Is Nature's Logic or Wellness CORE better for dogs?

Effectively tied at A/90 vs A/90 on the v15 rubric. Nature's Logic Canine Original Chicken Meal Feast is whole-food / zero-synthetic-premix — every micronutrient from whole-food sources like alfalfa concentrate, spray-dried liver, almonds, and montmorillonite clay. Grain-inclusive (millet first carb), meal-first protein density. Wellness CORE Original Grain-Free leads with three named animal proteins (deboned chicken + chicken meal + turkey meal in positions 1-3) and grain-free pea + potato carbohydrate base with conventional synthetic-premix supplementation. Pick Nature's Logic for whole-food formulation philosophy and grain-inclusive DCM-watchlist avoidance. Pick Wellness CORE for grain-free high-protein density and broader retail availability.

What does 'zero synthetic vitamins or minerals' actually mean in dog food?

It means the formula substantiates AAFCO nutritional adequacy entirely from whole-food ingredients without adding isolated synthetic vitamin or mineral supplements. Most commercial dog foods add synthetic vitamin/mineral premix to guarantee specific AAFCO compliance margins on each named nutrient (synthetic forms like vitamin E supplement, zinc proteinate, calcium iodate, sodium selenite, etc.). Whole-food-only formulation requires sourcing each AAFCO-required nutrient from a named whole-food ingredient: alfalfa concentrate for vitamin K and magnesium, spray-dried liver for B-vitamins and folate and iron, almonds for vitamin E, montmorillonite clay for trace minerals, yeast culture for B-vitamins, etc. The trade-off: whole-food-only sources vary with seasonal sourcing and harvest variability so batch-to-batch AAFCO margins are less precise than synthetic-premix supplementation. For owners specifically prioritizing whole-food formulation philosophy (the dietary equivalent of preferring real-food vitamin C from oranges over isolated ascorbic acid supplementation), Nature's Logic is structurally unique.

Is the FDA's grain-free DCM watchlist a real concern for Wellness CORE?

Not for Wellness CORE specifically, but the formulation pattern is the structural class FDA monitored. The FDA's 2018-2022 investigation into a potential association between grain-free formulations and DCM (dilated cardiomyopathy) in dogs flagged grain-free formulations using pulses (peas, lentils, chickpeas) as the primary carbohydrate source. The investigation named specific brands more frequently associated with reported cases — Wellness CORE was not in the top-named-brand list. The FDA closed active investigation in 2022 without a definitive causal mechanism identified. However: many veterinary cardiology researchers continue to recommend grain-inclusive formulations for breeds with elevated DCM risk (Doberman Pinschers, Golden Retrievers, Great Danes, Boxers, Cocker Spaniels). For owners with DCM-risk-breed dogs specifically, grain-inclusive premium kibbles (like Nature's Logic) are the structurally cautious pick. For owners with low-DCM-risk-breed dogs and a preference for grain-free high-protein formulation, Wellness CORE Original remains a solid A-tier pick.

The short answer: Effectively tied at A/90 vs A/90 on the v15 rubric. Both are A-tier premium kibbles but on opposite ends of the formulation philosophy spectrum. Nature’s Logic Canine Original Chicken Meal Feast is whole-food / zero-synthetic-premix — every micronutrient comes from whole-food sources like alfalfa concentrate, montmorillonite clay, spray-dried liver, almonds, and yeast culture. The formula is grain-inclusive (millet first carb) with no synthetic vitamins or minerals at all. Wellness CORE Original Grain-Free is triple-named-protein high-protein — deboned chicken, chicken meal, and turkey meal across the first three ingredients with peas and potatoes as the grain-free carbohydrate base. Pick on whole-food fundamentalism vs grain-free high-protein density.

The scores

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

Wellness CORE Original Grain-Free Chicken, Turkey & Chicken Meal: A (90/100) — Deboned Chicken, Chicken Meal, Turkey Meal, Peas, Potatoes.

How the ingredients compare

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

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

Wellness CORE: Deboned Chicken, Chicken Meal, Turkey Meal, Peas, Potatoes

Both products earn effectively 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 — AAFCO substantiation entirely from whole-food sources: Nature’s Logic is one of the only US dry dog foods that substantiates AAFCO completeness entirely from whole-food sources. Every micronutrient comes from named whole-food ingredients: alfalfa concentrate (vitamin K, magnesium), montmorillonite clay (trace minerals), spray-dried liver (B-vitamins, vitamin A, folate, choline, iron, copper, zinc), almonds (vitamin E, magnesium), yeast culture (B-vitamins, beta-glucans), and pumpkin seed flour (zinc, magnesium, omega-6). Wellness CORE uses standard synthetic vitamin/mineral premix (zinc proteinate, copper proteinate, vitamin E supplement, vitamin D3 supplement, calcium iodate, sodium selenite). For owners specifically prioritizing whole-food-only formulation philosophy (the dietary equivalent of preferring real-food vitamin C from oranges over ascorbic-acid supplementation), Nature’s Logic is structurally unique at this score tier and across the entire dry dog food category.

Millet-first grain-inclusive structure for owners concerned about grain-free DCM watchlist: Nature’s Logic uses millet (#2) as the primary carbohydrate — an ancient, naturally gluten-free, nutrient-dense whole grain. Grain-inclusive formulation sidesteps the FDA’s 2018-2022 ongoing DCM (dilated cardiomyopathy) watchlist that flagged certain grain-free formulations rich in pulses (peas, lentils, chickpeas) as potentially associated with DCM in dogs. Wellness CORE is grain-free with peas (#4) and potatoes (#5) in the formulation — not on the FDA-named-brand list of watchlist concern but structurally similar to formulations that were. For owners specifically wanting to avoid the FDA DCM watchlist formulation pattern while staying in A-tier kibble territory, Nature’s Logic’s grain-inclusive structure is the structurally aligned pick.

Multi-protein meal-form ingredient density + no fresh-meat moisture inflation: Nature’s Logic leads with chicken meal (#1) — the rendered, water-removed form that delivers concentrated protein density per cup (chicken meal is ~65-70% protein by weight vs ~18% for fresh deboned chicken which is ~70% water). This means more usable protein per cup than formulas that lead with fresh deboned chicken in raw position (where most of the displayed protein-by-weight is water that cooks off in extrusion). Wellness CORE leads with deboned chicken (fresh, ~70% water), then chicken meal (#2) and turkey meal (#3) — the meal-form structural-protein anchors are pushed deeper. For owners specifically interested in maximum protein density per cup at the lowest possible ingredient-deck inflation, Nature’s Logic’s meal-first structure is the structurally aligned pick.

Where Wellness CORE holds its own

Triple-named-protein grain-free high-protein density (deboned chicken + chicken meal + turkey meal in positions 1-3): Wellness CORE Original packs three named animal proteins into the first three ingredient positions: deboned chicken, chicken meal, and turkey meal. The result is one of the higher analyzed-protein-percentage commercial grain-free kibbles (typically 34% protein on guaranteed analysis vs 24% for grain-inclusive premium kibbles). For owners specifically wanting high-protein grain-free formulation density and the metabolic activity profile that comes with it (sustained energy for active dogs, leaner body-composition tendencies, satiety per cup), Wellness CORE Original is structurally aligned. Nature’s Logic is also high-protein density but anchors that density through chicken meal first rather than triple-named-protein loading. Shop on Amazon →

Wider retail distribution + brand recognition + fuller life-stage range: Wellness CORE is widely distributed at PetSmart, Petco, Walmart, Target, Amazon, Chewy, Tractor Supply, and most independent pet stores, with a full line (Original, Reduced Fat, Senior, Small Breed, Puppy, Large Breed Adult, plus CORE Tender Bites Air-Dried, CORE Raw Rev, and the Bowl Boosters topper line). Nature’s Logic is distributed primarily at independent natural-pet retailers and Amazon — substantially thinner shelf footprint and fewer formula variants. For owners specifically prioritizing broad retail availability or multi-variant brand range, Wellness CORE is structurally aligned.

Conventional synthetic-premix supplementation gives precise AAFCO compliance margin: Wellness CORE uses standard synthetic vitamin/mineral premix — chelated zinc proteinate, copper proteinate, vitamin E supplement, vitamin D3, calcium iodate, sodium selenite, plus B-complex vitamins. The synthetic-premix approach delivers precise AAFCO compliance margins on each named nutrient at every batch — structural reliability that is harder to guarantee from whole-food-only sources where micronutrient density varies with seasonal sourcing and harvest variability. For owners specifically prioritizing batch-to-batch AAFCO-margin consistency on every named nutrient, Wellness CORE’s synthetic-premix approach is the structurally aligned pick.

The bottom line

Effectively tied at A/90 vs A/90 — the pick comes down to formulation philosophy, not score gap. Pick Nature’s Logic Canine Original for zero-synthetic-premix whole-food-only AAFCO substantiation (every micronutrient from whole-food sources like alfalfa concentrate, spray-dried liver, almonds, montmorillonite clay), millet-first grain-inclusive structure that sidesteps the FDA grain-free DCM watchlist, and meal-first protein density for maximum usable protein per cup. Pick Wellness CORE Original for triple-named-protein grain-free high-protein density (deboned chicken + chicken meal + turkey meal in the first three positions), broader retail distribution, fuller life-stage range across the brand family, and conventional synthetic-premix supplementation that delivers precise batch-to-batch AAFCO-margin consistency. Both are A-tier premium kibbles — the philosophical split is the actual decision point.
