Why this score

Reasonable protein quality. salmon delivers solid amino acid coverage.

PQI

Includes egg, named fish, or organ meat for diverse high-bioavailability protein.

STACK

AAFCO formulation inferred from declared all life stages. Verbatim statement not published by retailer.

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.

56 total
Good Neutral Watch Flagged
  1. 1
    salmon

    Real fish meat. Natural source of omega-3s, which kibble usually has to add back from oil.

  2. 2
    fish meal

    Concentrated fish protein, usually whitefish, herring, or mackerel. Strong amino acid profile.

  3. 3
    potato

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

  4. 4
    lentils

    Same concern as peas. Affordable plant protein, but when they pile up in the top 5 ingredients, it's a flag. See why →

  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 flour

    Powdered peas, usually used as a binder or filler. Counts toward the legume stack the FDA flagged.

  7. 7
    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.

  8. 8
    dried yeast

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

  9. 9
    dried tomato pomace

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

  10. 10
    natural flavor

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

  11. 11
    flaxseed

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

  12. 12
    dicalcium phosphate

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

  13. 13
    salt

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

  14. 14
    potassium chloride

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

  15. 15
    dl-methionine

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

  16. 16
    choline chloride

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

  17. 17
    taurine

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

  18. 18
    dried chicory root

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

  19. 19
    l-carnitine

    Amino acid derivative that helps the body convert fat into energy. Common in weight-management formulas.

  20. 20
    kale

    Leafy green with antioxidants and fiber. Small dose in kibble, but it's not just for marketing.

  21. 21
    chia seed

    Plant source of omega-3 and fiber. Like flaxseed, useful in trace amounts.

  22. 22
    pumpkin

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

  23. 23
    blueberries

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

  24. 24
    oranges
  25. 25
    quinoa

    Pseudo-grain with a complete amino acid profile. Rare in dog food because it's expensive.
