The scores
Blue Buffalo Life Protection: B grade, 78/100
Wellness Complete Health: B grade, 82/100
A 4-point gap within the same letter grade. Both are genuinely good dog foods — the kind you can feel confident feeding your dog. But Wellness earns those extra points through meaningful functional ingredients that Blue Buffalo doesn't match.
How the ingredients compare
Here are the top five ingredients side by side:
Blue Buffalo: Deboned Chicken, Chicken Meal, Brown Rice, Oatmeal, Barley
Wellness: Deboned Chicken, Chicken Meal, Oatmeal, Ground Barley, Peas
The top two ingredients are identical — deboned chicken for fresh protein and chicken meal for concentrated protein. Both follow with wholesome grains (brown rice and oatmeal for Blue Buffalo; oatmeal and ground barley for Wellness). Wellness introduces peas at position five, a protein-rich legume that also adds fiber, while Blue Buffalo uses barley, a nutritious whole grain.
Where Wellness pulls ahead
Wellness includes salmon oil, which is one of the best natural sources of EPA and DHA omega-3 fatty acids. These support skin and coat health, reduce inflammation, and benefit brain function. Blue Buffalo uses generic "fish oil" lower in its ingredient list, but salmon oil is generally considered a more premium and specific source.
Chicory root extract in Wellness provides inulin, a prebiotic fiber that feeds beneficial gut bacteria. Wellness also includes glucosamine and chondroitin — joint-support compounds that are especially valuable for medium and large breed dogs or aging dogs. These functional extras are what push Wellness from a 78 to an 82.
Wellness also avoids the pea protein concentrates and pea starch that appear in Blue Buffalo's formula. While peas themselves are fine, multiple pea derivatives can artificially inflate protein content on the guaranteed analysis — a practice called "protein splitting." Shop on Amazon →
Where Blue Buffalo holds its own
Blue Buffalo includes brown rice in its top five — one of the more nutritious grain choices available in dog food, providing fiber, B vitamins, and manganese. The formula also includes Blue Buffalo's signature "LifeSource Bits," a blend of antioxidants, vitamins, and minerals that the company claims are cold-formed to preserve potency.
Blue Buffalo is also more widely available than Wellness in most retail channels, and it frequently runs promotions that bring the per-pound price closer to mid-tier brands. If availability and price sensitivity are factors, Blue Buffalo is easier to find and occasionally cheaper. Shop on Amazon →
The bottom line
Wellness Complete Health (B/82) earns the edge over Blue Buffalo Life Protection (B/78) thanks to salmon oil, chicory root prebiotics, and glucosamine/chondroitin — functional ingredients that provide tangible health benefits. Blue Buffalo is a perfectly solid food, but at similar price points, Wellness delivers more for your money.
Both are strong B-grade choices, and either would be a significant upgrade over the C and D grade foods that dominate store shelves. If you want to go even higher, Fromm (B/84) and Acana (B/88) push further into premium territory.
