Iams
Leads on PetScored rating, Brand Trust, Ingredient Clarity
Buy on AmazonOur read
Two Mars-owned recipes, and the cheaper line edges it: in our view Iams takes the clearer ingredient panel and a lower sensitivity-risk profile, while Eukanuba's only win is value on cost per 1,000 kcal. They are level on nutrition fit and brand trust.
This verdict is our opinion under the PetScored rubric, not veterinary advice. The exact sub-scores are in the table below; each food’s source confidence and limitations stay on its own scorecard.
Eukanuba
Mass-premium kibble with named chicken sources and disclosed grain inclusions. Common-trigger density is substantial - not for dogs avoiding poultry, corn, wheat, or fish. Adult-maintenance AAFCO.
Iams
Widely available adult maintenance kibble with official Iams package-art support for ingredients, guaranteed analysis, and calorie content. Main watch-outs are chicken, corn, egg, natural flavor, caramel color, and a Brand Trust record that remains partial.
Comparison scores use the same reconstructed score-event math as the product pages. Source confidence, unresolved gaps, recall context, and warning-letter limitations remain attached to each individual scorecard.
