Our Take

Purina Pro Plan wins this comparison hands down. It's cheaper ($68 vs $74/month for a 70lb dog), has better research backing, a cleaner recall record, and comparable ingredients. Blue Buffalo's "natural" marketing doesn't justify the higher price or the recall concerns.

The only reason to choose Blue Buffalo over Purina Pro Plan is if your dog specifically does better on a grain-free formula and you've tried Pro Plan without success. Otherwise, Purina Pro Plan is the smarter choice.

The Verdict

Winner: Purina Pro Plan

Better research, cleaner history, lower price, comparable nutrition. If you're deciding between these two, Purina Pro Plan is the clear winner for most dogs.
