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
    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.

  4. 4
    corn protein meal

    Concentrated corn protein. Similar in role to corn gluten meal, pads the protein number on the label without matching meat amino acids.

  5. 5
    chicken fat

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

  6. 6
    brown rice

    Whole grain that's easy to digest. Steady carb energy plus a little fiber.

  7. 7
    brewers rice flour
  8. 8
    natural flavors

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

  9. 9
    dried plain beet pulp

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

  10. 10
    wheat gluten

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

  11. 11
    fish oil

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

  12. 12
    potassium chloride

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

  13. 13
    calcium carbonate

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

  14. 14
    fructooligosaccharides

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

  15. 15
    sodium tripolyphosphate

    Preservative and texture agent in wet food. Functional at small doses, not a major concern, but some brands avoid it.

  16. 16
    choline chloride

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

  17. 17
    dl-methionine

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

  18. 18
    salt

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

  19. 19
    l-lysine

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

  20. 20
    rosemary extract

    Natural preservative. Replaces synthetic ones like BHA and BHT.

  21. 21
    preserved with mixed tocopherols and citric 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
    manganese proteinate

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