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.

AAFCO substantiation
Substantiated by AAFCO feeding trials
Hill's Science Diet substantiates nutritional adequacy by feeding the finished food to dogs under AAFCO protocols. This is the stronger of the two routes, because it tests the food as made rather than the recipe on paper.
