- 1protein animalwhitefish
Real fish meat. Lean protein with a clean amino acid profile.
Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 2protein animalherring meal
Concentrated herring with the water removed. Carries protein and omega-3s in one ingredient.
Position 2: co-primary protein. Two named animal proteins in the top 2 is a strong protein build.
- 3grainoatmeal
Gentle on the stomach. Slow-release carbs and soluble fiber that supports stool quality.
Position 3: major carbohydrate source.

Position 5: significant protein contributor. Adds amino-acid diversity to the top of the deck.
- 6fatcanola oil

Position 6: secondary fat. Often where marine oils sit when present alongside a primary land-animal fat.
- 7dried plain beet pulp
Beet fiber, with the sugar removed. Long unfairly maligned. It's a real soluble fiber that supports stool quality. See why →
Position 7: functional fiber for digestion or satiety.
- 8fatflaxseed
Plant source of omega-3. Helpful for skin and coat, though dogs absorb omega-3 from fish more efficiently.
Position 8: trace fat. Below the level that materially shifts the fat profile.
- 9othernatural flavor
Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.

- 24mineralzinc proteinate
Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.
