FQI

Quality carbohydrate sources with declared fiber.

CQI

AAFCO feeding trial substantiation for adult maintenance.

ACF

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.

Every flagged ingredient has a published basis (confirmed harm / regulatory action / precautionary). See methodology →

31 total
Good Neutral Watch Flagged
  1. 1
    chicken

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

  2. 2
    rice

    Generic rice. Could be white or brown, the label doesn't say. Brown rice would be specified if it were.

  3. 3
    wheat

    Whole wheat. Fine for most dogs, though a portion are sensitive. Not a quality concern, just a fit-for-your-dog question.

  4. 4
    poultry by-product meal

    Unnamed poultry. The mix can include any combination of chicken, turkey, or other birds, with no traceability. Named by-product meals are fine. This one isn't.

  5. 5
    corn protein meal

    Concentrated corn protein. Similar in role to corn gluten meal, pads the protein number on the label without matching meat amino acids.

  6. 6
    oat meal

    Alternate spelling of oatmeal. Gentle whole grain, steady carb energy, soluble fiber.

  7. 7
    barley

    Whole grain with a low glycemic profile and some soluble fiber. Easy on blood sugar.

  8. 8
    pea fiber

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

  9. 9
    fish meal

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

  10. 10
    dried egg product

    Whole eggs with the water removed. Same nutritional value as fresh eggs, just shelf-stable.

  11. 11
    beef fat preserved with mixed-tocopherols

    Real animal fat from a named species, with natural vitamin E doing the preservation. The clean version.

  12. 12
    natural flavor

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

  13. 13
    wheat bran
  14. 14
    fish oil

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

  15. 15
    salt

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

  16. 16
    calcium carbonate

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

  17. 17
    mono and dicalcium phosphate

    Source of calcium and phosphorus. Standard inclusion in complete dog foods.

  18. 18
    potassium chloride

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

  19. 19
    potassium citrate

    Source of potassium. Sometimes added in urinary-support formulas to help manage urine pH.

  20. 20
    zinc sulfate

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

  21. 21
    ferrous sulfate

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

  22. 22
    manganese sulfate

    Inorganic manganese. Functional but less well-absorbed than the chelated proteinate form.

  23. 23
    copper sulfate

    Inorganic copper. Standard, effective at small doses. Premium formulas tend to use copper proteinate instead.

  24. 24
    calcium iodate

    Source of iodine for thyroid function. Functional, required in complete formulas.

  25. 25
    sodium selenite Flagged

    Inorganic selenium. Effective at AAFCO levels, no documented safety concern in dogs despite what some pet food blogs claim. Selenium yeast is a marginal upgrade, not a necessity. See why →
