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
    lamb meal

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

  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
    chickpeas

    Also called garbanzo beans. Affordable plant protein source, part of the legume stack the FDA examined in its heart-disease investigation. See why →

  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
    fava beans

    Less common pulse. Same concern as peas when stacked with other legumes.

  7. 7
    canola meal
  8. 8
    flaxseeds

    Plural form, same as flaxseed. Plant source of omega-3, helpful for skin and coat.

  9. 9
    beef meal

    Beef cooked down to a dry concentrate. More protein per pound than fresh beef.

  10. 10
    dried plain beet pulp

    Beet fiber, with the sugar removed. Long unfairly maligned. It's a real soluble fiber that supports stool quality.

  11. 11
    pea starch

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

  12. 12
    natural flavor

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

  13. 13
    salt

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

  14. 14
    pea protein

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

  15. 15
    potassium chloride

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

  16. 16
    dried tomato pomace

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

  17. 17
    fish oil

    Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.

  18. 18
    choline chloride

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

  19. 19
    l-threonine

    Essential amino acid. Sometimes added when plant proteins dominate, since threonine is naturally lower in plants than meat.

  20. 20
    dried seaweed meal
  21. 21
    taurine

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

  22. 22
    dl-methionine

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

  23. 23
    blueberries

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

  24. 24
    carrots

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

  25. 25
    cranberries

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