What does the evidence actually say about raw feeding pets?
The claimed benefits are largely unsupported by controlled evidence, while the risks — particularly microbiological — are well documented. That is the honest summary, and it is more one-sided than the public debate suggests.
What raw feeding means. Uncooked meat, bone and offal, either commercially prepared or home-assembled, sometimes with vegetables.
The claims made for it: shinier coats, better teeth, smaller stools, more energy, fewer allergies, and that it is more "natural".
What the evidence shows:
Smaller, firmer stools are real and simply reflect higher digestibility and lower fibre.
Coat appearance may improve with higher fat content, which is not specific to raw food.
Dental benefit from chewing bone has some plausibility, and is offset by documented risk of fractured teeth, obstruction and perforation.
Health, longevity and allergy claims lack supporting controlled trials. The "ancestral diet" argument is weak, since dogs diverged from wolves thousands of years ago and evolved increased starch-digesting capability in the process.
The documented risks:
Bacterial contamination — salmonella, campylobacter, listeria and E. coli — found repeatedly in commercial raw products in surveys across several countries.
Antimicrobial-resistant bacteria, found in raw pet food, which is a public health concern beyond the individual animal.
Transmission to humans, through the animal shedding organisms and through kitchen contamination. The risk is concentrated in households with children, elderly or immunocompromised people — and some hospitals and care settings exclude raw-fed animals from visiting programmes for exactly this reason.
Nutritional imbalance in home-prepared diets, which analyses find frequently deficient or excessive in calcium, phosphorus and vitamins.
Parasites, where freezing protocols are not followed.
What veterinary bodies say. Most major associations advise against raw feeding, principally on public health grounds.
If you feed raw anyway: use a reputable commercial product formulated as complete, handle it as you would raw chicken for humans, store and defrost separately, wash hands and surfaces, and tell your vet.
