Why this score

Strong protein profile with chicken as the primary ingredient, delivering high biological value.

PQI

Quality carbohydrate sources with declared fiber.

CQI

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

FQI

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 →

35 total
Good Neutral Watch Flagged
  1. 1
    chicken

    Real meat. Primary protein source, with the amino acid profile dogs actually evolved to eat.

  2. 2
    brown rice

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

  3. 3
    chicken meal

    Chicken with the water cooked out. Per pound, packs more protein than fresh chicken.

  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
    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
    pea fiber

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

  7. 7
    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.

  8. 8
    whole grain corn

    Whole corn with the kernel intact. Decent fiber and B vitamins, though it can crowd out meat in cheaper recipes.

  9. 9
    dried tomato pomace

    The fiber-rich byproduct of tomato processing. Sometimes flagged unfairly. It's a real fiber source, not a filler shortcut.

  10. 10
    soybean meal

    Concentrated soy protein. Cheap plant protein that pads the label number, common in budget formulas.

  11. 11
    soybean oil

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

  12. 12
    hydrolyzed chicken flavor

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

  13. 13
    coconut oil

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

  14. 14
    fish oil

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

  15. 15
    flaxseed

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

  16. 16
    lactic acid

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

  17. 17
    pork liver flavor

    Hydrolyzed pork liver used as a flavor enhancer. Same role as chicken liver flavor.

  18. 18
    l-lysine

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

  19. 19
    potassium chloride

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

  20. 20
    carrots

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

  21. 21
    salt

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

  22. 22
    dl-methionine

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

  23. 23
    choline chloride

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

  24. 24
    taurine

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

  25. 25
    ferrous sulfate

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