42 total
Good Neutral Watch Flagged
  1. 1
    potato

    Standard white potato. Steady carb source, common starch in grain-free recipes.

  2. 2
    egg product

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

  3. 3
    potato protein

    Concentrated potato protein. Like pea protein, it inflates the protein number without matching meat-quality amino acids.

  4. 4
    dried tomato pomace

    The fiber-rich byproduct of tomato processing. Sometimes flagged unfairly. It's a real fiber source, not a filler shortcut.

  5. 5
    chicken fat

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

  6. 6
    flaxseed

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

  7. 7
    natural flavor

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

  8. 8
    fish oil

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

  9. 9
    dicalcium phosphate

    Calcium and phosphorus combined. Required source of both minerals, especially in formulas without much bone content.

  10. 10
    calcium carbonate

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

  11. 11
    psyllium seed husk

    Soluble fiber. Supports stool quality. The same fiber humans use for digestive regularity.

  12. 12
    ginger

    Real spice. Some anti-nausea evidence in humans, but the dose in kibble is small. Mostly for flavor.

  13. 13
    dried chicory root

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

  14. 14
    dl-methionine

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

  15. 15
    choline chloride

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

  16. 16
    taurine

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

  17. 17
    dried lactobacillus plantarum fermentation product
  18. 18
    dried bacillus subtilis fermentation product
  19. 19
    dried lactobacillus acidophilus fermentation product

    A probiotic strain. Whether the dose is high enough to actually colonize is debated, but it's a real beneficial bacterium.

  20. 20
    dried enterococcus faecium fermentation product
  21. 21
    dried bifidobacterium animalis fermentation product
  22. 22
    vitamin e supplement

    Required nutrient and a natural antioxidant. Often pulls double duty as a preservative.

  23. 23
    iron proteinate

    Iron bound to protein for better absorption. The premium form versus inorganic iron sulfate.

  24. 24
    zinc proteinate

    Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.

  25. 25
    copper proteinate

    Copper bound to protein for better absorption. Common in better-formulated diets.
