Graded by The Sniff System

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. brewers rice 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 →

31 total
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
    hydrolyzed soy protein
  3. 3
    chicken fat

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

  4. 4
    natural flavors

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

  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
    vegetable oil

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

  7. 7
    sodium aluminosilicate

    Anti-caking agent that keeps powder ingredients flowing. Functional, not nutritional.

  8. 8
    calcium sulfate

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

  9. 9
    monocalcium phosphate

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

  10. 10
    fish oil

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

  11. 11
    potassium chloride

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

  12. 12
    calcium carbonate

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

  13. 13
    salt

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

  14. 14
    dl-methionine

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

  15. 15
    fructooligosaccharides

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

  16. 16
    choline chloride

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

  17. 17
    taurine

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

  18. 18
    gla safflower oil
  19. 19
    zinc proteinate

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

  20. 20
    zinc oxide

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

  21. 21
    manganese proteinate

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

  22. 22
    manganous oxide

    Inorganic manganese. Functional, cheaper than chelated forms, less efficiently absorbed.

  23. 23
    copper sulfate

    Inorganic copper. Standard, effective at small doses. Premium formulas tend to use copper proteinate instead.

  24. 24
    ferrous sulfate

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

  25. 25
    sodium selenite Flagged

    Inorganic selenium. Effective at AAFCO levels, no documented safety concern in dogs despite what some pet food blogs claim. Selenium yeast is a marginal upgrade, not a necessity. See why →
