Graded by The Sniff System

Why this score

Quality carbohydrate sources with fermentable fiber.

CQI

Reasonable protein quality. brown rice delivers solid amino acid coverage.

PQI

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

FQI

Score capped at 49 due to CP_DM=20.0%, CF_DM=16.7%.

CAP why?

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 →

34 total
Good Neutral Watch Flagged
  1. 1
    brown rice

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

  2. 2
    rice protein concentrate
  3. 3
    egg product

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

  4. 4
    soybean oil

    Plant oil. High in omega-6, which is required but commonly oversupplied. Fine in moderation.

  5. 5
    hydrolyzed chicken flavor

    Hydrolyzed chicken used as a palatability enhancer. Real ingredient, tiny inclusion, no quality signal either way.

  6. 6
    dried beet pulp

    Soluble fiber from sugar-beet processing. Sometimes treated as a filler, but it's actually one of the better fiber sources in kibble.

  7. 7
    coconut oil

    Saturated fat with medium-chain triglycerides. Mostly marketing in the doses kibble uses, but harmless.

  8. 8
    flaxseed

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

  9. 9
    fish oil

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

  10. 10
    dicalcium phosphate

    Calcium and phosphorus combined. Required source of both minerals, especially in formulas without much bone content.

  11. 11
    calcium carbonate

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

  12. 12
    lactic acid

    Natural acid used as a mild preservative and pH adjuster. Found in fermented foods too. Safe at typical inclusion.

  13. 13
    sodium tripolyphosphate

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

  14. 14
    potassium chloride

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

  15. 15
    l-lysine

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

  16. 16
    calcium sulfate

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

  17. 17
    l-threonine

    Essential amino acid. Sometimes added when plant proteins dominate, since threonine is naturally lower in plants than meat.

  18. 18
    choline chloride

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

  19. 19
    green peas

    Same as peas. Useful in small amounts. The concern is when pulses dominate the top of the ingredient list. See why →

  20. 20
    apples

    Real fruit, some fiber and antioxidants. The amount in kibble is too small to matter much.

  21. 21
    cranberries

    Often added with a urinary-tract-support marketing angle. Real cranberry compounds help in concentrate form, but kibble doses are small.

  22. 22
    salt

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

  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
    carrots

    Real vegetable. Fiber, beta-carotene, and a small amount of antioxidant value.

  25. 25
    ferrous sulfate

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