Acana vs Hill's Science Diet

Acana (Champion Petfoods' more affordable line; same WSAVA gaps as Orijen) and Hill's Science Diet (veterinarian-recommended premium kibble with the deepest prescription-diet portfolio on the market) compared head-to-head on WSAVA manufacturer-quality criteria, AAFCO substantiation, monthly cost, and which dog each is best for in 2026. Hill's Science Diet meets 5 of 5 WSAVA criteria. Hill's Science Diet is roughly 26% less than Acana.

The verdict

Hill's Science Diet meets all 5 WSAVA criteria with feeding-trial substantiation from an owned research facility; Acana, Champion Petfoods' more affordable line, meets only 2 of 5, uses formulation-only substantiation, and is named in the FDA DCM investigation. Acana's appeal is regional-ingredient recipes and owned manufacturing at a lower price than its sister brand Orijen, landing around $70-120/month versus Hill's $55-85.

Choose Hill's Science Diet for a clinical track record, feeding-trial proof, and a clean path into prescription diets. Choose Acana only for a healthy dog with no cardiac risk factors whose owner values Champion's ingredient philosophy and accepts the WSAVA and DCM trade-offs. If full compliance is your bar, Hill's clearly wins.
