CIP

Controversial ingredients · 2

  • carrageenan
    Seaweed-derived thickener; some studies link it to gastrointestinal inflammation. Most common in wet foods but appears in some kibble gravies.
  • sodium selenite
    Synthetic selenium source. Selenium is essential, but sodium selenite has a narrower safety margin than organic alternatives like selenium yeast. Better-formulated foods use the organic form.

Every flagged ingredient has a published basis (confirmed harm / regulatory action / precautionary). See methodology →

Good Neutral Watch Flagged
  1. 1
    water sufficient for processing

    The regulatory phrase for cooking water in wet food. Has no nutritional implication, just labeling formality.

  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
    dried potato

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

  6. 6
    duck by-product meal
  7. 7
    powdered cellulose

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

  8. 8
    vegetable oil

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

  9. 9
    fish oil

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

  10. 10
    natural flavors

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

  11. 11
    sodium tripolyphosphate

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

  12. 12
    calcium carbonate

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

  13. 13
    choline chloride

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

  14. 14
    taurine

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

  15. 15
    carrageenan Flagged

    Seaweed-derived thickener. Some lab studies suggest gut inflammation, but the evidence in pets is mixed.

  16. 16
    citric acid

    Natural antioxidant preservative. Helps keep fats from going rancid.

  17. 17
    sodium carbonate

    pH buffer used in food processing. Functional, no quality signal.

  18. 18
    zinc oxide

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

  19. 19
    ferrous sulfate

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

  20. 20
    zinc proteinate

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

  21. 21
    copper sulfate

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

  22. 22
    manganous oxide

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

  23. 23
    sodium selenite Flagged

    Inorganic selenium. Effective at AAFCO levels, no documented safety concern in dogs despite what some pet food blogs claim. Selenium yeast is a marginal upgrade, not a necessity. See why →

  24. 24
    calcium iodate

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

  25. 25
    magnesium oxide

    Inorganic magnesium. Functional at AAFCO doses, less efficiently absorbed than chelated forms.
