  • 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.

Good Neutral Watch Flagged
  1. 1
    beef meal

    Beef cooked down to a dry concentrate. More protein per pound than fresh beef.

  2. 2
    chicken fat

    Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid.

  3. 3
    pea starch

    Refined starch from peas, mostly carbs after the protein is removed. Counts toward the legume stack the FDA examined.

  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
    pea protein

    Concentrated plant protein. Inflates the protein number on the label without matching the amino acid quality of meat.

  6. 6
    dried yeast

    Natural source of B vitamins and trace minerals. Adds a savory flavor that dogs respond well to.

  7. 7
    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.

  8. 8
    egg

    Whole eggs. The highest-quality protein on any ingredient label, by amino acid score.

  9. 9
    flaxseed

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

  10. 10
    l-carnitine

    Amino acid derivative that helps the body convert fat into energy. Common in weight-management formulas.

  11. 11
    dl-methionine

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

  12. 12
    taurine

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

  13. 13
    glucosamine hydrochloride

    Joint-support compound. Most useful in larger doses for older dogs. The kibble dose is real but modest.

  14. 14
    chondroitin sulfate
  15. 15
    salt

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

  16. 16
    potassium chloride

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

  17. 17
    choline chloride

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

  18. 18
    vitamin e supplement

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

  19. 19
    niacin supplement

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

  20. 20
    calcium pantothenate

    Same as d-calcium pantothenate. Vitamin B5 in standardized form.

  21. 21
    vitamin a supplement

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

  22. 22
    riboflavin supplement

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

  23. 23
    thiamine mononitrate

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

  24. 24
    pyridoxine hydrochloride

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

  25. 25
    biotin

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