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 33.3%label: 30% min higher than 75% of dry foods
Fat 11.1%label: 10% min lower than 93% of dry foods
Fiber 18.9%label: 17% max higher than 100% of dry foods
Est. carbohydrates ash not disclosed → 8% assumed, so this is an estimate ≈27.8%computed anchor available once more brands disclose ash
Calcium / Phosphorus extended guarantees: Ca 1% · P 0.7% · Ω-3 0.5% 1.43 : 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…").
 Feeding trials ✓ · maintenance
First five ingredients (by pre-cooking weight)Deboned Chicken · Chicken Meal · Brown Rice · Barley · Powdered Cellulose
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.

Wet ingredients like fresh deboned chicken shrink once cooked — which is why named meals appearing high on the list matter: they keep meaningful animal protein after moisture is removed.
