Raw Dog Food Diet: Benefits, Risks, and How to Do It Safely

What Is a Raw Dog Food Diet?

The most common raw feeding framework is BARF — Biologically Appropriate Raw Food (or Bones and Raw Food), popularized by Australian veterinarian Ian Billinghurst. A BARF diet typically consists of 60–80% raw meaty bones, 10–20% organ meat, and 10–20% fruits and vegetables.

Other raw models include the "prey model" (attempting to replicate whole prey: ~80% muscle meat, 10% raw edible bone, 10% organ) and commercial raw diets (frozen or freeze-dried, typically more nutritionally balanced than home-prepared versions).

For context on how raw fits into the broader nutrition picture, see the complete dog nutrition guide.

Claimed Benefits: What the Evidence Shows

Improved coat quality — frequently reported by raw feeders. Plausible mechanism: higher fat content (particularly omega-3s) from fish and organs. However, higher omega-3 content can be achieved with supplements or fish-based kibble without raw feeding.

Better dental health — raw meaty bones provide mechanical abrasion that reduces tartar buildup. This benefit has reasonable support. However, cooked or recreational raw bones also carry fracture and perforation risks; the dental benefit of raw diets should be balanced against safety concerns.

Improved digestion and firmer stools — frequently reported. Lower fiber and higher protein diets generally do produce firmer stools. Whether this represents genuinely better digestive health or simply less fermentation is debated.

Increased energy and vitality — owner-reported, highly subjective, and not supported by controlled studies. Many improvements reported when switching to raw may reflect better food quality (from any high-protein diet) rather than raw feeding specifically.

Real Risks That Require Serious Consideration

Bacterial contamination. Multiple studies have found raw pet foods contaminated with Salmonella, Listeria monocytogenes, and E. coli — at rates significantly higher than commercial kibble. The risk isn't just to the dog: humans handling raw food and surfaces/bowls the dog contacts are also exposed. This is particularly serious for households with young children, elderly people, pregnant women, or immunocompromised individuals.

A 2018 study published in Vet Record found Salmonella in 54% of raw pet food samples and Listeria in 15%. The FDA has issued multiple recalls of commercially prepared raw pet foods for bacterial contamination.

Nutritional imbalance. Home-prepared raw diets are consistently found to be nutritionally incomplete. A 2019 study in the Journal of Animal Physiology found that 60% of raw diet recipes available online had nutritional imbalances — most commonly calcium deficiency. Calcium deficiency in growing dogs causes severe bone disease. Over-supplementation with calcium causes equally severe problems. Without veterinary nutritionist oversight, getting the balance right is very difficult.

Bone hazards. Raw bones can still fracture teeth, cause intestinal perforation, and create obstruction. Risks are lower than with cooked bones but not zero. Small, weight-bearing bones (leg bones of large animals) are most dangerous.

Parasites. Raw meat can contain Toxoplasma, Neospora, and tapeworm cysts. Freezing at -4°F (-20°C) for at least 72 hours kills most (but not all) parasites. Many commercial raw preparations include freeze treatment.

What Veterinary Organizations Say

The American Veterinary Medical Association (AVMA), the American Animal Hospital Association (AAHA), and the World Small Animal Veterinary Association (WSAVA) all discourage raw feeding, citing food safety risks and nutritional imbalance concerns.

Many individual veterinarians are more nuanced — acknowledging that well-formulated, commercially prepared raw diets may be safer than home-prepared versions, and that some dogs (particularly those with specific food sensitivities) may benefit from raw or minimally processed food options.

How to Feed Raw More Safely

If you choose to feed raw despite the risks, these steps reduce but don't eliminate hazard:

Use commercially prepared frozen raw rather than home-prepared — commercial products undergo batch testing and are more nutritionally complete. Look for brands that test for pathogens and meet AAFCO standards.

Practice strict food safety: Thaw in the refrigerator (not on the counter). Wash hands, bowls, and surfaces with hot soapy water after every meal. Use stainless steel or glass bowls (easier to sanitize). Do not allow dogs to lick faces after eating raw.

Have a veterinary nutritionist review your diet if home-preparing — use the BalanceIT tool or consult a board-certified veterinary nutritionist. Do not rely on online recipes without professional review.

Parasites: Freeze all meat at -4°F (-20°C) for a minimum of 72 hours before feeding. This kills most (not all) parasites.

Who Should Not Feed Raw

Households with immunocompromised individuals (HIV/AIDS, chemotherapy patients, organ transplant recipients), very young children (under 5), pregnant women, or elderly individuals face elevated risk from household exposure to raw pet food pathogens. The CDC actively advises against raw pet food in these households.

Dogs with compromised immune systems (on immunosuppressive medication, cancer treatment, or with certain chronic diseases) also face elevated risk from raw feeding.

Alternatives That Capture Some Raw Benefits

If the appeal of raw is better coat quality and digestive health, several alternatives deliver similar benefits with less risk: High-quality fresh food delivery (services like The Farmer's Dog, Nom Nom) use gently cooked formulas that are USDA-grade ingredient quality, nutritionally complete, and pathogen-safe. Freeze-dried raw reduces bacterial contamination risk significantly while preserving more nutrient integrity than kibble. High-protein, limited-ingredient kibble with omega-3 supplementation addresses most of the nutritional gaps that motivate raw feeding.
