Controversial ingredients · 1

  • sodium selenite
    Synthetic selenium source. Selenium is essential, but sodium selenite has a narrower safety margin than organic alternatives like selenium yeast. Better-formulated foods use the organic form.

Every flagged ingredient has a published basis (confirmed harm / regulatory action / precautionary). See methodology →

Good Neutral Watch Flagged
  1. 1
    pollock
  2. 2
    lentils

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

  3. 3
    pollock meal
  4. 4
    canola oil

    Plant oil. Some omega-3 from the parent plant, though dogs absorb it less efficiently than fish-derived omega-3. Fine in moderation.

  5. 5
    sweet potato

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

  6. 6
    ground flaxseed

    Cracked flaxseed for better digestibility. Same plant omega-3s as whole flaxseed, just easier for the dog to extract.

  7. 7
    natural flavor

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

  8. 8
    ground miscanthus grass

    Same as miscanthus grass. A plant fiber source, mostly there for stool quality.

  9. 9
    salt

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

  10. 10
    dl-methionine

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

  11. 11
    potassium chloride

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

  12. 12
    choline chloride

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

  13. 13
    taurine

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

  14. 14
    vitamin e supplement

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

  15. 15
    dried chicory root

    Natural prebiotic. Feeds beneficial gut bacteria. The same compound (inulin) used in human gut-health products.

  16. 16
    zinc proteinate

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

  17. 17
    zinc sulfate

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

  18. 18
    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.

  19. 19
    iron proteinate

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

  20. 20
    niacin supplement

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

  21. 21
    ferrous sulfate

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

  22. 22
    copper proteinate

    Copper bound to protein for better absorption. Common in better-formulated diets.

  23. 23
    copper sulfate

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

  24. 24
    vitamin a supplement

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

  25. 25
    manganese proteinate

    Manganese bound to protein for better absorption. The chelated form most premium brands use.
