Purina Pro Plan vs Taste of the Wild

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 Taste of the Wild (grain-inclusive and grain-free kibble at mid-tier pricing; 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. Taste of the Wild is roughly 9% less than Purina Pro Plan.

The verdict

Purina Pro Plan meets all 5 WSAVA criteria with AAFCO feeding-trial substantiation; Taste of the Wild meets just 2 of 5, employs no board-certified veterinary nutritionist, uses formulation-only substantiation, and has grain-free lines named in the FDA DCM investigation plus a 2012 Salmonella recall history. Its appeal is novel-protein recipes (bison, salmon, venison) at $40-65/month versus Pro Plan's $40-75.

Choose Purina Pro Plan for full WSAVA-compliant quality and feeding-trial proof at a similar price point. Choose Taste of the Wild only for a healthy dog with no cardiac risk factors whose owner is specifically drawn to novel proteins. Given comparable pricing, Pro Plan's evidence advantage makes it the safer default.
