Eukanuba vs Wellness CORE

Eukanuba (performance-oriented kibble for active and working dogs, from a maker that meets 4 of WSAVA's 5 questions) 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. Eukanuba meets 4 of 5 WSAVA criteria. Eukanuba is roughly 13% less than Wellness CORE.

The verdict

Eukanuba meets 4 of 5 WSAVA criteria and has Mars-grade manufacturing, but its adult label says "formulated to meet" AAFCO profiles instead of citing feeding trials; 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 keeps 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 is close: $50-80/month for Eukanuba, $55-95 for Wellness CORE.

Pick Eukanuba for the stronger WSAVA record (4 of 5 against 2) and performance formulations for working or active dogs. Pick Wellness CORE only if you specifically want higher protein content and accept partial WSAVA compliance. If your dog has cardiac risk, Eukanuba is the safer choice.
