Few topics in pet care divide opinion as sharply as raw feeding. Proponents describe transformative results—glossy coats, clean teeth, boundless energy. Opponents point to documented cases of salmonella, E. coli, and nutritional deficiencies. This guide presents what the evidence actually shows, what veterinarians actually say, and what you need to know to make an informed decision—not a decision based on Instagram testimonials or fear-based marketing from either side.
Raw feeding exists on a spectrum. The two main models are the Prey Model Raw (PMR) diet, which attempts to replicate whole prey animals (80% muscle meat, 10% bone, 10% organs), and the BARF (Biologically Appropriate Raw Food) diet, which includes fruits, vegetables, and supplements alongside raw meat, bones, and organs. Commercial raw diets—frozen or freeze-dried patties formulated to meet AAFCO standards—represent a middle ground between homemade and traditional kibble.
| Claimed Benefit | Strength of Evidence | What We Actually Know |
|---|---|---|
| Shinier coat, healthier skin | Moderate | Higher fat content and omega-3 fatty acids in raw diets likely explain this. You can achieve the same effect by supplementing a commercial diet with fish oil. Not unique to raw feeding. |
| Cleaner teeth, less tartar | Moderate | Chewing raw meaty bones does mechanically clean teeth. However, the risk of dental fractures from bones is real. Veterinary dentists see a steady stream of slab fractures from bone-chewing. Dental chews and brushing provide the same benefit with less risk. |
| Smaller, firmer stools | Strong | This is well-documented and makes biological sense: raw diets contain less indigestible plant material than kibble. Less filler = less waste. This benefit is real and measurable. |
| Fewer allergies, less itching | Weak to Moderate | Some dogs improve on raw diets, but the mechanism is unclear. It may simply reflect elimination of a specific protein they were allergic to in their previous food, not a unique property of raw feeding. An elimination diet with hydrolyzed protein achieves the same diagnostic goal with less risk. |
| Increased energy, "vitality" | Weak | Subjective. Owners switching from low-quality kibble to any higher-quality diet—raw or not—report similar improvements. No controlled studies demonstrate raw-specific energy benefits. |
| Longer lifespan | None | No long-term controlled studies exist comparing lifespan outcomes between raw-fed and kibble-fed dogs. Any lifespan claims are anecdotal. |
| Risk | Severity | Evidence | Who Is Most Vulnerable |
|---|---|---|---|
| Bacterial contamination (Salmonella, E. coli, Listeria, Campylobacter) | High | Multiple studies (FDA, JAVMA) have found pathogenic bacteria in 30–50% of commercial raw dog food samples tested. This is not a hypothetical risk. | The dog itself can become ill. More importantly, the dog sheds bacteria in feces and saliva, infecting humans in the household. Children, elderly, pregnant women, and immunocompromised individuals are at highest risk. |
| Nutritional imbalance (homemade raw) | High | Studies analyzing homemade raw diet recipes—including those published in books and online—consistently find deficiencies in calcium, phosphorus, vitamin D, vitamin E, and other essential nutrients. Long-term feeding of unbalanced homemade raw causes metabolic bone disease in puppies and nutritional deficiencies in adults. | Growing puppies are at extreme risk. Improper calcium-to-phosphorus ratios during growth cause irreversible skeletal deformities. |
| Bone-related injuries | Moderate | Dental fractures, esophageal obstructions, gastrointestinal perforations from bone fragments. Emergency veterinary hospitals see these cases regularly. | Aggressive chewers, small dogs given bones too large or dense for their size. |
| Hyperthyroidism (raw feeding) | Low but documented | Raw diets containing thyroid gland tissue (from neck/head meat) can cause dietary hyperthyroidism. Reversible when discontinued, but concerning. | Any dog on raw diet containing gullet/neck meat. |
The American Veterinary Medical Association (AVMA) policy states: “The AVMA discourages the feeding to cats and dogs of any animal-source protein that has not first been subjected to a process to eliminate pathogens.” The American Animal Hospital Association (AAHA), American College of Veterinary Nutrition (ACVN), and FDA Center for Veterinary Medicine all recommend against raw feeding due to pathogen risk to both pets and humans. This is not one organization being cautious—it’s a near-universal consensus among veterinary professional bodies.
If you’ve weighed the evidence and still want to feed raw, here’s how to minimize risk:
Use commercial raw diets, not homemade. Formulated commercial raw from companies like Stella & Chewy’s or Primal Pet Foods has been formulated to meet AAFCO standards and undergoes some pathogen testing. This doesn’t eliminate risk but reduces the nutritional deficiency risk dramatically compared to DIY. If you do homemade, work directly with a board-certified veterinary nutritionist (DACVN) to formulate the diet—do not rely on internet recipes.
Practice strict hygiene. Treat raw dog food like raw chicken in your kitchen. Dedicated preparation surfaces, immediate cleanup with disinfectant, hand washing after any contact, and keeping dogs from licking faces immediately after eating. Do not feed raw in households with immunocompromised individuals.
Regular veterinary monitoring. Blood work every 6–12 months to catch nutritional deficiencies before they cause clinical disease. Fecal testing to monitor for parasite and bacterial shedding. Be honest with your veterinarian about what you’re feeding—they need to know to interpret lab results correctly.
