THE FACTS, ONE SENTENCE — · 126 Hill's Science Diet foods in our corpus
The scorecard
WSAVA-aligned criteria
The World Small Animal Veterinary Association's nutrition guidelines suggest four questions to ask any pet food maker before you buy. Most "best dog food" sites skip straight to ingredient vibes and star ratings — we publish the actual answers instead, each sourced, or marked honestly undisclosed when we can't confirm it.
4 of 4 criteria confirmed yes · 0 confirmed no · 0 undisclosed. Undisclosed is common, especially for smaller brands — it means we couldn't confirm an answer from a public source, not that the answer is unfavorable.
Hill's explicitly employs four ACVN Diplomates (board-certified veterinary nutritionists) plus PhD nutritionists per same page ('Our staff of PhD nutritionists, food scientists, flavorists and veterinarians').

FDA recall history
Joined from the FDA's own Animal & Veterinary recall feed (2019–present) plus curated pre-2019 records — the same live-checked feed as our full recall database, filtered to Hill's Science Diet.
