72 total
Good Neutral Watch Flagged
  1. 1
    duck

    Real meat. Often used as a novel protein for dogs with sensitivities to chicken or beef.

  2. 2
    duck meal

    Duck cooked into a dry concentrate. Per pound, more protein than fresh duck.

  3. 3
    sweet potato

    Complex carb with fiber and beta-carotene. Gentle on the stomach.

  4. 4
    chickpeas

    Also called garbanzo beans. Affordable plant protein source, part of the legume stack the FDA examined in its heart-disease investigation. See why →

  5. 5
    whitefish meal

    Whitefish cooked into a dry concentrate. Strong protein source, common in premium formulas.

  6. 6
    lentils

    Same concern as peas. Affordable plant protein, but when they pile up in the top 5 ingredients, it's a flag. See why →

  7. 7
    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 →

  8. 8
    sunflower oil

    Common plant oil. Useful in moderation for omega-6, though too much skews the omega ratio against the dog's favor.

  9. 9
    tapioca starch

    Refined cassava starch, used as a binder. Easy to digest, low on nutrition.

  10. 10
    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.

  11. 11
    coconut oil

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

  12. 12
    apple cider vinegar
  13. 13
    turmeric

    Spice with anti-inflammatory compounds. Real research in humans, but the dose in kibble is small. Mostly there for label appeal.

  14. 14
    black pepper
  15. 15
    ginger

    Real spice. Some anti-nausea evidence in humans, but the dose in kibble is small. Mostly for flavor.

  16. 16
    bovine colostrum
  17. 17
    blueberries

    Antioxidants, real. But the amount in any kibble is too small to do much. Mostly marketing.

  18. 18
    cranberries

    Often added with a urinary-tract-support marketing angle. Real cranberry compounds help in concentrate form, but kibble doses are small.

  19. 19
    goji berries
  20. 20
    tart cherries
  21. 21
    pomegranate

    Antioxidants, real. Like other fruit additions, the dose in kibble is mostly cosmetic.

  22. 22
    pineapple
  23. 23
    papaya
  24. 24
    apple

    Real fruit, some fiber and antioxidants. The amount in kibble is too small to matter much.

  25. 25
    dried kelp

    Natural source of iodine and trace minerals. A common premium-brand inclusion.
