Our read

A dead heat on composite that splits cleanly by what you pay for: Hill's leads on nutrition fit and a much stronger brand-trust record, while Diamond Naturals answers with a lower sensitivity-risk profile and far better value, since Hill's price per 1,000 kcal sits near the bottom of the range we score. Ingredient clarity is tied. In our view, the value-minded choice is Diamond.

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.

Hill's Science Diet

Adult Chicken & Barley Recipe Dog Food

Source-backed adult maintenance dry food with AAFCO feeding-test language and clear calorie data. Watch-outs are chicken and wheat sensitivity exposure plus a historical Hill’s canned-dog-food recall/warning-letter record that remains disclosed as brand-level regulatory history.

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.
