The short answer: Tie at A (90/100). The interesting matchup: both brands reject standard kibble formulation, but for opposite reasons. Nature’s Logic rejects the synthetic vitamin/mineral premix — every micronutrient comes from whole-food sources. Orijen rejects the carbohydrate-heavy formulation — roughly 85% of the formula is fresh animal protein, eggs, organs, and fish. Both clear A-tier, neither overlaps in philosophy with the other.

The scores

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

Orijen Original: A (90/100) — Fresh Chicken, Fresh Turkey, Fresh Whole Eggs, Fresh Chicken Liver, Fresh Whole Herring.

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

Orijen: Fresh Chicken, Fresh Turkey, Fresh Whole Eggs, Fresh Chicken Liver, Fresh Whole Herring

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 sources every required micronutrient from whole-food ingredients — alfalfa nutrient concentrate for vitamin K and B-complex, montmorillonite clay for trace minerals, spray-dried chicken liver for vitamin A and B12. Orijen carries a synthetic vitamin/mineral supplement panel typical of the category, even at its high animal-protein density. Shop on Amazon →

Six named probiotic strains plus four named fermentation enzymes: The deepest digestive-support stack of any A-tier kibble we’ve reviewed. Orijen lists fewer named bacterial strains. For dogs with chronic GI sensitivity, this matters.

Grain-inclusive with millet: Millet at #2 supplies a gluten-free ancient-grain carbohydrate base. Orijen is grain-free with red lentils, peas, and chickpeas in supporting positions — legumes the FDA’s 2018–2024 grain-free DCM investigation specifically flagged.

Where Orijen holds its own

WholePrey at ~85% animal-derived: Orijen’s top five ingredients are five different fresh animal sources — fresh chicken, fresh turkey, fresh whole eggs, fresh chicken liver, fresh whole herring. The brand publishes that 85% of the formula is animal-derived. Nature’s Logic reaches 85% animal-protein density through total inclusion across the panel but uses fewer animal sources in primary positions. Shop on Amazon →

Whole-fish marine omega-3: Fresh whole herring at #5 supplies marine EPA/DHA in its whole-fish form. Nature’s Logic uses menhaden fish meal further down the panel — still effective marine omega-3 source, but rendered rather than whole-fish.

Higher protein and fat density: Orijen’s guaranteed analysis runs higher on both protein (~38–42%) and fat (~18–20%) than Nature’s Logic (36% protein / 15% fat). For active or working dogs needing concentrated caloric density, Orijen’s carnivore-aligned macros have the edge.

The bottom line

Nature’s Logic and Orijen both earn A/90 from different conceptual directions. Nature’s Logic argues that what goes into the vitamin/mineral premix matters more than which animals provided the protein. Orijen argues that the animal protein density itself is the formula’s most important feature. Both are A-tier formulations; neither is a substitute for the other. For owners who want a millet-based grain-inclusive A-tier with whole-food micronutrient sourcing, Nature’s Logic. For owners who want maximum animal-protein density and don’t mind the legume-base grain-free structure, Orijen.
