37 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
    chickpeas

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

  4. 4
    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 →

  5. 5
    chickpea flour
  6. 6
    sunflower oil

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

  7. 7
    natural flavor

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

  8. 8
    flaxseed

    Plant source of omega-3. Helpful for skin and coat, though dogs absorb omega-3 from fish more efficiently.

  9. 9
    dehydrated alfalfa meal

    Dried alfalfa. Fiber and trace minerals. Not exciting but it's a real plant ingredient.

  10. 10
    dicalcium phosphate

    Calcium and phosphorus combined. Required source of both minerals, especially in formulas without much bone content.

  11. 11
    salt

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

  12. 12
    choline chloride

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

  13. 13
    vitamin e supplement

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

  14. 14
    vitamin a supplement

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

  15. 15
    niacinamide
  16. 16
    d-calcium pantothenate

    B vitamin (B5). Standard inclusion in complete dog foods.

  17. 17
    riboflavin supplement

    B vitamin (B2). Required in complete dog foods. The standardized form ensures consistent dosing.

  18. 18
    vitamin d3 supplement

    The active form of vitamin D dogs need. Required for calcium absorption and bone health.

  19. 19
    thiamine mononitrate

    B vitamin (B1). Essential for nervous system function. Cooked-in vitamin loss is why thiamine is always added back.

  20. 20
    vitamin b12 supplement

    Essential for red blood cell formation and neurological function. Plant ingredients lack B12, so it has to be added.

  21. 21
    pyridoxine hydrochloride

    B vitamin (B6). Essential for protein metabolism. Standard inclusion in complete formulas.

  22. 22
    folic acid

    B vitamin (B9), essential for cell function. Standard in complete dog foods.

  23. 23
    biotin

    B vitamin that supports skin and coat health. Required for AAFCO-complete formulas.

  24. 24

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

  25. 25
    iron proteinate

    Iron bound to protein for better absorption. The premium form versus inorganic iron sulfate.
