Good Neutral Watch Flagged
  1. 1
    whole grain corn

    Whole corn with the kernel intact. Decent fiber and B vitamins, though it can crowd out meat in cheaper recipes.

  2. 2
    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.

  3. 3
    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.

  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
    barley

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

  6. 6
    animal fat preserved with mixed-tocopherols
  7. 7
    pea fiber

    Insoluble fiber from peas. Doesn't carry the protein-inflation concern of pea protein. Mostly there for stool quality.

  8. 8
    glycerin

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

  9. 9
    natural flavor

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

  10. 10
    mono and dicalcium phosphate

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

  11. 11
    wheat bran
  12. 12
    dried whey
  13. 13
    potassium chloride

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

  14. 14
    salt

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

  15. 15
    fish oil

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

  16. 16
    l-lysine monohydrochloride

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

  17. 17
    calcium carbonate

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

  18. 18
    choline chloride

    Essential nutrient for liver and brain function. 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
    zinc sulfate

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

  21. 21
    ferrous sulfate

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

  22. 22
    niacin supplement

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

  23. 23
    manganese sulfate

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

  24. 24
    vitamin a supplement

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

  25. 25
    calcium pantothenate

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