Researchers at the University of Guelph asked 433 dog owners how they feed their dogs, and the raw feeders turned out to be the ones doing extra work.

The Guelph study, published May 20 in Frontiers in Veterinary Science, found raw feeders were about twice as likely to give their dogs fish oil. They were far more likely to add supplements to keep the diet balanced, and they bought less of their dogs' food at the vet's office. The authors read that last finding as a sign that raw feeders distrust veterinarians.

The survey never tested that idea, and the rest of the data describes owners who decided processing matters and acted on it.

The team recruited owners through ads on 15 dog-related Facebook pages in June and July of 2022.

The authors list their own limits: a convenience sample, owners who chose to answer a nutrition survey, a mostly female group and a lopsided split between diets. They also ran many single comparisons, which raises the odds of a chance finding. Read the numbers as a portrait of the owners who answered.

The two groups split on how they shop, supplement and think about food.

Raw feeders also shopped in different places. They were more likely to buy at pet specialty stores and to make food from raw ingredients, and less likely to buy at supermarkets or vet clinics. Their own eating habits and how close they felt to their dogs didn't differ from cooked feeders.

Raw feeders were less likely to say a general-practice vet, a board-certified veterinary nutritionist or a vet tech shaped which food they picked. In the discussion, the authors write that this "may trace back to raw feeders' distrust of veterinarians," leaning on earlier papers that describe raw feeders turning to unverified sources. The survey measured whose advice shaped a food choice, and it included no question about trust.

There's another reading that fits the same numbers. These are owners who already supplement for balance, rate their own nutrition knowledge highly and buy away from the clinic shelf. The clinic shelf is also where the biggest kibble brands sell, and Hill's is now pitching vets first on its new refrigerated rolls.

If your vet has pushed back on raw, the vet said no conversation works better with specific questions than with a standoff.

The paper lists its funding and author ties in full.

Industry chairs are common in veterinary nutrition, and disclosing them is the right call. They're also a reason to separate what a survey measured from how it was framed. The measurements here describe careful owners. The framing describes a trust problem.

Raw feeders in this survey ranked convenience and price below other things. They shopped specialty stores, supplemented for balance, used fish oil at twice the rate and picked their food because it was minimally processed. That's a profile of owners who decided processing matters, and the next step for any of them is buying from verified raw brands that publish their lab results. The survey was built to help the people who sell food and the people who treat dogs understand raw feeders, and it ended up showing the extra work those owners already do.
