The scores
Earthborn Holistic Primitive Natural: B (78/100) — Good. Double meat meals lead the formula, plus three named fish meals for omega-3s. Grain-free and legume-free.
Blue Buffalo Life Protection: B (78/100) — Good. Deboned chicken plus chicken meal lead, backed by whole grains (brown rice, oatmeal, barley).
How the ingredients compare
The top five ingredients:
Earthborn Holistic: Turkey Meal, Chicken Meal, Tapioca, Chicken Fat, Sweet Potato
Blue Buffalo: Deboned Chicken, Chicken Meal, Brown Rice, Oatmeal, Barley
These are two different formulation philosophies. Earthborn leads with two concentrated meat meals (turkey + chicken), then goes grain-free with tapioca and sweet potato as the carb base. Blue Buffalo opens with fresh deboned chicken plus chicken meal, then layers three whole grains for its carb foundation. Both approaches are legitimate — Earthborn is protein-dense per cup (meal-heavy), while Blue Buffalo offers more balanced nutrition with meaningful whole-grain fiber.
Further down, Earthborn adds salmon meal, Alaska pollock meal, and whiting meal — giving it three additional named fish sources that Blue Buffalo doesn't have. Blue Buffalo counters with its signature LifeSource Bits (a cold-formed antioxidant blend) and a broader vitamin and mineral premix.
What Blue Buffalo does well
Fresh meat up front: Deboned chicken as the first ingredient gives Blue Buffalo a palatability edge and delivers whole-meat nutrients (moisture-cooked, less processed) that meal-only formulas can't match. For dogs that are picky about kibble, fresh-meat-first formulas tend to win the taste test.
Whole-grain carb base: Brown rice, oatmeal, and barley together deliver fiber, B-vitamins, and slow-release energy. Earthborn's tapioca is effectively pure starch — gluten-free and hypoallergenic, but nutritionally thin compared to whole grains.
Brand track record: Blue Buffalo is the largest and most-studied of the "premium mainstream" brands. More feeding data, broader retail availability, and more peer-reviewed attention than Earthborn. Shop on Amazon →
What Earthborn Holistic does well
Legume-free grain-free: This is Earthborn's real differentiator. Most grain-free kibble is heavy on peas, lentils, and chickpeas — the exact ingredient pattern the FDA has been investigating in connection with canine dilated cardiomyopathy. Earthborn Primitive Natural is grain-free without stacking legumes, which is rare and genuinely useful for DCM-conscious owners.
Three named fish sources: Salmon meal, Alaska pollock meal, and whiting meal add up to meaningfully more marine protein than Blue Buffalo's formula. For dogs whose skin, coat, or joint health benefits from omega-3 density, that's a real edge. Shop on Amazon →
The bottom line
Blue Buffalo ties Earthborn Holistic on score but benefits from a significantly larger brand footprint — if you're picking between the two based on pure labels and availability, it's the safer default. Earthborn Holistic is a specifically-better pick for a narrower audience: owners who want grain-free without the DCM-adjacent legume stack and owners whose dogs respond well to high fish-based omega-3s. The scores are identical, so for most dogs, either is a legitimate B-tier choice. Read our full reviews of Earthborn Holistic and Blue Buffalo for the complete breakdown.
