28 total
Good Neutral Watch Flagged
  1. 1
    lamb

    Real meat. Often used for dogs with chicken or beef sensitivities. Slightly higher fat content than chicken.

  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
    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
    whole grain corn

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

  6. 6
    soybean meal

    Concentrated soy protein. Cheap plant protein that pads the label number, common in budget formulas.

  7. 7
    wheat

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

  8. 8
    beef fat preserved with mixed tocopherols
  9. 9
    oat meal

    Alternate spelling of oatmeal. Gentle whole grain, steady carb energy, soluble fiber.

  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
    natural flavor

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

  12. 12
    soybean oil

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

  13. 13
    mono and dicalcium phosphate

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

  14. 14
    salt

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

  15. 15
    calcium carbonate

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

  16. 16
    potassium chloride

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

  17. 17
    carrots

    Real vegetable. Fiber, beta-carotene, and a small amount of antioxidant value.

  18. 18
    dried peas

    Cheap protein bulk. Fine in small amounts, but when peas stack with lentils and chickpeas in the top ingredients, it's the pattern the FDA flagged in its heart-disease investigation. See why →

  19. 19
    choline chloride

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

  20. 20
    malted barley extract
  21. 21
    taurine

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

  22. 22
    zinc sulfate

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

  23. 23
    ferrous sulfate

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

  24. 24
    manganese sulfate

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

  25. 25
    copper sulfate

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