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
    brewers rice

    Broken rice kernels left over from milling, usually destined for human beer-making. Cheaper than whole or even white rice. Same carbs, less nutrition than the brown version.

  2. 2
    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.

  3. 3
    chicken fat

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

  4. 4
    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.

  5. 5
    dried plain beet pulp

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

  6. 6
    natural flavors

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

  7. 7
    wheat gluten

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

  8. 8
    fish oil

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

  9. 9
    vegetable oil

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

  10. 10
    calcium carbonate

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

  11. 11
    salt

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

  12. 12
    potassium chloride

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

  13. 13
    powdered psyllium seed husk
  14. 14
    sodium silico aluminate

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

  15. 15
    dl-methionine

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

  16. 16
    fructooligosaccharides

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

  17. 17
    l-lysine

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

  18. 18
    choline chloride

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

  19. 19
    taurine

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

  20. 20
    potassium citrate

    Source of potassium. Sometimes added in urinary-support formulas to help manage urine pH.

  21. 21
    n-butyric acid
  22. 22
    magnesium oxide

    Inorganic magnesium. Functional at AAFCO doses, less efficiently absorbed than chelated forms.

  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
    zinc oxide

    Inorganic zinc. Cheapest mineral form on the market. Functional but less bioavailable than chelated alternatives.

  25. 25
    ferrous sulfate

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