The maker
Who makes this — and how they back it up
The four questions the WSAVA nutrition guidelines tell you to ask a pet-food company. Every answer is sourced or marked as an undisclosed gap — never guessed. This is the "is it made competently?" axis that star-rating sites skip.
Owns/operates its own plants; Mars opened a new $450M Royal Canin factory in Lewisburg, Ohio in 2025 (confirmed via mars.com press release).
source →Official Royal Canin US page explicitly states board-certified veterinary nutritionists and PhD nutritionists on staff. (Search also surfaced named example Dr. Adrienne Bautista, DVM/PhD, Scientific Affairs Manager at Royal Canin USA, though that name was not from a fetched page.)
source →No feeding-trial AAFCO statement found on the 241 labels we’ve verified for this brand, and no company-wide claim was found either. Most pet foods are only "formulated to meet" AAFCO profiles (a paper calculation) rather than fed to real animals in trials — this is common, not necessarily a red flag.
199 PubMed-indexed papers carry "Royal Canin" in an author affiliation (animal/pet-domain filtered) — a reproducible floor, not a total.
