27 total
Good Neutral Watch Flagged
  1. 1
    potato

    Standard white potato. Steady carb source, common starch in grain-free recipes.

  2. 2
    fish meal

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

  3. 3
    coconut oil

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

  4. 4
    potato protein

    Concentrated potato protein. Like pea protein, it inflates the protein number without matching meat-quality amino acids.

  5. 5
    natural flavors

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

  6. 6
    vegetable oil

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

  7. 7
    calcium carbonate

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

  8. 8
    l-tyrosine
  9. 9
    monocalcium phosphate

    Source of calcium and phosphorus. Standard mineral inclusion in complete dog foods.

  10. 10
    choline chloride

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

  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
    salt

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

  14. 14
    potassium chloride

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

  15. 15
    fish oil

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

  16. 16
    zinc proteinate

    Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.

  17. 17
    zinc oxide

    Inorganic zinc. Cheapest mineral form on the market. Functional but less bioavailable than chelated alternatives.

  18. 18
    ferrous sulfate

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

  19. 19
    manganese proteinate

    Manganese bound to protein for better absorption. The chelated form most premium brands use.

  20. 20
    manganous oxide

    Inorganic manganese. Functional, cheaper than chelated forms, less efficiently absorbed.

  21. 21
    copper sulfate

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

  22. 22
    copper proteinate

    Copper bound to protein for better absorption. Common in better-formulated diets.

  23. 23
    calcium iodate

    Source of iodine for thyroid function. Functional, required in complete formulas.

  24. 24
    glucosamine hydrochloride

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

  25. 25
    chondroitin sulfate

Showing first 25 of 27. Position 1-5 has the largest weight in the recipe.
