22 total
Good Neutral Watch Flagged
  1. 1
    water

    Just water. Counted on the label of any wet or fresh food. The number tells you the moisture content.

  2. 2
    duck

    Real meat. Often used as a novel protein for dogs with sensitivities to chicken or beef.

  3. 3
    potato

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

  4. 4
    duck liver
  5. 5
    potato starch

    Refined potato. Pure carb energy, low on other nutrition. Often used as a binder in grain-free recipes.

  6. 6
    soybean oil

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

  7. 7
    fish oil

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

  8. 8
    powdered cellulose

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

  9. 9
    dicalcium phosphate

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

  10. 10
    calcium carbonate

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

  11. 11
    salt

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

  12. 12
    dl-methionine

    Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.

  13. 13
    potassium chloride

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

  14. 14
    choline chloride

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

  15. 15
    l-tryptophan

    Essential amino acid. Sometimes added in calming or weight-management formulas.

  16. 16
    zinc oxide

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

  17. 17
    ferrous sulfate

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

  18. 18
    manganese sulfate

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

  19. 19
    copper sulfate

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

  20. 20
    calcium iodate

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

  21. 21
    taurine

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

  22. 22
    beta-carotene
