Why this score

Quality carbohydrate sources with fermentable fiber.

CQI

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

FQI

AAFCO feeding trial substantiation for adult maintenance.

ACF

Plant-protein-dominated formula. corn as the #1 ingredient.

PQI

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
    corn

    Whole corn is more nutritious than it gets credit for, with decent amino acids and steady carbs. The bigger concern is when corn dominates the top of the ingredient list at the expense of named meat.

  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
    pea fiber

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

  4. 4
    corn gluten meal

    Concentrated corn protein. Inflates the protein percent on the label without matching meat-quality amino acids.

  5. 5
    wheat

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

  6. 6
    wheat gluten

    Concentrated wheat protein. Like other plant gluten meals, it pads the protein number on the label without contributing meat-quality amino acids.

  7. 7
    barley

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

  8. 8
    natural flavors

    Same as natural flavor. Usually hydrolyzed liver or broth, adds palatability.

  9. 9
    chicken fat

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

  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
    powdered cellulose

    Plant fiber, often from wood pulp. Cheap bulk filler. Not harmful, but a tell that the recipe is reaching for inexpensive bulk.

  12. 12
    fish oil

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

  13. 13
    salt

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

  14. 14
    vegetable oil

    Unnamed plant oil. Could be soy, canola, corn, or a blend. Named oils like sunflower or canola are more transparent.

  15. 15
    psyllium seed husk

    Soluble fiber. Supports stool quality. The same fiber humans use for digestive regularity.

  16. 16
    sodium silico aluminate

    Same role as sodium aluminosilicate. Anti-caking agent at trace inclusion.

  17. 17
    potassium chloride

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

  18. 18
    fructooligosaccharides

    Prebiotic fiber, often called FOS. Feeds beneficial gut bacteria, similar in function to inulin.

  19. 19
    calcium carbonate

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

  20. 20
    taurine

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

  21. 21
    choline chloride

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

  22. 22
    l-lysine

    Essential amino acid. Plant-protein-heavy formulas sometimes add it to round out the amino acid profile.

  23. 23
    glucosamine hydrochloride

    Joint-support compound. Most useful in larger doses for older dogs. The kibble dose is real but modest.

  24. 24
    zinc proteinate

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

  25. 25
    manganese proteinate

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