discovered was rather amazing. As I noted in the book review in Bark’s Winter issue, “Initial findings showed evidence that dogs empathize with humans and have a theory of mind, and by extension, that the idea that you must be a dog’s pack leader is a mistake.”

In his commentary Berns notes, “Although we are just beginning to answer basic questions about the canine brain, we cannot ignore the striking similarity between dogs and humans in both the structure and function of a key brain region: the caudate nucleus.”

In making his case for the “personhood” of dogs Berns explains that, “The ability to experience positive emotions, like love and attachment, would mean that dogs have a level of sentience comparable to that of a human child. And this ability suggests a rethinking of how we treat dogs.” And that we can’t hide from the evidence shown in the MRIs, dogs, and other animals (like primates) do have emotional lives, just like us. In his book he describes that the defining traits of dogs is their interspecies social intelligence, “an ability to intuit what humans and other animal are thinking,” and furthermore that, “ Dogs’ great social intelligence means that they probably also have a high capacity for empathy. More than intuiting what we think, dogs may also feel what we feel.”

It is then perfectly understandable that he makes the case for granting dogs personhood, as he wrote in the Times piece, “ If we … granted dogs rights of personhood, they would be afforded additional protection against exploitation. Puppy mills, laboratory dogs and dog racing would be banned for violating the basic right of self-determination of a person.”

Seeing Previous Guardians
Love in the past and present

Many years ago, I acquired a 2½-year old Lab mix from a family who was rehoming him. The conflicts with their other dog had become alarming and had compromised the quality of life for the entire household. My bond with my new dog formed quickly and was strong until he died and beyond.

It’s phenomenal how well dogs can form new attachments and love so many people throughout their lives. Humans can do that, too, though this is far from common in the animal world. I couldn’t help but notice the happiness my dog expressed when we ran into his original family around town, which happened a few times a year.

Whenever he saw them, he went, for lack of a better term, completely bonkers. He jumped straight into the air like he was on a pogo stick, with all four paws nearly five feet off the ground. His face showed pure joy as he greeted them, and they were much the same in their expressions. Though there was so much love on both sides, they chose to place him in a home where he was not at risk of being harmed by fights with their other, older dog. I’m so grateful for that because otherwise he would never have entered my life.

Though my dog was thrilled to see the people he lived with from 8 weeks to 2½ years of age, he never attempted to stay with them. After each reunion, he invariably returned his attention to me and did not hesitate as we walked away. There were no backward glances and he did not seem confused in any way. Though I can’t know exactly what he felt or thought, I can make guesses based on his behavior. I think he was happy to see the people he knew from the past because he loved them. He also loved me and I believe that he naturally felt more connected to me because we were currently spending time together, sharing a home and a life.

I always enjoyed his reaction to his first family because I liked seeing him happy for any reason. I would have been horrified to see him react to them with avoidance, fear or any other negative emotion. A show of indifference would not have been much better as that would have made me wonder if he would be capable of ceasing to care about me, too. It also made me happy because I could see how much it meant to the family to be honored with an over-the-top exuberant greeting from the dog they loved. It had been a heartbreaking decision for them to give him up for the safety of both dogs. They were overjoyed to see that he still loved them, too, and was excited to see them.

How does your dog react to seeing a previous guardian or a foster family? Or, if you were previously the guardian or foster family to a dog you’ve been able to see again, how does the dog act at the reunion?

What Do You Hear in These Dog Sounds?
All barks are not alike

AS YOU PROBABLY KNOW, your dog’s voice is not like a Bret Michaels concert, pumping out a shower of meaningless noise. Although your dog’s vocalizations might be unwelcome at times, those sounds carry way more information and meaning than any of the former frontman’s power ballads can ever hope to do. Well, maybe not as much as “Every Rose Has Its Thorn.”

In recent years, many studies have investigated the noises made by companion dogs. Now, you (yes, YOU!) can help researchers in a new study where participants listen to and rate different vocalizations. But first, what have we learned about dog vocalizations so far?

Time to Be All Ears

One major finding: dogs bark differently in different contexts, and it’s possible to tell the difference. Sophia Yin, DVM, MS, found that “disturbance barks” (e.g., barks in response to a stranger ringing the doorbell) sound different from “isolation barks” (when a dog is separated from an owner) as well as barks emitted during play. In each context, barks have specific acoustic parameters: where disturbance barks are “relatively low-pitched, harsh barks with little variation in pitch or loudness,” isolation barks are “higher pitched, more tonal and more frequency-modulated than the disturbance barks,” and play barks are “similar to the isolation barks except that they usually occurred in clusters rather than singly” (Yin, 2010 Blog Post). Instead of seeing barks as meaningless noise, pay attention. Banjo might be yipping because he’s alone, or he may have noticed that someone uninvited is climbing in through your second floor window.

Dog barks are full of information, but what about growls? Anna Taylor and colleagues at the University of Sussex studied growling and found that, unlike barks, many acoustic properties of growls recorded in a play and aggressive context did not differ. But aggressive growls were longer than play growls, and play growls had a shorter pause between growls.

While growls are thought to be associated with aggression, remember they can also appear during play, so consider growling in a larger context. Additionally, if you come across a situation where growling could be associated with aggression, don’t freak out. Jolanta Benal, CPDT-KA, CBCC-KA and author of The Dog Trainer on Quick and Dirty Tips, reminds: if you punish a dog for growling, you are essentially punishing a dog for giving a warning. Growling is a form of communication related to emotional or inner states in a particular context. If you want to decrease growling, think about what’s prompting the growling. The growling itself is not a problem.

Many high-profile dog vocalization studies were developed by Péter Pongrácz, Csaba Molnár and Tamás Faragó of the Family Dog Project at Eötvös Loránd University in Budapest. In one notable study, dogs were placed in a room with a bone, and researchers played a recording of one of three growls from a different dog. Dogs responded to the “this is my food” growl by backing away from the bone, and dogs for the most part ignored the “go away stranger” and the play growl because those growls were not relevant to the bone. All growls are not the same, and dogs know it. So let’s try to get on the same page as them.

While we are learning about the noises coming from dogs’ mouths, we still have a way to go. I recently spoke with Monique Udell, an Assistant Professor at Oregon State University and a canine researcher, for an article on dog vocalizations for The Bark magazine (view article here). As Udell pointed out, “Vocal behavior in other species has received a lot of detailed attention. In birds, we’ve looked down to the note sequence and explored tiny variations. Vocalizations are such a prominent feature of dogs, and there is a lot to learn.”

Listen! You Can Help!

Now, back to what YOU can do to advance the science of vocalizations from the comfort of your couch. Tamás Faragó, now a postdoctoral researcher with the MTA-ELTE Comparative Ethology Research Group in Budapest, is exploring how humans perceive emotions in vocalizations. The study asks human subjects (like you!) to listen to and rate different vocalizations on a chart based on how aroused you think the vocalization is and whether you think it’s positive or negative. I promise you will not hear a single note of “Every Rose Has Its Thorn.” Okay, only if you want to. The whole survey takes about a half hour, and as you go along, you’ll you get the swing of it. Check out the details below to participate.

The Gut: The Key to Health
Find the proper balance in the intestinal tract.
Gut is Key to Health

Hippocrates, the father of medicine, is quoted as saying, “bad digestion is at the root of all evil” and “death sits in the bowels.” What Hippocrates likely meant was that the GI tract, or “gut,” is responsible for much more than digesting food; it plays a vital role in creating and sustaining health. Nearly 2,500 years later, scientists are discovering that Hippocrates was right. You simply cannot have a “sick” gut and be truly healthy!

The “gut”, which is made up of the stomach, small intestine and colon (large intestine), is actually a complex microsystem of “good” bacteria, or microflora. While bacteria also live in our mouths, on our skin and in our urogenital tract, more than 70 percent take up residence in the mucosal tissue lining of the gut, which is known as the gut-associated lymphoid tissue, or GALT. The trillions of beneficial bacteria inside the gut comprise a metabolically active organ—the largest immune organ in the body—and are important for a variety of essential functions, including regulating digestion, producing and metabolizing vitamins and other trace nutrients, and protecting the body from infection.

The gut also contains pathogenic “bad” bacteria, such as E. coli. When the balance of good and bad bacteria goes awry, humans and animals can experience a myriad of digestive disturbances, including bloating, constipation or diarrhea, as well as abdominal cramping, surface erosions, and ulcers. But the relationship between gut bacteria and health extends far beyond the digestive system.

For example, gut microflora serves as a significant barrier to infection from outside pathogens, preventing unwanted invaders such as food toxins, toxic chemicals, bad bacteria and fungi from entering our systems. A condition called “leaky gut” arises when the integrity of the gut’s mucosal lining is compromised, causing it to become permeable, or “leaky.” When this occurs, unwanted molecules are allowed to pass through. Since the body recognizes these molecules as foreign, it attacks them. Science is now learning that “leaky gut” likely contributes to a variety of autoimmune diseases, including Type 1 diabetes and autoimmune thyroiditis.

Other conditions linked to imbalances in the gut’s bacterial ecosystem include:

  • Allergies
  • Arthritis
  • Autism
  • Behavioral problems
  • Colon cancer
  • Inflammation
  • Obesity

A recently released study by the Cleveland Clinic exemplifies the important role of gut bacteria. The study found that some gut bacteria produce a compound called trimethylamine- N-oxide, or TMAO, while digesting lecithin found in foods such as egg yolks, liver, beef, pork and wheat germ. The researchers also found that blood levels of TMAO predict heart attack, stroke and death—independent of other risk factors. The fact that gut bacteria can cause heart attack, stroke and death, even in otherwise “healthy” people, is a true testament to their importance!

Obviously, to create and maintain health, we want to keep the gut microflora in tip-top shape. But if the gut is teeming with trillions of good bacteria, what’s the problem?

Many environmental factors can disrupt gut bacteria, throwing the balance between good and bad bacteria out of whack, including:

  • Antibiotics
  • Introducing new foods too fast
  • Poor diet
  • Stress
  • Vaccination

Fortunately, you can help keep your pet’s gut in tip-top shape by giving him probiotics.

Probiotics are live, beneficial bacteria. When ingested in sufficient numbers, probiotics colonize in the gut, thereby supplementing the existing beneficial microflora.

Probiotics can provide many health benefits in pets, including:

  • Aid in digestion
  • Assist with food transitioning
  • Boost the immune system
  • Help manage stress colitis
  • Prevent and manage diarrhea
  • Prevent overgrowth of “bad” bacteria in the gut
  • Promote overall intestinal health
  • Reduce inflammation
  • Replace “good” bacteria destroyed by antibiotics

But don’t just run out and buy any product labeled “probiotic”. The product you purchase should meet strict standards, including:

Contain live bacteria. The product is not a probiotic unless the bacteria are live.

Contain multiple bacterial strains. Different strains of bacteria exert different biological activities. Look for a product containing at least 10 different strains.

Is potent. When it comes to a probiotic, the more potent the better. While some products contain 1 billion beneficial bacteria per serving, I advise looking for a product containing at least 30 billion or more beneficial bacteria per serving.

Is pure. A probiotic is designed to increase gut health. The last thing you want is a product that contains artificial colors, flavors or preservatives, sugar, salt, corn, wheat, soy or other undesirable ingredients.

And please don’t share your probiotic with your pet. An animal’s intestinal tract contains species-specific microflora, so a probiotic that’s beneficial for you isn’t necessarily beneficial for your companion animal. Opt instead for a probiotic targeted specifically to your pet’s species.

Supplementing your companion animal’s diet with a probiotic is a simple, safe and effective way to optimize gut health. You might just be amazed at the positive improvements these “gut bugs” can make!

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.”
