Good Neutral Watch Flagged
  1. 1
    chicken

    Real meat. Primary protein source, with the amino acid profile dogs actually evolved to eat.

  2. 2
    chicken meal

    Chicken with the water cooked out. Per pound, packs more protein than fresh chicken.

  3. 3
    rice

    Generic rice. Could be white or brown, the label doesn't say. Brown rice would be specified if it were.

  4. 4
    yellow corn
  5. 5
    ground wheat

    Whole wheat. Fine for most dogs, though a portion are sensitive. Not a quality concern, just a fit-for-your-dog question.

  6. 6
    corn protein meal

    Concentrated corn protein. Similar in role to corn gluten meal, pads the protein number on the label without matching meat amino acids.

  7. 7
    animal fat preserved with mixed-tocopherols
  8. 8
    dried beet pulp

    Soluble fiber from sugar-beet processing. Sometimes treated as a filler, but it's actually one of the better fiber sources in kibble.

  9. 9
    dried yeast

    Natural source of B vitamins and trace minerals. Adds a savory flavor that dogs respond well to.

  10. 10
    powdered cellulose

    Plant fiber, often from wood pulp. Cheap bulk filler. Not harmful, but a tell that the recipe is reaching for inexpensive bulk.

  11. 11
    liver flavor
  12. 12
    dried egg product

    Whole eggs with the water removed. Same nutritional value as fresh eggs, just shelf-stable.

  13. 13
    glycerin

    Humectant used in soft-moist foods to keep them chewy. Safe in moderation but a signal of a processed semi-moist product.

  14. 14
    salt

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

  15. 15
    potassium chloride

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

  16. 16
    calcium carbonate

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

  17. 17
    phosphoric acid
  18. 18
    mono and dicalcium phosphate

    Source of calcium and phosphorus. Standard inclusion in complete dog foods.

  19. 19
    vitamin e supplement

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

  20. 20
    choline chloride

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

  21. 21
    l-lysine monohydrochloride

    Stable form of L-lysine, an essential amino acid. Common in plant-heavy formulas to balance the amino acid profile.

  22. 22
    l-ascorbyl-2-polyphosphate

    A stable form of vitamin C used in pet food. Provides antioxidant support and survives processing better than plain ascorbic acid.

  23. 23
    zinc sulfate

    Inorganic zinc. Effective at AAFCO doses but less well-absorbed than chelated forms like zinc proteinate.

  24. 24
    ferrous sulfate

    Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.

  25. 25
    niacin supplement

    B vitamin (B3). Required in complete dog foods, added as a supplement to standardize the dose.
