The short answer: Tie at A (90/100). The matchup is two A-tier brands that argue against conventional kibble in different ways. Nature’s Logic sources every micronutrient from whole foods — no synthetic vitamins or minerals at all. Instinct Raw Boost coats extruded kibble with freeze-dried raw pieces — aiming for the convenience of kibble plus the nutrition density of raw feeding. Both A/90, no philosophical overlap.

The scores

Nature's Logic Canine Original Chicken Meal Feast: A (90/100) — Chicken Meal, Millet, Chicken Fat, Yeast Culture, Pumpkin Seed Flour.

Instinct Raw Boost Original Grain-Free Chicken Recipe: A (90/100) — Chicken, Chicken Meal, Peas, Tapioca, Chicken Fat.

How the ingredients compare

The top-five ingredients reveal the formulation split between these two brands:

Nature's Logic: Chicken Meal, Millet, Chicken Fat, Yeast Culture, Pumpkin Seed Flour

Instinct: Chicken, Chicken Meal, Peas, Tapioca, Chicken Fat

Both formulas earn the same v15 score, but the ingredient lineups tell different stories about how they got there — that is where the actual pick decision lives.

Where Nature's Logic pulls ahead

Zero synthetic vitamins or minerals: Nature’s Logic uses alfalfa concentrate, montmorillonite clay, spray-dried liver, kelp, and almonds as whole-food vitamin/mineral sources. Instinct uses a synthetic vitamin/mineral supplement panel typical of the kibble category. Shop on Amazon →

Grain-inclusive with millet: Millet at #2 supplies gluten-free ancient-grain carbohydrate structure. Instinct Raw Boost is grain-free with peas at #3 and tapioca at #4 — legume and refined-starch structure that the FDA grain-free DCM investigation flagged in primary positions.

Six named probiotic strains plus four fermentation enzymes: The deepest probiotic and enzyme stack of any A-tier kibble we’ve reviewed. Instinct includes named probiotic strains but fewer total. For dogs with chronic GI sensitivity, the Nature’s Logic depth is meaningful.

Where Instinct holds its own

Raw-coated kibble with freeze-dried pieces: Instinct Raw Boost blends freeze-dried raw chicken pieces into the extruded kibble — combining the convenience of dry kibble with the nutritional density of raw. The freeze-dried pieces are minimally processed; the extruded base provides the structural binding. This is a production-method innovation Nature’s Logic doesn’t attempt. Shop on Amazon →

Higher protein density in the lead: Two named animal proteins (chicken at #1, chicken meal at #2) at the top of the panel, with the freeze-dried raw chicken pieces as an additional concentrated animal-protein source. Nature’s Logic leads with chicken meal alone and reaches its 85% animal-protein density through total inclusion across the panel.

Wider retail distribution: Instinct is carried at most major pet retailers and at supermarkets with a pet section. Nature’s Logic is primarily available at independent pet stores, Chewy, and Amazon. For owners who want store-pickup convenience, Instinct has the distribution edge.

The bottom line

Nature’s Logic and Instinct Raw Boost both earn A/90 by reformulating standard kibble in different ways. Nature’s Logic reformulates the vitamin/mineral premix — whole foods replace synthetic isolates. Instinct reformulates the production model — freeze-dried raw pieces coat the extruded base. Both are A-tier; pick on whether you want the no-synthetic-supplement philosophy or the raw-coated-kibble convenience.
