Companion Animal Nutrition: Evidence-Based Feeding for Long-Term Health

Nutrition is foundational to companion animal health and welfare, with evidence-based feeding approaches preventing the chronic diseases that cause suffering and shorten lives.

Key Facts

Diet is the leading preventable contributor to chronic disease in companion animals including obesity, dental disease, and urinary problems
Raw food diets for dogs and cats carry bacterial pathogen risks for both animals and human household members
Grain-free diets for dogs have been associated with dilated cardiomyopathy in non-predisposed breeds
Homemade diets without veterinary nutritionist formulation are commonly deficient in essential nutrients
Life-stage appropriate nutrition — puppy, adult, senior formulas — addresses the changing needs of animals across their lifespan
Water intake is as important as food quality — wet food or supplemental water helps maintain urinary tract health, especially in cats

Welfare Considerations

Companion animal nutrition is an area where well-intentioned owner decisions frequently cause harm through misinformation and wellness trends that lack scientific evidence. Raw diets, grain-free formulations, and homemade meals all carry specific risks that are insufficiently communicated in pet food marketing. The welfare consequences of poor nutrition are long-term — obesity that develops slowly, dental disease that progresses quietly, nutritional deficiencies that impair development or organ function over years. Evidence-based nutrition from veterinary-formulated commercial foods or veterinarian-guided homemade approaches prevents these welfare costs more reliably than trends-based feeding decisions.

What You Can Do

Consult your veterinarian about appropriate diet choices for your specific animal's age, weight, and health status
Choose foods with AAFCO nutritional adequacy statements rather than relying on marketing claims
Be skeptical of pet food wellness trends — consult veterinary nutritionists before adopting alternative diets
Monitor weight regularly and adjust portions to prevent obesity through accurate body condition assessment
Ensure adequate water intake for all companion animals, particularly cats who are prone to urinary problems
