  • 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.

Ingredients

29 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
    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.

  3. 3
    soybean meal

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

  4. 4
    chicken fat

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

  5. 5
    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.

  6. 6
    pork meal

    Pork cooked into a dry concentrate. Per pound, more protein than fresh pork.

  7. 7
    wheat

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

  8. 8
    brown rice

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

  9. 9
    ground grain sorghum

    Same as sorghum. Whole grain with a low glycemic index. Gluten-free, well-tolerated.

  10. 10
    dried plain beet pulp

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

  11. 11
    natural flavors

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

  12. 12
    salt

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

  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
    choline chloride

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

  15. 15
    rosemary extract

    Natural preservative. Replaces synthetic ones like BHA and BHT.

  16. 16
    preserved with mixed tocopherols and citric acid
  17. 17
    potassium chloride

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

  18. 18
    fructooligosaccharides

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

  19. 19
    dl-methionine

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

  20. 20
    monocalcium phosphate

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

  21. 21
    calcium carbonate

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

  22. 22
    zinc oxide

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

  23. 23
    ferrous sulfate

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

  24. 24
    manganous oxide

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

  25. 25
    copper sulfate

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