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 27.8%label: 25% min lower than 68% of dry foods
Fat 12.2%label: 11% min lower than 88% of dry foods
Fiber 3.3%label: 3% max lower than 98% of dry foods
Est. carbohydrates ash not disclosed → 8% assumed, so this is an estimate ≈47.8%computed anchor available once more brands disclose ash
Calcium / Phosphorus extended guarantees: Ca 1.1% · P 0.8% · Ω-3 0.3% 1.38 : 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 · chicken meal · whole grain brown rice · cracked pearled barley · white rice
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

The maker

Who makes this — and how they back it up

The four 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

Diamond Pet Foods owns and operates its own U.S. plants (Meta MO; Lathrop CA 1999; Gaston SC 2003; Ripon CA 2012; Dumas AR 2016; Frontenac KS 2021), where Diamond Naturals is produced.

Employs a qualified nutritionist Undisclosed

The source refers to disciplines/experts (veterinary medicine, companion animal nutrition) but does NOT name any specific board-certified veterinary nutritionist (ACVN/ECVCN Diplomate) or PhD nutritionist on staff. Per rules, null.

source →
AAFCO feeding trials Undisclosed

No feeding-trial AAFCO statement found on the 31 labels we’ve verified for this brand, and no company-wide claim was found either. Most pet foods are only "formulated to meet" AAFCO profiles (a paper calculation) rather than fed to real animals in trials — this is common, not necessarily a red flag.

Peer-reviewed research None found

A reproducible PubMed search (author-affiliation field, animal/pet-domain filtered) returns zero indexed papers for this brand name. Not proof no research exists — only that none is PubMed-indexed under this exact name.
