Why this score

Strong protein profile with deboned chicken as the primary ingredient, delivering high biological value.

PQI

Named fresh meat paired with same-species meal, a strong extrusion architecture.

STACK

AAFCO formulation inferred from declared adult maintenance. Verbatim statement not published by retailer.

ACF

Contains menadione. Banned for human OTC use but tolerated at AAFCO-permitted levels in pet food. The only AAFCO-permitted vitamin K source..

CIP

Controversial ingredients · 2

  • 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.
  • menadione
    Synthetic vitamin K3. Banned in human supplements due to toxicity concerns at high doses. Permitted in pet food but premium brands use natural vitamin K alternatives.

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

36 total
Good Neutral Watch Flagged
  1. 1
    deboned chicken

    Real meat with the bones removed before grinding. The cleanest version of chicken on an ingredient label.

  2. 2
    chicken meal

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

  3. 3
    turkey meal

    Turkey with the water cooked out. Per pound, packs more protein than fresh turkey.

  4. 4
    sweet potato

    Complex carb with fiber and beta-carotene. Gentle on the stomach.

  5. 5
    potato

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

  6. 6
    peas

    Cheap protein bulk. Fine in small amounts, but when peas stack with lentils and chickpeas in the top ingredients, it's the pattern the FDA flagged in its heart-disease investigation. See why →

  7. 7
    chicken fat

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

  8. 8
    natural flavor

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

  9. 9
    flaxseed

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

  10. 10
    dried yeast

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

  11. 11
    potassium chloride

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

  12. 12
    salt

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

  13. 13
    choline chloride

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

  14. 14
    apples

    Real fruit, some fiber and antioxidants. The amount in kibble is too small to matter much.

  15. 15
    blueberries

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

  16. 16
    zinc amino acid complex

    Zinc bound to amino acids for better absorption. Same idea as zinc proteinate, the premium form of the mineral.

  17. 17
    iron amino acid complex

    Iron bound to amino acids for better absorption. Premium form versus inorganic iron sulfate.

  18. 18
    sodium selenite Flagged

    Inorganic selenium. Effective at AAFCO levels, no documented safety concern in dogs despite what some pet food blogs claim. Selenium yeast is a marginal upgrade, not a necessity. See why →

  19. 19
    manganese amino acid complex

    Manganese bound to amino acids for better absorption. The chelated form most premium brands use.

  20. 20
    copper amino acid complex

    Copper bound to amino acids for better absorption. Premium form versus copper sulfate.

  21. 21
    calcium iodate

    Source of iodine for thyroid function. Functional, required in complete formulas.

  22. 22
    dl methionine
  23. 23
    taurine

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

  24. 24
    vitamin e supplement

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

  25. 25
    vitamin b12 supplement

    Essential for red blood cell formation and neurological function. Plant ingredients lack B12, so it has to be added.
