CAP why?

Plant-protein-dominated formula. brown rice as the #1 ingredient.

PQI

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.

Every flagged ingredient has a published basis (confirmed harm / regulatory action / precautionary). See methodology →

Good Neutral Watch Flagged
  1. 1
    brown rice

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

  2. 2
    chicken fat

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

  3. 3
    egg product

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

  4. 4
    potato protein

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

  5. 5
    dried tomato pomace

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

  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
    menhaden fish oil

    Omega-3 from menhaden, a small oily fish. Same skin and coat support as salmon oil.

  9. 9
    calcium carbonate

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

  10. 10
    potassium citrate

    Source of potassium. Sometimes added in urinary-support formulas to help manage urine pH.

  11. 11
    dl-methionine

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

  12. 12
    choline chloride

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

  13. 13
    taurine

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

  14. 14
    dried chicory root

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

  15. 15
    dried lactobacillus plantarum fermentation product
  16. 16
    dried bacillus subtilis fermentation product
  17. 17
    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.

  18. 18
    dried enterococcus faecium fermentation product
  19. 19
    dried bifidobacterium animalis fermentation product
  20. 20
    vitamin e supplement

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

  21. 21
    iron proteinate

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

  22. 22
    zinc proteinate

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

  23. 23
    copper proteinate

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

  24. 24
    ferrous sulfate

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

  25. 25
    zinc sulfate

    Inorganic zinc. Effective at AAFCO doses but less well-absorbed than chelated forms like zinc proteinate.
