It Starts With the Gut And Science Is Finally Catching Up

For a long time, dog nutrition conversations felt incredibly black and white. Feed kibble or feed raw. Pick a side. Defend it aggressively on the internet. Repeat.

Thankfully, both veterinary medicine and nutritional research have started moving toward a much more nuanced understanding of what’s actually happening inside the canine body, particularly when it comes to the gut microbiome.

Your dog’s gut does far more than simply digest food. The microbiome plays a major role in immune function, inflammation regulation, nutrient absorption, digestion, and even behavior through what researchers often refer to as the gut-brain axis. We’re continuing to learn that microbial diversity may be one of the biggest contributors to long-term health, and early life appears to be a particularly important period for establishing that foundation.

That matters a lot to me as a breeder because so much of what I do centers around setting puppies up for long-term success before they ever leave my home.

Emerging research has shown that diet can significantly influence the composition of the canine gut microbiome. A study published in BMC Veterinary Research found that dogs fed raw diets developed significantly different gut bacterial populations compared to dogs fed extruded kibble diets, with notable shifts in microbial diversity and digestive-related bacteria. Researchers found that dietary changes were capable of altering the gut ecosystem relatively quickly, which continues to reinforce just how responsive the microbiome can be to nutrition.

Additional research has continued to support similar findings. In more recent studies, dogs transitioned from kibble to less processed diets demonstrated measurable changes in gut bacteria composition, with researchers noting increased microbial diversity and shifts toward bacterial populations often associated with less processed ancestral diets. While we still need significantly more long-term research in this space, the early findings are incredibly interesting and continue to support what many fresh food advocates have suspected for years, that diet quality and diversity may play a larger role in canine health than we previously understood.

And to be very clear, this is not me claiming raw feeding is some magical cure-all.

It’s not.

Poorly formulated raw diets can absolutely create nutritional deficiencies, especially in growing puppies, and improper food handling creates legitimate health risks. Organizations like Cornell University College of Veterinary Medicine have appropriately emphasized the importance of balanced formulation and safe food handling when feeding raw diets, and I fully agree with that.

That’s why our feeding program at Outlaw Minis is intentional rather than trendy. Our dogs have been raised on raw feeding for multiple generations, and our puppies begin life with species-appropriate nutrition because I believe early development deserves thoughtful consideration across every area of wellness, including what goes into their bodies.

That said, I also believe in being a very normal person about dog nutrition.

Not every family wants to continue feeding raw long term, and that is completely okay. Some families continue raw, some transition to fresh food, and some choose a high-quality kibble that better fits their lifestyle. My role is not to shame anyone into feeding exactly how I feed. My role is to help families make informed decisions while protecting their puppy’s health and ensuring transitions happen thoughtfully.

Because if you’ve ever abruptly changed a puppy’s food and dealt with the digestive consequences, you already know that your puppy will absolutely make their opinions known.

Usually on your carpet.
