The evidence

The Verified Label

Every food on this site gets this exact panel — same fields, same order, sourced from the official label — so brands finally become comparable. Corpus dot-anchors currently cover dry food only — this is a wet food, so anchors are omitted below rather than compared across forms.

why dry matter
Kibble is ~10% water, canned food ~78%, so as-fed numbers are on two different scales. As-fed values shown small. How the conversion works →

The source material

The full ingredient list

Every flag above is computed from this list. Why order is by pre-cooking weight, and how splitting bends it →

Water sufficient for processing, pork by-products, pork liver, chicken liver, chicken, wheat flour, powdered cellulose, dried plain beet pulp, calcium carbonate, carrageenan, carob bean gum, natural flavors, potassium chloride, sodium silico aluminate, pork plasma, taurine, guar gum, sodium tripolyphosphate, salt, vitamins [L-ascorbyl-2-polyphosphate (source of vitamin C), DL-alpha tocopherol acetate (source of vitamin E), thiamine mononitrate (vitamin B1), niacin supplement, biotin, D-calcium pantothenate, riboflavin supplement, pyridoxine hydrochloride (vitamin B6), vitamin B12 supplement, folic acid, vitamin D3 supplement], citric acid, sodium carbonate, L-carnitine, magnesium oxide, marigold extract (Tagetes erecta L.), trace minerals [zinc oxide, ferrous sulfate, zinc proteinate, copper sulfate, manganous oxide, sodium selenite, calcium iodate]

5 ingredients in this list are ones we hold sourced evidence on , and 1 of them is genuinely contested rather than merely unpopular online.

  • Carrageenan · ingredient 10Worth knowingA seaweed-derived (Chondrus crispus) thickener and gelling agent used mainly in some wet and canned dog foods. Low-molecular-weight 'degraded' carrageenan (poligeenan) is inflammatory in lab-animal studies and is not permitted as a food additive, but food-grade undegraded carrageenan (E 407) is authorized by regulators; EFSA's 2018 re-evaluation kept only a temporary group ADI of 75 mg/kg body weight per day pending better data, and its specific effect in dogs is unresolved.
  • Beet Pulp · ingredient 8Well supportedThe fibrous material left after sugar is extracted from sugar beets, included as a moderately fermentable fiber source (commonly around 5 to 7.5% of the diet). Controlled feeding studies show it supports firm, good-quality stools and short-chain fatty acid production without impairing overall nutrient digestibility, so the 'cheap filler' characterization is not supported by the evidence.
  • Powdered Cellulose · ingredient 7NeutralPurified 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 16NeutralA 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.
  • Guar Gum · ingredient 17NeutralA soluble, viscous fiber from the guar bean used in small amounts to thicken and stabilize foods, mostly wet formulas. At higher dietary inclusion it can lower the digestibility of dry matter and protein in dogs, but it also produces metabolic effects such as reduced post-meal insulin and cholesterol; at the low levels used as a thickener these effects are minor.

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.
