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 →

27 total
Good Neutral Watch Flagged
  1. 1
    chicken

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

  2. 2
    brown rice

    Whole grain that's easy to digest. Steady carb energy plus a little fiber.

  3. 3
    brewers rice

    Broken rice kernels left over from milling, usually destined for human beer-making. Cheaper than whole or even white rice. Same carbs, less nutrition than the brown version.

  4. 4
    cracked pearled barley

    Pre-cracked pearled barley for better digestibility. Same whole-grain story.

  5. 5
    chicken meal

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

  6. 6
    oats

    Whole grain. Steady energy, soluble fiber, and well-tolerated by most dogs.

  7. 7
    chicken fat

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

  8. 8
    pea protein

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

  9. 9
    flaxseed

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

  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
    chicken liver flavor

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

  12. 12
    lactic acid

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

  13. 13
    potassium chloride

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

  14. 14
    salt

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

  15. 15
    choline chloride

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

  16. 16
    dl-methionine

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

  17. 17
    calcium carbonate

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

  18. 18
    ferrous sulfate

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

  19. 19
    zinc oxide

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

  20. 20
    copper sulfate

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

  21. 21
    manganous oxide

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

  22. 22
    calcium iodate

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

  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
    taurine

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

  25. 25
    mixed tocopherols for freshness
