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
    chicken meal

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

  3. 3
    brewers dried yeast

    Yeast left over from brewing. Rich in B vitamins and amino acids. A traditional and well-tolerated inclusion.

  4. 4
    cassava root flour
  5. 5
    animal fat preserved with mixed-tocopherols
  6. 6
    potato protein

    Concentrated potato protein. Like pea protein, it inflates the protein number without matching meat-quality amino acids.

  7. 7
    natural flavor

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

  8. 8
    coconut oil

    Saturated fat with medium-chain triglycerides. Mostly marketing in the doses kibble uses, but harmless.

  9. 9
    pea protein

    Concentrated plant protein. Inflates the protein number on the label without matching the amino acid quality of meat.

  10. 10
    glycerin

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

  11. 11
    mono and dicalcium phosphate

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

  12. 12
    potassium chloride

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

  13. 13
    soybean oil

    Plant oil. High in omega-6, which is required but commonly oversupplied. Fine in moderation.

  14. 14
    salt

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

  15. 15
    l-lysine monohydrochloride

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

  16. 16
    dried colostrum
  17. 17
    fish oil

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

  18. 18
    calcium carbonate

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

  19. 19
    pumpkin

    Soluble fiber that supports stool quality. Mild and well-tolerated.

  20. 20
    vitamin e supplement

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

  21. 21
    zinc proteinate

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

  22. 22
    taurine

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

  23. 23
    choline chloride

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

  24. 24
    dl-methionine

    Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.

  25. 25
    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.
