Good Neutral Watch Flagged
  1. 1
    wheat gluten

    Concentrated wheat protein. Like other plant gluten meals, it pads the protein number on the label without contributing meat-quality amino acids.

  2. 2
    soy protein concentrate
  3. 3
    poultry by-product meal

    Unnamed poultry. The mix can include any combination of chicken, turkey, or other birds, with no traceability. Named by-product meals are fine. This one isn't.

  4. 4
    soybean germ meal
  5. 5
    fish meal

    Concentrated fish protein, usually whitefish, herring, or mackerel. Strong amino acid profile.

  6. 6
    pea protein

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

  7. 7
    corn starch
  8. 8
    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.

  9. 9
    powdered cellulose

    Plant fiber, often from wood pulp. Cheap bulk filler. Not harmful, but a tell that the recipe is reaching for inexpensive bulk.

  10. 10
    natural flavor

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

  11. 11
    fish oil

    Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.

  12. 12
    animal fat preserved with mixed-tocopherols
  13. 13
    sodium caseinate
  14. 14
    dried egg product

    Whole eggs with the water removed. Same nutritional value as fresh eggs, just shelf-stable.

  15. 15
    gelatin
  16. 16
    potassium chloride

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

  17. 17
    soy protein isolate
  18. 18
    calcium carbonate

    Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.

  19. 19
    inulin

    Prebiotic fiber that feeds beneficial gut bacteria. Same compound found in chicory root.

  20. 20
    tricalcium phosphate

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

  21. 21
    salt

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

  22. 22
    vitamin e supplement

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

  23. 23
    taurine

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

  24. 24
    choline chloride

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

  25. 25
    l-carnitine

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