Dog Nutrition Science: Evidence-Based Feeding for Welfare

Canine nutrition science provides clear guidance on optimal dog feeding — but marketing and misinformation make evidence-based choices challenging for many owners.

Key Facts

The AAFCO and FEDIAF nutritional standards for dogs are based on decades of canine nutrition research
Grain-free diets in dogs have been associated with dilated cardiomyopathy (DCM) in FDA investigations
Raw meat diets carry significant risks of bacterial contamination (Salmonella, E. coli) for dogs and human household members
Life stage nutrition matters — puppy, adult, and senior diets are formulated for different physiological needs
Caloric density of diets should be matched to individual dog energy expenditure to prevent obesity
WSAVA (World Small Animal Veterinary Association) provides evidence-based dog food selection guidance

Welfare Considerations

Dog nutrition is an area where marketing significantly outpaces evidence, creating welfare risks from nutritionally unbalanced trendy diets. The AAFCO/FEDIAF nutritional standards — developed from canine nutrition science — provide a reliable foundation; diets meeting these standards from established manufacturers with veterinary nutrition expertise are the safest choice for most dogs. Grain-free, raw, and boutique diets may be appropriate in specific circumstances but require veterinary guidance and ongoing monitoring. Evidence-based feeding — appropriate caloric intake, life-stage nutrition, and avoidance of nutritionally unverified trends — is a foundational welfare responsibility.

What You Can Do

Choose dog foods that meet AAFCO or FEDIAF nutritional standards and are made by companies with veterinary nutrition expertise
Consult your veterinarian before switching to raw, grain-free, or novel protein diets
Follow WSAVA food selection guidelines when evaluating dog food brands and formulations
Monitor body condition score regularly and adjust portions to maintain lean, healthy body weight
