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 meal

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

  2. 2
    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 →

  3. 3
    tapioca

    Starch from cassava root. Highly digestible energy source, but pure starch with minimal nutrition beyond that.

  4. 4
    potato

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

  5. 5
    chicken fat

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

  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
    brewers dried yeast

    Yeast left over from brewing. Rich in B vitamins and amino acids. A traditional and well-tolerated inclusion.

  9. 9
    blueberries

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

  10. 10
    cranberries

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

  11. 11
    papaya
  12. 12
    mango
  13. 13
    apples

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

  14. 14
    basil
  15. 15
    oregano
  16. 16
    rosemary
  17. 17
    thyme
  18. 18
    sunflower seeds
  19. 19
    peppermint
  20. 20
    sodium chloride

    Same as salt. Required mineral, necessary at small doses.

  21. 21
    magnesium sulfate

    Source of magnesium, a required mineral. Standard inclusion in complete diets.

  22. 22
    buffered vinegar
  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
    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.
