What Is Raw Feeding?

Raw feeding refers to giving dogs and cats unprocessed, uncooked animal-based foods — typically raw muscle meat, organ meat, raw bones, and sometimes eggs, dairy, fruits, or vegetables. It stands in contrast to commercially processed kibble or canned food, which are cooked and formulated to meet established nutritional standards.

Pet owners who choose raw feeding usually follow one of a few approaches. The BARF model (Biologically Appropriate Raw Food, sometimes called Bones and Raw Food) is one of the most common structured frameworks. Others follow a prey-model approach, which more closely mimics the proportions of a whole prey animal. Some pet owners purchase commercially prepared raw diets — sold frozen or freeze-dried — that aim to make the approach more convenient and standardized.

Before going further, it helps to understand some foundational nutrition language. Our pet nutrition terms guide offers plain-language definitions of terms like crude protein, AAFCO standards, and life-stage formulas that will come up throughout any raw feeding conversation.

BARF Diet

Stands for Biologically Appropriate Raw Food (or Bones and Raw Food). A structured raw feeding approach that includes raw meaty bones, muscle meat, organ meat, and sometimes plant matter.

AAFCO Standards

Guidelines set by the Association of American Feed Control Officials that define minimum nutritional requirements for pet foods at different life stages. Foods meeting these standards carry a nutritional adequacy statement on their label.

Pathogen

A microorganism — such as a bacterium, virus, or parasite — capable of causing disease. In raw feeding, pathogens like Salmonella and Listeria are a key safety concern.

Prey-Model Diet

A raw feeding approach that attempts to replicate the proportions of a whole prey animal, typically emphasizing muscle meat, organ meat, and bone without plant-based ingredients.

Nutritional Adequacy Statement

A label claim, based on AAFCO guidelines, indicating that a pet food meets the minimum nutritional requirements for a specified life stage. It does not guarantee that the food is optimal, only that it meets a defined standard.

Veterinary Nutritionist

A veterinarian with advanced, board-certified training in animal nutrition. They are the most qualified professionals to design or evaluate a customized diet plan for an individual pet.

What Proponents Claim — and What Research Shows

Advocates of raw feeding commonly report improvements in coat quality, digestion, energy levels, dental health, and stool volume. These accounts are widespread and genuinely motivate many pet owners to consider raw diets. They deserve respect — but they also deserve scrutiny.

The scientific evidence supporting these claims is, at present, limited. Most studies on raw pet diets are small, short in duration, or lack control groups. Some research has found digestibility advantages for certain raw diet formats, while other studies have identified no meaningful clinical benefit over high-quality commercial diets. The honest summary is that the research base is not yet robust enough to draw firm conclusions either way.

It's also worth noting that many perceived improvements after switching diets — any diet — can reflect the novelty effect or a transition away from a lower-quality food, rather than something specific to rawness itself. Our article on pet nutrition myths explores how anecdote and evidence often diverge in this space.

Evaluating Any Diet Change Objectively

When switching any pet food — raw or otherwise — give it at least 8–12 weeks before drawing conclusions, and keep other variables (treats, supplements, activity level) consistent. Changes you observe may reflect the transition itself rather than the new diet's inherent qualities. Tracking your pet's weight, coat condition, and stool quality in a simple log can help you have a more productive conversation with your vet.

Legitimate Risks to Understand

The risks associated with raw feeding are better documented than the benefits. The most significant is pathogen contamination. Raw meat — even human-grade — can harbor Salmonella, Listeria monocytogenes, E. coli, and other harmful bacteria. Studies examining commercial raw pet food products have consistently detected these pathogens at notable rates.

This is a concern not just for pets, but for the people in the household. Children, elderly individuals, pregnant people, and anyone with a compromised immune system face elevated risk from exposure to contaminated surfaces, bowls, and pet saliva. The U.S. Food and Drug Administration has issued guidance cautioning against raw pet diets specifically because of this cross-contamination risk.

Raw bones, while appealing to proponents for dental benefits, also carry risks: splintering (particularly with cooked bones, but possible with some raw bones too), gastrointestinal obstruction, and dental fractures. Parasite transmission is an additional concern with some raw protein sources, particularly pork and fish if not sourced carefully.

Cross-Contamination Is a Real Household Risk

Raw pet food handling requires the same food-safety discipline as handling raw meat for human consumption — separate cutting boards, thorough handwashing, and sanitizing bowls and surfaces after each feeding. If anyone in your household is immunocompromised, elderly, pregnant, or a young child, discuss the heightened risks with both your veterinarian and a relevant healthcare provider before starting a raw diet.

Nutritional Completeness: The Hardest Part

One of the most consistently documented problems with homemade raw diets is nutritional imbalance. Meeting the complete nutrient profiles established by the Association of American Feed Control Officials (AAFCO) is considerably more complex than assembling a bowl of meat and vegetables.

Research has found that a large proportion of home-prepared raw diets — including those following published recipes — contain deficiencies or excesses in key nutrients: calcium and phosphorus ratios, zinc, vitamin D, iodine, and others. These gaps may not cause immediate visible symptoms but can have cumulative effects on bone health, organ function, and development, particularly in growing animals.

This challenge parallels what owners encounter with other homemade diets. Our companion piece on nutritional gaps in homemade pet diets covers this in detail and is worth reading alongside this overview.

Commercial raw diets that carry an AAFCO nutritional adequacy statement provide more assurance than home-assembled recipes, though they do not eliminate the food-safety concerns described above. If you're evaluating any new food — raw or otherwise — our practical pet food checklist offers a structured way to assess the options.

What Veterinary Guidance Recommends

The American Veterinary Medical Association (AVMA), the American Animal Hospital Association (AAHA), and several veterinary nutrition boards have issued position statements advising caution about raw protein diets for pets. Their concerns center primarily on foodborne illness risks and the difficulty of ensuring nutritional adequacy.

That said, veterinary professionals are not monolithic. Some veterinarians — particularly those with additional training in integrative or holistic medicine — take a more open view, especially when raw feeding is approached thoughtfully and under professional supervision. A board-certified veterinary nutritionist (diplomate of the American College of Veterinary Nutrition) is the most qualified professional to help design or evaluate a raw diet plan for a specific animal.

If you're considering raw feeding, the most responsible starting point is an honest conversation with your veterinarian before making any change. Bring questions about your pet's current health status, any conditions that might increase risk, and what monitoring would look like. Pets with immune system issues, gastrointestinal disease, or those in households with vulnerable humans are generally not considered good candidates for raw feeding.

Whatever you decide about diet, the foundation remains the same: regular veterinary checkups, access to fresh water, and age-appropriate, complete nutrition. Our hub on pet health and wellness is a good broader resource as you think through your pet's overall care.
