Blue Buffalo vs Wellness CORE

Blue Buffalo (mid-premium kibble marketed on ingredient quality; partial WSAVA compliance) 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. Both brands meet 2 of 5 WSAVA criteria. Blue Buffalo is roughly 7% less than Wellness CORE.

The verdict

Two boutique kibbles with different gaps. Blue Buffalo meets 2 of the 5 WSAVA criteria and still uses some co-manufacturers, but offers strong ingredient transparency and General Mills' scale since 2018. Wellness CORE meets 2 of 5, owns its plants through Wellness Pet Company, and emphasizes higher protein, but still uses formulation-only substantiation and keeps no full-time board-certified veterinary nutritionist. Pricing is close: $50-90/month versus $55-95.

Both use formulation-only substantiation rather than feeding trials, and Blue Buffalo was named in 31 reports in the FDA's 2019 DCM update, while Wellness was not on that list, though some individual complaints name grain-free CORE recipes. Pick Blue Buffalo if ingredient-list transparency is your priority. Pick Wellness CORE if higher protein content and owned manufacturing matter more, and your dog has no cardiac risk. If you want a brand meeting all 5 WSAVA criteria, neither is the right choice.
