Blue Buffalo vs Nutro

Blue Buffalo (mid-premium kibble marketed on ingredient quality; partial WSAVA compliance) and Nutro (premium-tier kibble from Mars Petcare, 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. Nutro meets 4 of 5 WSAVA criteria. Nutro is roughly 11% less than Blue Buffalo.

The verdict

Nutro meets 4 of 5 WSAVA questions at $55-70/month, and Blue Buffalo meets 2 of 5 at $50-90/month. The prices overlap heavily, so Nutro is simply the better documented of the two. PhD nutrition scientists that Mars Petcare has on record stand behind it, its FAQ lists owned dry-food factories in Henderson, NC and Victorville, CA, and it describes testing and HACCP for all Nutro facilities. Blue Buffalo reports owning about 80% of its plants and uses a co-manufacturer.

Blue Buffalo remains the choice for owners who weigh ingredient-list transparency above everything else. Nutro suits owners who want a premium kibble from a parent company with PhD nutrition scientists on record. Blue Buffalo's label and Nutro's FAQ both say "formulated to meet" AAFCO profiles, so neither brings feeding trials. A dog with medical needs should eat what a veterinarian recommends.
