The scorecard
WSAVA-aligned criteria
The World Small Animal Veterinary Association's nutrition guidelines suggest four questions to ask any pet food maker before you buy. Most "best dog food" sites skip straight to ingredient vibes and star ratings — we publish the actual answers instead, each sourced, or marked honestly undisclosed when we can't confirm it.
2 of 4 criteria confirmed yes · 0 confirmed no · 2 undisclosed. Undisclosed is common, especially for smaller brands — it means we couldn't confirm an answer from a public source, not that the answer is unfavorable.
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
Iams is produced at Mars Petcare's owned/operated Mattoon, Illinois plant.

No feeding-trial AAFCO statement found on the 8 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.
658 PubMed-indexed papers carry "Waltham Petcare Science Institute (Mars)" in an author affiliation (animal/pet-domain filtered) — a reproducible floor, not a total.

The safety record
FDA recall history
Joined from the FDA's own Animal & Veterinary recall feed (2019–present) plus curated pre-2019 records — the same live-checked feed as our full recall database, filtered to Iams.
Join of data/recalls.json (FDA Animal & Veterinary recall feed, 2019-present) + data/recalls_historical.json. This is NOT a complete lifetime recall history; recalls predating 2019 (or absent from the FDA datatable) are not represented unless curated in recalls_historical.json.
