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 35.6%label: 32% min higher than 84% of dry foods
Fat 20%label: 18% min higher than 90% of dry foods
Fiber 5.6%label: 5% max typical — the median dry food is 5.4%
Est. carbohydrates ash not disclosed → 8% assumed, so this is an estimate ≈30%computed anchor available once more brands disclose ash
Calcium / Phosphorus extended guarantees: Ca 1.2% · P 0.8% · Ω-3 0.4% 1.50 : 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…").

First five ingredients (by pre-cooking weight)Chicken · Chicken By-Product Meal (source of Glucosamine and Chondroitin Sulfate) · Ground Whole Grain Corn · Ground Whole Grain Sorghum · Chicken Meal
Named animal protein first; named meals onlyYes
Legumes in first 10 (FDA DCM inquiry)None

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

Nutritional twins

Cheaper close matches

Verified foods with a closely matching label at a meaningfully lower cost per 1,000 kcal.

Diamond Performance

Label-composition matches only: same species, form, and growth stage; same primary protein where both are known; grain-free preserved; protein within 4 points and fat within 4 points, and estimated carbs within 8 points, on a dry-matter basis. Not a medical or quality recommendation.

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

Iams is produced at Mars Petcare's owned/operated Mattoon, Illinois plant.

Employs a qualified nutritionist Undisclosed

Iams homepage and FAQ (both fetched) did not state any nutritionist credentials. Iams is part of the same Mars Pet Nutrition / Waltham system as Pedigree (which DOES employ PhD nutritionists), but no Iams-specific fetched source explicitly names a board-certified vet nutritionist or PhD nutritionist on staff, so set to null per the no-fabrication rule.

source →
AAFCO feeding trials Undisclosed

No feeding-trial AAFCO statement found on the 101 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 Yes — sourced

658 PubMed-indexed papers carry "Waltham Petcare Science Institute (Mars)" in an author affiliation (animal/pet-domain filtered) — a reproducible floor, not a total.
