Why this score

Reasonable protein quality. chicken delivers solid amino acid coverage.

PQI

Quality fat sources: named fat with marine oil (EPA and DHA source).

FQI

Quality carbohydrate sources with fermentable fiber.

CQI

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 →

Good Neutral Watch Flagged
  1. 1
    chicken

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

  2. 2
    chicken by-product meal

    Ground organs, bone, and tissue. Nutritionally dense, especially the liver and gizzard fractions. Named species ('chicken') is what matters. Generic 'poultry by-product meal' is the one to worry about.

  3. 3
    grain sorghum

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

  4. 4
    wheat flour

    Refined wheat, usually used as a binder. Cheap, not harmful, not a nutrition contributor.

  5. 5
    egg product

    Processed whole eggs. Same nutritional profile as fresh eggs, just shelf-stable.

  6. 6
    chicken fat

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

  7. 7
    dried plain beet pulp

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

  8. 8
    fish meal

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

  9. 9
    dried yeast

    Natural source of B vitamins and trace minerals. Adds a savory flavor that dogs respond well to.

  10. 10
    natural flavor

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

  11. 11
    flaxseed

    Plant source of omega-3. Helpful for skin and coat, though dogs absorb omega-3 from fish more efficiently.

  12. 12
    salmon oil

    Pure omega-3s. The thing skin-and-coat formulas are usually built around.

  13. 13
    potassium chloride

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

  14. 14
    salt

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

  15. 15
    choline chloride

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

  16. 16
    dried lactobacillus plantarum fermentation product
  17. 17
    dried bacillus subtilis fermentation product
  18. 18
    dried lactobacillus acidophilus fermentation product

    A probiotic strain. Whether the dose is high enough to actually colonize is debated, but it's a real beneficial bacterium.

  19. 19
    dried enterococcus faecium fermentation product
  20. 20
    dried bifidobacterium animalis fermentation product
  21. 21
    vitamin e supplement

    Required nutrient and a natural antioxidant. Often pulls double duty as a preservative.

  22. 22
    iron proteinate

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

  23. 23
    zinc proteinate

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

  24. 24
    copper proteinate

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

  25. 25
    ferrous sulfate

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