Blue Buffalo vs Eukanuba

Blue Buffalo (mid-premium kibble marketed on ingredient quality; partial WSAVA compliance) and Eukanuba (performance-oriented kibble for active and working dogs, from a maker that meets 4 of WSAVA's 5 questions) compared head-to-head on WSAVA manufacturer-quality criteria, AAFCO substantiation, monthly cost, and which dog each is best for in 2026. Eukanuba meets 4 of 5 WSAVA criteria. Eukanuba is roughly 7% less than Blue Buffalo.

The verdict

Eukanuba meets 4 of 5 WSAVA criteria and has Mars-grade manufacturing systems, but its adult label says "formulated to meet" AAFCO profiles instead of citing feeding trials; Blue Buffalo meets 2 of 5, uses formulation-only substantiation, and still relies partly on co-manufacturers. Blue Buffalo counters with strong ingredient transparency and General Mills' scale since 2018, at $50-90/month versus Eukanuba's $50-80.

Choose Eukanuba for the stronger WSAVA record (4 of 5 against 2) and performance formulations suited to working or active dogs. Choose Blue Buffalo only if you specifically prioritize ingredient-list transparency over WSAVA manufacturer-quality criteria. If the stronger WSAVA record is your bar, Eukanuba is the clear pick; Blue Buffalo's edge is its consumer-facing ingredient story.
