60 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
    cracked pearled barley

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

  4. 4
    oatmeal

    Gentle on the stomach. Slow-release carbs and soluble fiber that supports stool quality.

  5. 5
    grain sorghum

    Same as sorghum. Whole grain with a low glycemic index. Gluten-free, well-tolerated.

  6. 6
    dried yeast

    Natural source of B vitamins and trace minerals. Adds a savory flavor that dogs respond well to.

  7. 7
    rice

    Generic rice. Could be white or brown, the label doesn't say. Brown rice would be specified if it were.

  8. 8
    egg product

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

  9. 9
    chicken fat

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

  10. 10
    dried plain beet pulp

    Beet fiber, with the sugar removed. Long unfairly maligned. It's a real soluble fiber that supports stool quality.

  11. 11
    natural flavor

    Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.

  12. 12
    flaxseed

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

  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
    dl-methionine

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

  16. 16
    choline chloride

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

  17. 17
    taurine

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

  18. 18
    glucosamine hydrochloride

    Joint-support compound. Most useful in larger doses for older dogs. The kibble dose is real but modest.

  19. 19
    dried chicory root

    Natural prebiotic. Feeds beneficial gut bacteria. The same compound (inulin) used in human gut-health products.

  20. 20
    l-carnitine

    Amino acid derivative that helps the body convert fat into energy. Common in weight-management formulas.

  21. 21
    kale

    Leafy green with antioxidants and fiber. Small dose in kibble, but it's not just for marketing.

  22. 22
    chia seed

    Plant source of omega-3 and fiber. Like flaxseed, useful in trace amounts.

  23. 23
    pumpkin

    Soluble fiber that supports stool quality. Mild and well-tolerated.

  24. 24
    blueberries

    Antioxidants, real. But the amount in any kibble is too small to do much. Mostly marketing.

  25. 25
    oranges

Showing first 25 of 60. Position 1-5 has the largest weight in the recipe.

24 of 25 ingredients have a curated note. Coverage grows over time.
