Good Neutral Watch Flagged
  1. 1
    pork

    Real meat. Dense protein and fat, though less common in dog food than chicken or beef.

  2. 2
    pork meal

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

  3. 3
    peas

    Cheap protein bulk. Fine in small amounts, but when peas stack with lentils and chickpeas in the top ingredients, it's the pattern the FDA flagged in its heart-disease investigation. See why →

  4. 4
    pea flour

    Powdered peas, usually used as a binder or filler. Counts toward the legume stack the FDA flagged.

  5. 5
    chickpeas

    Also called garbanzo beans. Affordable plant protein source, part of the legume stack the FDA examined in its heart-disease investigation. See why →

  6. 6
    pork fat

    Real animal fat from a named species. Clean energy source.

  7. 7
    flaxseed

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

  8. 8
    natural flavor

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

  9. 9
    choline chloride

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

  10. 10
    salt

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