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.

31 total
Good Neutral Watch Flagged
  1. 1
    lamb meal

    Lamb cooked down to a dry concentrate. Per pound, more protein than fresh lamb.

  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
    wheat

    Whole wheat. Fine for most dogs, though a portion are sensitive. Not a quality concern, just a fit-for-your-dog question.

  5. 5
    corn protein meal

    Concentrated corn protein. Similar in role to corn gluten meal, pads the protein number on the label without matching meat amino acids.

  6. 6
    whole grain corn

    Whole corn with the kernel intact. Decent fiber and B vitamins, though it can crowd out meat in cheaper recipes.

  7. 7
    chicken fat

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

  8. 8
    cracked pearled barley

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

  9. 9
    hydrolyzed chicken flavor

    Hydrolyzed chicken used as a palatability enhancer. Real ingredient, tiny inclusion, no quality signal either way.

  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
    potassium chloride

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

  15. 15
    pork liver flavor

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

  16. 16
    salt

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

  17. 17
    oats

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

  18. 18
    l-lysine

    Essential amino acid. Plant-protein-heavy formulas sometimes add it to round out the amino acid profile.

  19. 19
    fructooligosaccharides

    Prebiotic fiber, often called FOS. Feeds beneficial gut bacteria, similar in function to inulin.

  20. 20
    choline chloride

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

  21. 21
    calcium carbonate

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

  22. 22
    taurine

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

  23. 23
    ferrous sulfate

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

  24. 24
    zinc oxide

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

  25. 25
    copper sulfate

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