No declared omega-3 source. Fish oil, salmon oil, and algae oil all absent.

FQI

No AAFCO statement. Nutritional completeness unverified.

ACF

Controversial ingredients · 2

  • 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.
  • carrageenan
    Seaweed-derived thickener; some studies link it to gastrointestinal inflammation. Most common in wet foods but appears in some kibble gravies.

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

18 total
Good Neutral Watch Flagged
  1. 1
    beef

    Real meat. Dense in protein and iron. Some dogs are sensitive to it, but for most it's an excellent base.

  2. 2
    beef broth

    Real broth. Adds flavor and moisture, signals the recipe leans on real meat.

  3. 3
    chicken

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

  4. 4
    liver

    Generic liver, usually chicken or beef. Among the most nutrient-dense ingredients a dog can eat. Named species is more informative.

  5. 5
    pork lungs
  6. 6
    salmon

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

  7. 7
    potassium chloride

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

  8. 8
    zinc sulfate

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

  9. 9
    ferrous sulfate

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

  10. 10
    copper sulfate

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

  11. 11
    manganese sulfate

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

  12. 12
    potassium iodide

    Source of iodine, an essential trace mineral for thyroid function. Required for AAFCO-complete formulas.

  13. 13
    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 →

  14. 14
    carrageenan Flagged

    Seaweed-derived thickener. Some lab studies suggest gut inflammation, but the evidence in pets is mixed.

  15. 15
    guar gum

    Thickener common in wet food. Emerging research on emulsifiers and the gut microbiome, but no smoking gun in dogs yet.

  16. 16
    salt

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

  17. 17
    locust bean gum

    Thickener from carob seed. Generally well-tolerated. Less controversial than carrageenan or guar gum.

  18. 18
    choline chloride

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