32 total
Good Neutral Watch Flagged
  1. 1
    chicken meal

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

  2. 2
    cracked pearled barley

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

  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
    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
    sorghum

    Whole grain with a low glycemic index. Gluten-free, well-tolerated, decent fiber content.

  7. 7
    oats

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

  8. 8
    chicken fat

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

  9. 9
    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.

  10. 10
    soybean meal

    Concentrated soy protein. Cheap plant protein that pads the label number, common in budget formulas.

  11. 11
    chicken liver flavor

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

  12. 12
    soybean oil

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

  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
    flaxseed

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

  15. 15
    potassium chloride

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

  16. 16
    calcium carbonate

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

  17. 17
    salt

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

  18. 18
    fructooligosaccharides

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

  19. 19
    choline chloride

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

  20. 20
    dl-methionine

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

  21. 21
    l-lysine

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

  22. 22
    ferrous sulfate

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

  23. 23
    zinc oxide

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

  24. 24
    copper sulfate

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

  25. 25
    manganous oxide

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