Reasonable protein quality. chicken delivers solid amino acid coverage.

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.

Good Neutral Watch Flagged
  1. 1
    chicken

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

  2. 2
    rice

    Generic rice. Could be white or brown, the label doesn't say. Brown rice would be specified if it were.

  3. 3
    wheat

    Whole wheat. Fine for most dogs, though a portion are sensitive. Not a quality concern, just a fit-for-your-dog question.

  4. 4
    poultry by-product meal

    Unnamed poultry. The mix can include any combination of chicken, turkey, or other birds, with no traceability. Named by-product meals are fine. This one isn't.

  5. 5
    soybean meal

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

  6. 6
    whole grain corn

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

  7. 7
    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.

  8. 8
    beef fat preserved with mixed-tocopherols

    Real animal fat from a named species, with natural vitamin E doing the preservation. The clean version.

  9. 9
    barley

    Whole grain with a low glycemic profile and some soluble fiber. Easy on blood sugar.

  10. 10
    dried egg product

    Whole eggs with the water removed. Same nutritional value as fresh eggs, just shelf-stable.

  11. 11
    corn germ meal
  12. 12
    fish meal

    Concentrated fish protein, usually whitefish, herring, or mackerel. Strong amino acid profile.

  13. 13
    natural flavor

    Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.

  14. 14
    glycerin

    Humectant used in soft-moist foods to keep them chewy. Safe in moderation but a signal of a processed semi-moist product.

  15. 15
    fish oil

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

  16. 16
    calcium carbonate

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

  17. 17
    wheat bran
  18. 18
    soybean oil

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

  19. 19
    mono and dicalcium phosphate

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

  20. 20
    salt

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

  21. 21
    potassium citrate

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

  22. 22
    zinc proteinate

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

  23. 23
    ferrous sulfate

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

  24. 24
    manganese proteinate

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

  25. 25
    copper proteinate

    Copper bound to protein for better absorption. Common in better-formulated diets.
