Good Neutral Watch Flagged
  1. 1
    brewers rice

    Broken rice kernels left over from milling, usually destined for human beer-making. Cheaper than whole or even white rice. Same carbs, less nutrition than the brown version.

  2. 2
    barley

    Whole grain with a low glycemic profile and some soluble fiber. Easy on blood sugar.

  3. 3
    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.

  4. 4
    poultry by-product meal

    Unnamed poultry. The mix can include any combination of chicken, turkey, or other birds, with no traceability. Named by-product meals are fine. This one isn't.

  5. 5
    animal digest Flagged

    A liquid flavoring made from hydrolyzed animal tissue, sprayed onto kibble for palatability. Common, not directly harmful, but vague about source.

  6. 6
    glycerin

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

  7. 7
    animal fat preserved with mixed-tocopherols
  8. 8
    calcium carbonate

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

  9. 9
    inulin

    Prebiotic fiber that feeds beneficial gut bacteria. Same compound found in chicory root.

  10. 10
    potassium chloride

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

  11. 11
    mono and dicalcium phosphate

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

  12. 12
    sodium bicarbonate
  13. 13
    salt

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

  14. 14
    l-lysine monohydrochloride

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

  15. 15
    vitamin e supplement

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

  16. 16
    zinc proteinate

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

  17. 17
    choline chloride

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

  18. 18
    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.

  19. 19
    ferrous sulfate

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

  20. 20
    manganese proteinate

    Manganese bound to protein for better absorption. The chelated form most premium brands use.

  21. 21
    niacin supplement

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

  22. 22
    thiamine mononitrate

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

  23. 23
    calcium pantothenate

    Same as d-calcium pantothenate. Vitamin B5 in standardized form.

  24. 24
    vitamin a supplement

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

  25. 25
    riboflavin supplement

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