Good Neutral Watch Flagged
  1. 1
    chicken broth

    Real broth, adds flavor and moisture. Negligible nutrition on its own but tells you the recipe leans on real meat.

  2. 2
    pork liver

    Organ meat. Dense in B vitamins, iron, and vitamin A. Among the most nutritious ingredients on any label.

  3. 3
    carrots

    Real vegetable. Fiber, beta-carotene, and a small amount of antioxidant value.

  4. 4
    powdered cellulose

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

  5. 5
    corn starch
  6. 6
    green peas

    Same as peas. Useful in small amounts. The concern is when pulses dominate the top of the ingredient list. See why →

  7. 7
    tuna
  8. 8
    wheat gluten

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

  9. 9
    dried tomato pomace

    The fiber-rich byproduct of tomato processing. Sometimes flagged unfairly. It's a real fiber source, not a filler shortcut.

  10. 10
    soybean oil

    Plant oil. High in omega-6, which is required but commonly oversupplied. Fine in moderation.

  11. 11
    hydrolyzed chicken flavor

    Hydrolyzed chicken used as a palatability enhancer. Real ingredient, tiny inclusion, no quality signal either way.

  12. 12
    chicken liver flavor

    Hydrolyzed chicken liver used as a flavor enhancer. Real ingredient, used in tiny amounts for palatability.

  13. 13
    rice

    Generic rice. Could be white or brown, the label doesn't say. Brown rice would be specified if it were.

  14. 14
    potassium alginate
  15. 15
    coconut oil

    Saturated fat with medium-chain triglycerides. Mostly marketing in the doses kibble uses, but harmless.

  16. 16
    fish oil

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

  17. 17
    flaxseed

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

  18. 18
    calcium chloride
  19. 19
    guar gum

    Thickener common in wet food. Emerging research on emulsifiers and the gut microbiome, but no smoking gun in dogs yet.

  20. 20
    dicalcium phosphate

    Calcium and phosphorus combined. Required source of both minerals, especially in formulas without much bone content.

  21. 21
    potassium chloride

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

  22. 22
    calcium lactate

    Calcium source from lactic acid fermentation. Functional, well-tolerated.

  23. 23
    calcium gluconate
  24. 24
    monosodium phosphate

    Mineral source and preservative. Standard inclusion at small doses.

  25. 25
    vitamin e supplement

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