Dog Food Safety and Welfare | Animal Welfare Hub

How food safety issues in commercial pet food affect dog welfare, and how owners can make informed choices.

Key Facts

The FDA receives thousands of pet food adverse event reports annually covering illness and death
Pet food contamination events have included melamine (2007, thousands of deaths), pentobarbital, and Salmonella
The 2019 FDA investigation into a potential link between grain-free diets and dilated cardiomyopathy (DCM) remains ongoing
AAFCO regulates minimum nutritional standards but does not require pre-market testing of commercial pet foods
Raw meat diets carry Salmonella and other pathogen risks to both pets and their human families
Home-cooked diets are frequently nutritionally deficient unless formulated by a board-certified veterinary nutritionist
Manufacturers are required to recall products found to be unsafe — subscribing to recall alerts is an important safety practice

Welfare Considerations

Pet food safety is a welfare issue because contaminated or nutritionally inadequate food causes disease, organ damage, and death in companion animals who depend on their owners for nutritional provision. The regulatory framework for pet food prioritizes post-market surveillance over pre-market testing, meaning problems are often discovered after animals have already been affected. Informed owners who choose foods with strong safety records, track recall alerts, and consult veterinary nutritionists for special diets significantly reduce their companion animals risk from food-related welfare harms. This is not an area where common sense and price premium are reliable guides — careful research and veterinary guidance provide better safety protection.

What You Can Do

Subscribe to FDA MedWatch or equivalent pet food safety alerts in your country
Consult your veterinarian before making significant changes to your dog diet, particularly to raw or grain-free diets
If feeding home-cooked diets, have them formulated by a board-certified veterinary nutritionist
Choose foods with strong safety records and report adverse events to your veterinarian and the FDA
Be appropriately skeptical of marketing claims about premium pet foods — price does not reliably indicate quality or safety
