Good Neutral Watch Flagged
  1. 1
    chicken

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

  2. 2
    cracked pearled barley

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

  3. 3
    brown rice

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

  4. 4
    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.

  5. 5
    whole grain corn

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

  6. 6
    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.

  7. 7
    chicken fat

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

  8. 8
    chicken meal

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

  9. 9
    egg product

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

  10. 10
    chicken liver flavor

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

  11. 11
    pork liver flavor

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

  12. 12
    ground pecan shells
  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
    flaxseed

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

  16. 16
    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.

  17. 17
    calcium carbonate

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

  18. 18
    dried citrus pulp
  19. 19
    l-lysine

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

  20. 20
    choline chloride

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

  21. 21
    fish oil

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

  22. 22
    salt

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

  23. 23
    pressed cranberries
  24. 24
    l-threonine

    Essential amino acid. Sometimes added when plant proteins dominate, since threonine is naturally lower in plants than meat.

  25. 25
    l-tryptophan

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