  1. 1
    trout
  2. 2
    salmon meal

    Salmon cooked into a dry concentrate. Carries both protein and natural omega-3s in one ingredient.

  3. 3
    chickpeas

    Also called garbanzo beans. Affordable plant protein source, part of the legume stack the FDA examined in its heart-disease investigation. See why →

  4. 4
    peas

    Cheap protein bulk. Fine in small amounts, but when peas stack with lentils and chickpeas in the top ingredients, it's the pattern the FDA flagged in its heart-disease investigation. See why →

  5. 5
    dehydrated alfalfa meal

    Dried alfalfa. Fiber and trace minerals. Not exciting but it's a real plant ingredient.

  6. 6
    sunflower oil

    Common plant oil. Useful in moderation for omega-6, though too much skews the omega ratio against the dog's favor.

  7. 7
    natural flavor

    Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.

  8. 8
    salmon oil

    Pure omega-3s. The thing skin-and-coat formulas are usually built around.

  9. 9
    flaxseed

    Plant source of omega-3. Helpful for skin and coat, though dogs absorb omega-3 from fish more efficiently.

  10. 10
    potassium chloride

    Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.

  11. 11
    calcium carbonate

    Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.

  12. 12
    tricalcium phosphate

    Calcium and phosphorus source. Same role as dicalcium phosphate, slightly different ratio.

  13. 13
    choline chloride

    Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.

  14. 14
    salt

    Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.

  15. 15
    vitamin e supplement

    Required nutrient and a natural antioxidant. Often pulls double duty as a preservative.

  16. 16
    vitamin a supplement

    Vitamin A in stable, standardized form. Required for vision, immune function, and growth.

  17. 17
    niacinamide

    d-calcium pantothenate

    riboflavin supplement

    B vitamin (B2). Required in complete dog foods. The standardized form ensures consistent dosing.

  20. 20
    thiamine mononitrate

    B vitamin (B1). Essential for nervous system function. Cooked-in vitamin loss is why thiamine is always added back.

  21. 21
    vitamin b12 supplement

    Essential for red blood cell formation and neurological function. Plant ingredients lack B12, so it has to be added.

  22. 22
    pyridoxine hydrochloride

    B vitamin (B6). Essential for protein metabolism. Standard inclusion in complete formulas.

  23. 23
    folic acid
