The maker

Who makes this — and how they back it up

The five 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 its manufacturing Owns its plants

Owns/operates its own plants; Mars opened a new $450M Royal Canin factory in Lewisburg, Ohio in 2025 (confirmed via mars.com press release).

AAFCO feeding trials Not stated

Ambiguous: Royal Canin's answer to WSAVA's feeding-trial question says 'nutrient profiles and/or feeding trials' and does not say which retail foods had AAFCO feeding trials. every one says 'formulated to meet the nutritional levels established by the AAFCO Dog Food Nutrient Profiles' and none carries an 'animal feeding tests' statement.
