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 13.3%label: 12% min lower than 82% of dry foods
Fiber 4.4%label: 4% max lower than 69% of dry foods
Est. carbohydrates ash not disclosed → 8% assumed, so this is an estimate ≈48.9%computed anchor available once more brands disclose ash
Calcium / Phosphorus extended guarantees: Ca 1% · P 0.8% · Ω-3 0.3% 1.25 : 1ratio, as fed within the AAFCO adult range (1:1 – 2:1)

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)Chicken by-product meal (a source of glucosamine) · wheat flour · whole grain ground corn · rice bran · grain sorghum
Named animal protein first; named meals onlyYes
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
