Anxious Behaviors Linked to Gut Dysfunction in Dogs

Dr. Jason Gagne, board certified veterinary nutritionist, joins host Laura Reeves for a deep dive into dog food feeding trials, anxious behaviors linked to gut dysfunction and more.

“It’s one thing to open up the AAFCO book,” Gagne said. “The Association of American Feed Control Officials who set this model bill, as it’s termed and says you need this much zinc, you need this much selenium and so forth. Then pet food company XYZ, whoever that may be, goes ahead and puts that much in or hopefully a little bit more to meet those requirements.

“It’s another thing to actually be the company (Purina) that does these feeding trials. Again, as I mentioned before, we’re obtaining these ingredients, we’re formulating our diets. We have very tight control over our ingredients specifications and have very high standards for who our suppliers are. But it’s another thing to then take that diet that you make and feed it out to a colony of dogs and we do do that and we’re proud of that.

“The purpose of doing that and having that colony is to feed these diets. Because when we do that, we can measure the digestibility of our diets. We can assess the fecal quality and the fecal score, which I think is important to a lot of breeders and sporting enthusiasts. And we can even assess the performance on the diet.

“It’s not just important to meet the AAFCO requirements, but it’s more important really to optimize those recommendations for the betterment of the dog, right? We put those diets out there on the market after we’ve assessed, hey, we put this in the diet, we want to make sure it’s actually in the diet. We can analyze the diet itself, but then again, we’re analyzing what’s going in and coming out of the dog as well.

“This microbiome, what else is it doing? It’s actually been linked to behavioral issues as well when it goes out of whack, that dysbiosis as you mentioned earlier.

“We actually did do a study with dogs displaying anxious behaviors, and paired it with physiologic as well, so salivary, cortisol and we also had Holter monitors on them for heart rate. We were able to show that when the dogs were being supplemented with the bl999, they (had) a decrease in barking, jumping, spinning and pacing, which was anxious behaviors that they were displaying, versus when they were on the placebo.”
