Good Neutral Watch Flagged
  1. 1
    whole grain corn

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

  2. 2
    wheat

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

  3. 3
    soybean mill run
  4. 4
    powdered cellulose

    Plant fiber, often from wood pulp. Cheap bulk filler. Not harmful, but a tell that the recipe is reaching for inexpensive bulk.

    Hydrolyzed chicken liver used as a flavor enhancer. Real ingredient, used in tiny amounts for palatability.

  6. 6
    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.

  7. 7
    soybean oil

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

  8. 8
    pork protein isolate
  9. 9
    egg product

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

  16. 16
