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.

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

49 total
Good Neutral Watch Flagged
  1. 1
    duck

    Real meat. Often used as a novel protein for dogs with sensitivities to chicken or beef.

  2. 2
    turkey

    Real meat. Lean protein, good amino acid profile, often well-tolerated by dogs sensitive to chicken.

  3. 3
    turkey meal

    Turkey with the water cooked out. Per pound, packs more protein than fresh turkey.

  4. 4
    oat flour
  5. 5
    brown rice

    Whole grain that's easy to digest. Steady carb energy plus a little fiber.

  6. 6
    pork meal

    Pork cooked into a dry concentrate. Per pound, more protein than fresh pork.

  7. 7
    ground grain sorghum

    Same as sorghum. Whole grain with a low glycemic index. Gluten-free, well-tolerated.

  8. 8
    vegetable

    Unnamed vegetable. No way to know what species. Named vegetables are far more transparent.

  9. 9
    pearled barley

    Barley with the outer hull removed. Easy to digest, steady carb release.

  10. 10
    pumpkin

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

  11. 11
    pork fat

    Real animal fat from a named species. Clean energy source.

  12. 12
    natural flavor

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

  13. 13
    brewer's dried yeast
  14. 14
    dried plain beet pulp

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

  15. 15
    sunflower oil

    Common plant oil. Useful in moderation for omega-6, though too much skews the omega ratio against the dog's favor.

  16. 16
    menhaden fish oil

    Omega-3 from menhaden, a small oily fish. Same skin and coat support as salmon oil.

  17. 17
    zinc proteinate

    Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.

  18. 18
    ferrous sulfate

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

  19. 19
    zinc sulfate

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

  20. 20
    iron proteinate

    Iron bound to protein for better absorption. The premium form versus inorganic iron sulfate.

  21. 21
    copper sulfate

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

  22. 22
    copper proteinate

    Copper bound to protein for better absorption. Common in better-formulated diets.

  23. 23
    manganese sulfate

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

  24. 24
    manganese proteinate

    Manganese bound to protein for better absorption. The chelated form most premium brands use.

  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 →
