Composition — dry-matter basis

why dry matter
Moisture hides the real recipe: kibble is ~10% water, canned food ~78%. Removing water puts every food on one scale, so these are the only nutrition numbers that can be compared across foods. As-fed label values shown small.
Protein 26.7%label: 24% min lower than 77% of dry foods
Fat 11.1%label: 10% min lower than 93% of dry foods
Fiber 8.7%label: 7.8% max higher than 95% of dry foods
Est. carbohydrates ash not disclosed → 8% assumed, so this is an estimate ≈44.7%computed anchor available once more brands disclose ash
Calcium / Phosphorus extended guarantees: none verified yet Not yet verifiedcalcium/phosphorus no ratio to anchor

Standards & ingredients

AAFCO statement
what this means
Two kinds of AAFCO claims exist. Most foods are only "formulated to meet" nutrient profiles — a paper calculation. A smaller set carry the stronger claim: fed to real dogs in AAFCO-procedure trials ("Animal feeding tests using AAFCO procedures substantiate…").
 Formulated to meet · maintenance
First five ingredients (by pre-cooking weight)Corn · chicken by-product meal · brewers rice · corn gluten meal · wheat gluten
Named animal protein first; named meals onlyNo
Legumes in first 10 (FDA DCM inquiry)1 (pea fiber)
BHA / BHT preservativesNone on label
Carrageenan (thickener)None
Ethoxyquin
why unknown
When a fish-meal supplier adds ethoxyquin, U.S. rules don't require it on the finished label — so no label can prove its absence for recipes containing fish meal. We report this as a gap rather than guessing.
 None — no fish meal in this recipe

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 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).

Employs a qualified nutritionist Yes — sourced

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.)

AAFCO feeding trials Undisclosed

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.

Peer-reviewed research Yes — sourced

199 PubMed-indexed papers carry "Royal Canin" in an author affiliation (animal/pet-domain filtered) — a reproducible floor, not a total.
