Is Hill's Science Diet WSAVA-Approved?
WSAVA does not approve, certify, or endorse any dog food brand — no such list exists. What "WSAVA-approved" actually refers to is whether a manufacturer satisfies the five questions the WSAVA Global Nutrition Committee tells owners to ask. Hill's Science Diet meets all 5, which puts it in the small group of brands that satisfy the full rubric. It substantiates its diets through AAFCO feeding trials, and typically costs $55–$85 per month for a 50 lb adult dog.
