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 broth
  3. 3
    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 →

  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
    alfalfa meal

    Dried alfalfa. Real fiber and trace minerals. Functional plant ingredient.

  6. 6
    agar-agar

    Seaweed-derived gel used as a thickener. Functional alternative to carrageenan, generally well-tolerated.

  7. 7
    tricalcium phosphate

    Calcium and phosphorus source. Same role as dicalcium phosphate, slightly different ratio.

  8. 8
    potassium chloride

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

  9. 9
    taurine

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

  10. 10
    salt

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

  11. 11
    vitamin e supplement

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