Controversial ingredients · 1

  • 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
    chicken

    Real meat. Primary protein source, with the amino acid profile dogs actually evolved to eat.

  2. 2
    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 →

  3. 3
    potato

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

  4. 4
    potato starch

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

  5. 5
    chicken meal

    Chicken with the water cooked out. Per pound, packs more protein than fresh chicken.

  6. 6
    chicken fat

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

  7. 7
    pea protein

    Concentrated plant protein. Inflates the protein number on the label without matching the amino acid quality of meat.

  8. 8
    chicken liver flavor

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

  9. 9
    egg product

    Processed whole eggs. Same nutritional profile as fresh eggs, just shelf-stable.

  10. 10
    dried beet pulp

    Soluble fiber from sugar-beet processing. Sometimes treated as a filler, but it's actually one of the better fiber sources in kibble.

  11. 11
    soybean oil

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

  12. 12
    flaxseed

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

  13. 13
    lactic acid

    Natural acid used as a mild preservative and pH adjuster. Found in fermented foods too. Safe at typical inclusion.

  14. 14
    powdered cellulose

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

  15. 15
    pork liver flavor

    Hydrolyzed pork liver used as a flavor enhancer. Same role as chicken liver flavor.

  16. 16
    calcium sulfate

    Source of calcium. Functional, required for AAFCO-complete formulas.

  17. 17
    salt

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

  18. 18
    choline chloride

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

  19. 19
    potassium chloride

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

  20. 20
    taurine

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

  21. 21
    ferrous sulfate

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

  22. 22
    zinc oxide

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

  23. 23
    copper sulfate

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

  24. 24
    manganous oxide

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

  25. 25
    calcium iodate

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