5 ingredients in this list are ones we hold sourced evidence on , and none of them is contested in the veterinary literature.
- Fish oil (EPA + DHA omega-3) · ingredient 11Well supportedMarine-source omega-3 fatty acids (EPA and DHA) from fish oil. A randomized, double-blinded controlled trial (Roush 2010) found improved weight-bearing in dogs with osteoarthritis, and a 2022 meta-analysis identified clear clinical analgesic efficacy for omega-3-enriched diets and supplements.
- Brewers Rice · ingredient 5NeutralAn AAFCO-defined ingredient consisting of the small, broken fragments of rice kernels separated during milling. It is a digestible carbohydrate and energy source nutritionally similar to other rice; the 'brewers' name reflects how the fragments are sourced, not lower nutritional quality.
- Wheat Gluten · ingredient 6NeutralThe concentrated protein fraction of wheat, used as a plant protein and binder; it is highly digestible in dogs (about 88% crude-protein digestibility in one feeding study). The 2007 pet-food deaths linked to wheat gluten were caused by criminal melamine adulteration of imported product to fake protein readings, a contamination event rather than a property of wheat gluten itself.
- Powdered Cellulose · ingredient 10NeutralPurified plant cell-wall fiber (typically from wood pulp) used as an insoluble-fiber source, bulking agent, and anti-caking aid, often in weight-management diets. It is not absorbed and is poorly fermentable, so it firms stool and dilutes calories but yields little of the short-chain fatty acids that more fermentable fibers produce; EFSA's 2018 re-evaluation found no safety concern and no need for a numerical ADI.
- Taurine (supplemental) · ingredient 17NeutralA sulfur amino acid that dogs can normally synthesize from methionine and cysteine, so it is not classically essential for them. However, some breeds (e.g., golden retrievers) and some diets are linked to low taurine status and dilated cardiomyopathy: an observational study (Ontiveros 2020) associated non-traditional, largely grain-free diets with taurine deficiency and DCM-consistent echocardiographic changes in golden retrievers, though causation and mechanism remain under investigation.
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/operates its own plants; Mars opened a new $450M Royal Canin factory in Lewisburg, Ohio in 2025 (confirmed via mars.com press release).

source →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.
