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 15%label: 13.5% min lower than 69% 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 ≈43.9%computed anchor available once more brands disclose ash
Calcium / Phosphorus extended guarantees: Ca 0.75% · Ω-3 0.3% Not yet verifiedcalcium/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…").
 Not yet verified from label
First five ingredients (by pre-cooking weight)Beef · Chicken By-Product Meal · Brewers Rice · Ground Whole Grain Corn · Ground Whole Grain Sorghum
Named animal protein first; named meals onlyYes
Legumes in first 10 (FDA DCM inquiry)1 (soybean meal)
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

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.

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.
