The Labs have a problem. Actually, some Labs have a problem. It's in their genes: In 2016, a group of researchers at the University of Cambridge discovered a genetic anomaly in a small group of overweight Labrador Retrievers (1). Specifically, the modification is a short deletion sequence in a gene called POMC. The presence of … Continue reading Do These Genes Make Me Look Fat?

Does Your Dog Play with His Food?
Most people have heard the admonition "Stop playing with your food!" at some point during their childhood. It is rare to hear the dog version of this rebuke, however, especially if you live with Golden Retrievers (or Labs......). When the food is only in the bowl for 30 seconds, there is little time for playing … Continue reading Does Your Dog Play with His Food?
The Raw Deal
I have avoided writing this essay. The reason is that, contrary to how it may on occasion appear, I generally do not seek out conflict. Considered debate about scientific evidence and civilized discussions? Yep, enjoy those. However, the acrimony and polarization that frequently accompanies internet discussions about how best to feed dogs? Avoid those like … Continue reading The Raw Deal
Tastes Like Chicken
In recent years, dog owners have started to demand more transparency from pet food manufacturers (a needed change, in my opinion). Many are interested in selecting new types of foods for their dogs and prefer products that are less highly processed. In direct response to these trends, nutrition researchers have been studying the ingredients that … Continue reading Tastes Like Chicken
A Few Raw Facts
Raw feeding has increased in popularity in recent years. While still a small portion of the pet food market, raw foods are definitely here to stay. Perhaps more so than any other type of feeding regimen, dog owners who feed raw are highly dedicated to this form of feeding. To test this premise, try separating … Continue reading A Few Raw Facts
Mind Your Peas and Potatoes
The source and quality of a food's protein sources are important features to consider when selecting a dog food. Dog folks who care about these things often agonize over how to differentiate among foods in terms of both protein level and quality. These concerns are justified because the protein ingredients found in pet foods vary dramatically. … Continue reading Mind Your Peas and Potatoes

A Taste for Meat?
The issue of how to classify the dog and how to best feed dogs continues to be a highly controversial topic among dog people. If you doubt this, just try posting this statement in a dog feeding chat group: "Dogs are omnivores and can thrive on a wide range of diet types." Good luck surviving the night. I discuss the current science regarding the … Continue reading A Taste for Meat?
Digestibility Matters
In "Dog Food Logic" and "Only Have Eyes for You", I have emphasized (okay, some might say "harped upon") the need for pet food companies to provide digestibility information to consumers. It is not a difficult value to determine and most pet food companies already conduct feeding trials that measure this (yet keep the results to themselves). As … Continue reading Digestibility Matters
What’s in Your (Vegetarian) Food?
Here we go again. It appears that there may be more than what dog owners expect to find in vegetarian dog food. Hold the Spam, Please: Before all of the "Dogs are Carnivores (and a pox on your mother if you think differently)" devotees begin posting comments (in all caps ) that dogs should NOT be fed a vegetarian diet in the first … Continue reading What’s in Your (Vegetarian) Food?

Before food purists get up in arms over this topic, consider that numerous human cultures have historically viewed insects as acceptable and even highly desirable food items. And today, our ever-expanding human population and the increasing need for sustainable sources of food have led to increased consideration of insects as food in almost all human cultures. … Continue reading Want Flies with that Shake?
How Reactive is Your…….Lysine?
I imagine that the word "reactive" caused most readers to think of this: However, what we will actually be talking about is this: Yeah, not quite so dramatic, I admit. However, the reality is that the amount of reactive lysine present in your dog's food is much more likely to have an impact on his health … Continue reading How Reactive is Your…….Lysine?
Dog Food Marketing – Science Weighs In
Marketing researchers know a lot about advertising strategies that successfully increase sales. This is no less true for pet foods than it is for any other consumer goods. Some of the more obvious approaches to attracting dog owners to a particular brand are advertisements that appeal to our emotional attachment to dogs, capitalize on our desire for expert … Continue reading Dog Food Marketing – Science Weighs In
