Purina Pro Plan vs Wellness CORE

Purina Pro Plan (meets all 5 of WSAVA's manufacturer questions, with Sport Performance and Bright Mind lines, at a lower price than Hill's Science Diet or Royal Canin) and Wellness CORE (higher-protein boutique kibble with partial WSAVA compliance) compared head-to-head on WSAVA manufacturer-quality criteria, AAFCO substantiation, monthly cost, and which dog each is best for in 2026. Purina Pro Plan meets 5 of 5 WSAVA criteria. Purina Pro Plan is roughly 23% less than Wellness CORE.

The verdict

Purina Pro Plan meets all 5 WSAVA criteria with AAFCO feeding-trial substantiation; Wellness CORE, a higher-protein boutique kibble, meets only 2 of 5, owns its plants through Wellness Pet Company, but uses formulation-only substantiation and has no full-time board-certified veterinary nutritionist. Some individual FDA complaints name grain-free CORE recipes, though Wellness was not among the brands its June 2019 update named most often. Pricing runs $40-75/month for Pro Plan against $55-95 for Wellness CORE.

Pick Purina Pro Plan for full compliance and feeding-trial proof at a lower price. Pick Wellness CORE only if you specifically want higher protein content and accept partial WSAVA compliance. If your dog has cardiac risk or you want feeding-trial-substantiated food, Pro Plan is both safer and cheaper.
