Americans spend $60 billion on pet food annually — making the United States the world’s largest pet food market by a significant margin. Yet 56% of American dogs and 60% of US cats are overweight or obese, often as a result of US feeding decisions guided by persuasive US pet food marketing rather than US nutritional science. The quality gap between US pet food products is substantial — ranging from commodity US ingredient formulations using low-quality US protein sources to US human-grade fresh US meal programs developed with veterinary nutritionists. These 25 websites help American pet owners make evidence-based feeding decisions in 2026.

💡 Pro Tip: American dog owners can make the most informed US pet food decision by consulting their US veterinarian alongside checking Dog Food Advisor’s ratings and verifying the manufacturer meets WSAVA’s three key US nutritional criteria — employing a board-certified veterinary nutritionist (DACVN), conducting AAFCO feeding trials rather than just US nutrient analysis, and publishing US peer-reviewed nutritional research. US brands meeting all three US WSAVA criteria include Hill’s Science Diet, Royal Canin, Purina Pro Plan, and Eukanuba — a fact that surprises many American dog owners who associate US premium pricing with US superior nutritional quality.
