FQI

AAFCO feeding trial substantiation for not stated.

ACF

Premium micronutrient forms such as chelated minerals or natural vitamin E.

MNI

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.

Good Neutral Watch Flagged
  1. 1
    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.

  2. 2
    pea fiber

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

  3. 3
    corn gluten meal

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

  4. 4
    wheat gluten

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

  5. 5
    powdered cellulose

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

  6. 6
    tapioca

    Starch from cassava root. Highly digestible energy source, but pure starch with minimal nutrition beyond that.

  7. 7
    wheat

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

  8. 8
    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.

  9. 9
    dried chicory root

    Natural prebiotic. Feeds beneficial gut bacteria. The same compound (inulin) used in human gut-health products.

  10. 10
    natural flavors

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

  11. 11
    chicken fat

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

  12. 12
    salt

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

  13. 13
    fish oil

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

  14. 14
    psyllium seed husk

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

  15. 15
    potassium chloride

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

  16. 16
    monocalcium phosphate

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

  17. 17
    vegetable oil

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

  18. 18
    dl-methionine

    Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.

  19. 19
    l-lysine

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

  20. 20
    fructooligosaccharides

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

  21. 21
    choline chloride

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

  22. 22
    calcium sulfate

    Source of calcium. Functional, required for AAFCO-complete formulas.

  23. 23
    taurine

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

  24. 24
    n-butyric acid
  25. 25
    calcium carbonate

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