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
    trout
  3. 3
    salmon meal

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

  4. 4
    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.

  5. 5
    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.

  6. 6
    dried egg product

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

  7. 7
    oat fiber
  8. 8
    natural flavor

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

  9. 9
    animal fat preserved with mixed-tocopherols
  10. 10
    fish oil

    Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.

  11. 11
    chicken

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

  12. 12
    mono and dicalcium phosphate

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

  13. 13
    potassium chloride

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

  14. 14
    vitamin e supplement

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

  15. 15
    calcium carbonate

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

  16. 16
    salt

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

  17. 17
    choline chloride

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

  18. 18
    glucosamine hydrochloride

    Joint-support compound. Most useful in larger doses for older dogs. The kibble dose is real but modest.

  19. 19
    zinc sulfate

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

  20. 20
    taurine

    Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.

  21. 21
    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.

  22. 22
    ferrous sulfate

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

  23. 23
    manganese sulfate

    Inorganic manganese. Functional but less well-absorbed than the chelated proteinate form.

  24. 24
    copper sulfate

    Inorganic copper. Standard, effective at small doses. Premium formulas tend to use copper proteinate instead.

  25. 25
    niacin supplement

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