Raw Diets for Dogs and Cats: Weighing the Evidence

What Raw Diets Actually Are

Raw feeding — often called a BARF diet (Biologically Appropriate Raw Food, or Bones and Raw Food) — typically consists of uncooked muscle meat, organ meat, raw meaty bones, eggs, and sometimes raw fruits or vegetables. Commercial frozen raw and freeze-dried raw products also fall under this umbrella. The premise is that minimally processed food more closely resembles what dogs and cats ate before domestication.

It's worth understanding the key distinction: home-prepared raw diets are assembled by owners from whole ingredients, while commercial raw diets are manufactured products that may or may not be tested for pathogens or nutritional adequacy. These two categories carry different — though overlapping — risk profiles. The discussion here covers both. For context on how raw compares with another hands-on feeding style, see our home-cooked pet meals overview.

The Case for Raw Feeding

Proponents point to several potential benefits, many of which are reported anecdotally by owners or observed in limited studies. It's important to note that high-quality, peer-reviewed evidence is still relatively sparse in this area.

Some research does suggest that certain minimally processed diets may support digestive health markers, and cats — as obligate carnivores — have a metabolic architecture that is particularly protein-focused. Our article on species-specific nutritional differences explains why this distinction matters when evaluating any diet.

The Risks: What the Evidence Shows

The documented concerns around raw diets are where the veterinary consensus is clearest and most consistent.

Organizations including the American Veterinary Medical Association (AVMA) and the American Animal Hospital Association (AAHA) have published position statements discouraging the feeding of raw or undercooked animal proteins to pets, citing public health and animal health risks. These are not fringe views — they reflect a review of available safety evidence.

Nutritional adequacy is a separate but equally serious concern. Studies analyzing home-prepared raw diets have repeatedly found that the majority are deficient in one or more essential nutrients. Without formulation by a board-certified veterinary nutritionist, owners often unknowingly feed unbalanced meals over months or years. If you're considering supplementing to fill gaps, our guide to pet supplements outlines where evidence does and doesn't support their use.

How It Compares to Other Feeding Approaches

Raw feeding exists on a spectrum alongside other feeding choices. Well-formulated commercial kibble and wet food meet established nutritional standards set by bodies such as the Association of American Feed Control Officials (AAFCO). That doesn't make them perfect — processing does affect some nutrient profiles — but it does mean nutritional completeness is systematically tested. For a direct comparison of those options, see our kibble vs. wet food breakdown.

Cost is another practical consideration. Raw diets — especially commercially prepared ones — tend to be substantially more expensive per meal than standard kibble. Owners drawn to the transparency of knowing exactly what's in their pet's food can achieve some of that goal without raw-feeding risks. Our budget-conscious pet feeding guide covers evidence-based ways to prioritize quality without premium price tags.

Making an Informed Decision

If you're seriously considering a raw diet for your dog or cat, the single most important step is consulting a board-certified veterinary nutritionist (Diplomate of the American College of Veterinary Nutrition). Generic online recipes — even those that appear professionally designed — frequently fail to meet AAFCO nutrient profiles. A nutritionist can formulate a diet specific to your pet's species, life stage, and health status.

Strict food-handling hygiene is non-negotiable. This means treating raw pet food with the same precautions as raw meat for human consumption: dedicated cutting boards, thorough handwashing, and careful management of surfaces and storage. Households with young children, pregnant individuals, elderly family members, or anyone with a compromised immune system face elevated risk and should weigh that seriously.
