Acana vs Iams

Acana (Champion Petfoods' more affordable line; same WSAVA gaps as Orijen) and Iams (mass-market-priced kibble from a maker that meets 4 of WSAVA's 5 questions, for budget-conscious owners) compared head-to-head on WSAVA manufacturer-quality criteria, AAFCO substantiation, monthly cost, and which dog each is best for in 2026. Iams meets 4 of 5 WSAVA criteria. Iams is roughly 63% less than Acana.

The verdict

Iams meets 4 of 5 WSAVA criteria, with a "formulated to meet" AAFCO label instead of feeding trials, at a mass-market $25-45/month. Acana, Champion Petfoods' more affordable line, meets only 2 of 5, uses formulation-only substantiation, and is named in the FDA DCM investigation, at $70-120, offering regional-ingredient recipes and owned manufacturing.

Choose Iams for a healthy adult dog on a tight budget when a maker meeting 4 of WSAVA's 5 questions is enough. It is both cheaper and stronger on WSAVA answers. 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. On evidence and price, Iams is the stronger choice.
