Good Neutral Watch Flagged
  1. 1
    beef

    Real meat. Dense in protein and iron. Some dogs are sensitive to it, but for most it's an excellent base.

  2. 2
    ocean fish meal
  3. 3
    salmon meal

    Salmon cooked into a dry concentrate. Carries both protein and natural omega-3s in one ingredient.

  4. 4
    sweet potato

    Complex carb with fiber and beta-carotene. Gentle on the stomach.

  5. 5
    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 →

  6. 6
    pea starch

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

  7. 7
    chicken fat

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

  8. 8
    fava beans

    Less common pulse. Same concern as peas when stacked with other legumes.

  9. 9
    dried eggs

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

  10. 10
    dried tomato pomace

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

  11. 11
    animal plasma
  12. 12
    natural flavor

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

  13. 13
    spray dried animal blood cells
  14. 14
    carrots

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

  15. 15
    salmon oil

    Pure omega-3s. The thing skin-and-coat formulas are usually built around.

  16. 16
    pumpkin

    Soluble fiber that supports stool quality. Mild and well-tolerated.

  17. 17
    salt

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

  18. 18
    potassium chloride

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

  19. 19
    blueberries

    Antioxidants, real. But the amount in any kibble is too small to do much. Mostly marketing.

  20. 20
    cranberries

    Often added with a urinary-tract-support marketing angle. Real cranberry compounds help in concentrate form, but kibble doses are small.

  21. 21
    choline chloride

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

  22. 22
    zinc sulfate

    Inorganic zinc. Effective at AAFCO doses but less well-absorbed than chelated forms like zinc proteinate.

  23. 23
    ferrous sulfate

    Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.

  24. 24
    copper sulfate

    Inorganic copper. Standard, effective at small doses. Premium formulas tend to use copper proteinate instead.

  25. 25
    manganese sulfate

    Inorganic manganese. Functional but less well-absorbed than the chelated proteinate form.
