Companion Animal Nutrition and Welfare Outcomes

Nutritional quality is a fundamental welfare dimension for companion animals that affects health outcomes across the entire lifespan.

Key Facts

Dogs and cats have specific nutritional requirements that differ significantly from each other and from humans
Cats are obligate carnivores requiring taurine and arachidonic acid that dogs can synthesize but cats cannot
Grain-free diets in dogs have been associated with dilated cardiomyopathy in some studies
Raw food diets carry bacterial contamination risks for both pets and their human household members
AAFCO nutritional adequacy statements on pet food labels indicate minimum nutrient standard compliance

Welfare Considerations

Companion animal nutrition is a welfare issue that directly determines health outcomes across the entire lifespan. Feeding an inappropriate diet affects immune function, organ health, weight management, and disease susceptibility in ways that accumulate over years. The pet food market is complex, with significant variation in quality, and marketing claims that may not align with nutritional evidence. Veterinary nutritional guidance based on individual animal needs — species, age, health status, and activity level — provides the most reliable foundation for welfare-positive feeding decisions. When in doubt, consulting a board-certified veterinary nutritionist provides the highest level of evidence-based guidance.

What You Can Do

Feed complete and balanced diets bearing AAFCO nutritional adequacy statements appropriate to your pet life stage
Consult your veterinarian about dietary needs for pets with specific health conditions
Be cautious of extreme dietary trends for pets and seek veterinary evidence before adopting them
Consider consultation with a board-certified veterinary nutritionist for pets with complex dietary needs
