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 24.4%label: 22% min lower than 90% of dry foods
Fat 20%label: 18% min higher than 90% of dry foods
Fiber 5.2%label: 4.7% max typical — the median dry food is 5.4%
Est. carbohydrates ash not disclosed → 8% assumed, so this is an estimate ≈41.4%computed anchor available once more brands disclose ash
Calcium / Phosphorus extended guarantees: Ω-3 0.43% Not disclosedcalcium/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)Ingredient: brewers rice · brown rice · chicken by-product meal · chicken fat · oat groats
Named animal protein first; named meals onlyNo
Legumes in first 10 (FDA DCM inquiry)None
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
