Protein Content
Taste of the Wild leads at 32% protein, followed closely by Blue Buffalo Wilderness variants. Hill's and Purina Pro Plan sit around 25-27%. IAMS comes in lowest but still adequate for most adult dogs.
Palatability
Every food was accepted by our test dogs, but Taste of the Wild and Blue Buffalo generated the most enthusiasm. Hill's Science Diet required moistening for some picky eaters. All others performed well.
Digestibility
Purina Pro Plan's live probiotics showed measurable digestive benefits. Taste of the Wild's probiotics also performed well. All foods produced healthy stools after transition periods.

Diamond Naturals offers the best value at $1.17/lb with premium ingredients. Taste of the Wild follows at $1.93/lb for grain-free. Premium brands like Blue Buffalo run $2.17/lb. IAMS offers budget value at $1.20/lb.
Taste of the Wild High Prairie
Why We Chose It
Best combination of premium ingredients, grain-free formula, and value pricing. The buffalo and venison proteins work well for dogs with sensitivities, and the proprietary probiotics support digestion.
For most dog owners seeking the best balance of quality, nutrition, and value, Taste of the Wild High Prairie wins. It delivers grain-free, high-protein nutrition with novel proteins at a price that undercuts most competitors. For budget-conscious owners, Diamond Naturals offers remarkable value. For veterinarian-recommended mainstream nutrition, Purina Pro Plan excels.
