- 1protein animalbeef
Real meat. Dense in protein and iron. Some dogs are sensitive to it, but for most it's an excellent base.
Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 2protein animalchicken meal
Chicken with the water cooked out. Per pound, packs more protein than fresh chicken. See why →
Position 2: co-primary protein. Two named animal proteins in the top 2 is a strong protein build.
- 3grainoats
Whole grain. Steady energy, soluble fiber, and well-tolerated by most dogs.
Position 3: major carbohydrate source.
- 4grainbarley
Whole grain with a low glycemic profile and some soluble fiber. Easy on blood sugar.
Position 4: supporting grain. Smaller contribution to the carb deck.
- 5grainbrown rice
Whole grain that's easy to digest. Steady carb energy plus a little fiber.
Position 5: supporting grain. Smaller contribution to the carb deck.

Turkey with the water cooked out. Per pound, packs more protein than fresh turkey. See why →
Position 6: supporting protein. Modest contribution to total protein weight.
- 7fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid. See why →
Position 7: trace fat. Below the level that materially shifts the fat profile.

Natural prebiotic. Feeds beneficial gut bacteria. The same compound (inulin) used in human gut-health products.
- 19mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
