STACK

Score capped at 59 due to no AAFCO statement.

CAP why?

No AAFCO statement. Nutritional completeness unverified.

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.

Good Neutral Watch Flagged
  1. 1
    chicken

    Real meat. Primary protein source, with the amino acid profile dogs actually evolved to eat.

  2. 2
    chicken meal

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

  3. 3
    sweet potato

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

  4. 4
    potato

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

  5. 5
    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 →

  6. 6
    pea protein

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

  7. 7
    pea fiber

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

  8. 8
    pea starch

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

  9. 9
    ocean fish meal
  10. 10
    animal plasma
  11. 11
    chicken fat

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

  12. 12
    natural flavor

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

  13. 13
    spray dried animal blood cells
  14. 14
    salt

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

  15. 15
    carrots

    Real vegetable. Fiber, beta-carotene, and a small amount of antioxidant value.

  16. 16
    dicalcium phosphate

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

  17. 17
    pumpkin

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

  18. 18
    green beans

    Real vegetable. Fiber and a small amount of vitamins. Often used in weight-management formulas because it bulks up a meal without adding calories.

  19. 19
    blueberries

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

  20. 20
    cranberries

    Often added with a urinary-tract-support marketing angle. Real cranberry compounds help in concentrate form, but kibble doses are small.

  21. 21
    choline chloride

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

  22. 22
    dl-methionine

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

  23. 23
    salmon oil

    Pure omega-3s. The thing skin-and-coat formulas are usually built around.

  24. 24
    zinc sulfate

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

  25. 25
    ferrous sulfate

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