STACK

Premium micronutrient forms such as chelated minerals or natural vitamin E.

MNI

Score capped at 59 due to no AAFCO statement.

CAP why?

No AAFCO statement. Nutritional completeness unverified.

ACF

Contains high legume stacking. Multiple pulse-family ingredients in top 15. Mitigated by taurine supplementation or organ meat (natural taurine precursor) in top 10..

CIP

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.

61 total
Good Neutral Watch Flagged
  1. 1
    lamb

    Real meat. Often used for dogs with chicken or beef sensitivities. Slightly higher fat content than chicken.

  2. 2
    lamb meal

    Lamb cooked down to a dry concentrate. Per pound, more protein than fresh lamb.

  3. 3
    potato

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

  4. 4
    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 →

  5. 5
    pea starch

    Refined starch from peas, mostly carbs after the protein is removed. Counts toward the legume stack the FDA examined.

  6. 6
    tapioca starch

    Refined cassava starch, used as a binder. Easy to digest, low on nutrition.

  7. 7
    pea protein

    Concentrated plant protein. Inflates the protein number on the label without matching the amino acid quality of meat.

  8. 8
    dried tomato pomace

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

  9. 9
    chicken fat

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

  10. 10
    flaxseed

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

  11. 11
    natural flavor

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

  12. 12
    dried yeast

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

  13. 13
    potato starch

    Refined potato. Pure carb energy, low on other nutrition. Often used as a binder in grain-free recipes.

  14. 14
    direct dehydrated alfalfa pellets

    Pelleted alfalfa with the moisture removed. Same role as alfalfa meal, fiber and minerals.

  15. 15
    canola oil

    Plant oil. Some omega-3 from the parent plant, though dogs absorb it less efficiently than fish-derived omega-3. Fine in moderation.

  16. 16
    dl-methionine

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

  17. 17
    salt

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

  18. 18
    dicalcium phosphate

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

  19. 19
    choline chloride

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

  20. 20
    dried chicory root

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

  21. 21
    pea fiber

    Insoluble fiber from peas. Doesn't carry the protein-inflation concern of pea protein. Mostly there for stool quality.

  22. 22
    alfalfa nutrient concentrate

    Concentrated alfalfa, rich in vitamins, minerals, and fiber. A legitimate functional ingredient.

  23. 23
    calcium carbonate

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

  24. 24
    potassium chloride

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

  25. 25
    taurine

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