Which dog food brands meet WSAVA guidelines?

“of the 94 diplomates in the American College of Veterinary Nutrition, Hill's employs four, along with two veterinarians who are residency-trained in clinical nutrition.”

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').

“Additionally, all finished products are physically inspected and tested for key nutrients prior to release to help ensure your pet gets a consistent product bag to bag.”

covers: finished-product nutrient analysis (page also says each ingredient is examined and final safety checks run daily on every product; no Salmonella/batch detail on this page).

“An expansive research and development team. Ranging from veterinarians, doctorate-level animal nutritionists, and food safety and quality experts.”

Blue Buffalo's professional site states doctorate-level animal nutritionists on staff. Gaylord, DVM, DACVIM (Nutrition) — a board-certified veterinary nutritionist — and Matt Panasevich, PhD, work at Blue Buffalo.

“All products undergo rigorous testing, including but not limited to, microbiology, nutrient analyses, shelf life, stool quality, urine pH, palatability, digestibility and product efficacy.”

“Formulations are developed by a team of board-certified veterinary nutritionists, Ph. D. nutritionists, and Royal Canin associates with a Masters degree in small animal nutrition.”

Official Royal Canin US page explicitly states board-certified veterinary nutritionists and PhD nutritionists on staff.

“A network of state-of-the-art laboratories across the world conduct detailed analyses on all ingredients and finished products from our manufacturing sites.”

“The vast majority are validated and compliant with AFFCO and FEDIAF nutrient profiles and/or feeding trials, where these are the most relevant nutritional regulators.”

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.

“PEDIGREE dog food employs multiple associates with expertise in nutrition. These include PhD nutritionists and/or veterinarians that ensure proper nutrition compliance of our products to meet Mars Nutritional Standards.”

No feeding-trial AAFCO statement found on the 70 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.
