Good Neutral Watch Flagged
  1. 1
    chicken by-product meal

    Ground organs, bone, and tissue. Nutritionally dense, especially the liver and gizzard fractions. Named species ('chicken') is what matters. Generic 'poultry by-product meal' is the one to worry about.

  2. 2
    chicken fat

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

  3. 3
    brown rice

    Whole grain that's easy to digest. Steady carb energy plus a little fiber.

  4. 4
    corn

    Whole corn is more nutritious than it gets credit for, with decent amino acids and steady carbs. The bigger concern is when corn dominates the top of the ingredient list at the expense of named meat.

  5. 5
    brewers rice

    Broken rice kernels left over from milling, usually destined for human beer-making. Cheaper than whole or even white rice. Same carbs, less nutrition than the brown version.

  6. 6
    wheat gluten

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

  7. 7
    wheat

    Whole wheat. Fine for most dogs, though a portion are sensitive. Not a quality concern, just a fit-for-your-dog question.

  8. 8
    corn gluten meal

    Concentrated corn protein. Inflates the protein percent on the label without matching meat-quality amino acids.

  9. 9
    natural flavors

    Same as natural flavor. Usually hydrolyzed liver or broth, adds palatability.

  10. 10
    fish oil

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

  11. 11
    dried plain beet pulp

    Beet fiber, with the sugar removed. Long unfairly maligned. It's a real soluble fiber that supports stool quality.

  12. 12
    vegetable oil

    Unnamed plant oil. Could be soy, canola, corn, or a blend. Named oils like sunflower or canola are more transparent.

  13. 13
    sodium silico aluminate

    Same role as sodium aluminosilicate. Anti-caking agent at trace inclusion.

  14. 14
    powdered cellulose

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

  15. 15
    calcium carbonate

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

  16. 16
    potassium chloride

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

  17. 17
    l-tyrosine
  18. 18
    sodium tripolyphosphate

    Preservative and texture agent in wet food. Functional at small doses, not a major concern, but some brands avoid it.

  19. 19
    potassium citrate

    Source of potassium. Sometimes added in urinary-support formulas to help manage urine pH.

  20. 20
    hydrolyzed yeast

    Yeast broken down with enzymes. Strong palatant plus a real source of B vitamins and amino acids.

  21. 21
    choline chloride

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

  22. 22
    taurine

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

  23. 23
    glucosamine hydrochloride

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

  24. 24
    salt

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

  25. 25
    l-carnitine

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