Kirkland Signature
Super Premium Adult Chicken Rice & Vegetable
An unusually strong ingredient panel for the price, with chicken and chicken meal leading the list. The main tradeoff is that availability is tied to Costco membership.

Diamond Naturals
All Life Stages Chicken & Rice Formula
A value-priced all-life-stages kibble led by named chicken and chicken meal with whole grains and salmon oil for DHA. The price per calorie is among the lowest in the catalog; Diamond's manufacturing history (2005 and 2012 recalls) is the main reason Brand Trust isn't higher.

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.
