Advances in companion animal nutrition science are improving health and welfare outcomes for dogs and cats, but misinformation in the pet food market remains a significant challenge.
Companion animal nutrition decisions are increasingly complicated by commercial marketing that outpaces scientific evidence. Grain-free diets promoted as natural and species-appropriate have been associated with serious cardiac disease in some dog breeds. Raw meat diets promoted for ancestral authenticity carry pathogen risks that affect animal and human health. Meanwhile, the genuine nutrition challenge — caloric excess leading to obesity — receives less attention than trendy dietary philosophies. Evidence-based companion animal nutrition focuses on life stage appropriateness, appropriate caloric density, essential nutrient completeness, and digestibility. Veterinary nutritionist guidance, rather than pet food marketing claims, is the reliable foundation for welfare-positive feeding decisions.
