PQI

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

FQI

AAFCO feeding trial substantiation for growth.

CIP

Controversial ingredients · 2

  • carrageenan
    Seaweed-derived thickener; some studies link it to gastrointestinal inflammation. Most common in wet foods but appears in some kibble gravies.
  • 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 →

Good Neutral Watch Flagged
  1. 1
    water sufficient for processing

    The regulatory phrase for cooking water in wet food. Has no nutritional implication, just labeling formality.

  2. 2
    chicken liver

    Organ meat. Dense in protein, iron, vitamin A, and the B vitamins. Among the most nutrient-rich ingredients a dog can eat.

  3. 3
    chicken

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

  4. 4
    chicken by-products
  5. 5
    pork by-products

    Generic pork organs and tissue without species-specific traceability. Named by-products are more transparent.

  6. 6
    wheat gluten

    Concentrated wheat protein. Like other plant gluten meals, it pads the protein number on the label without contributing meat-quality amino acids.

  7. 7
    powdered cellulose

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

  8. 8
    modified corn starch
  9. 9
    pork plasma
  10. 10
    natural flavors

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

  11. 11
    vegetable oil

    Unnamed plant oil. Could be soy, canola, corn, or a blend. Named oils like sunflower or canola are more transparent.

  12. 12
    brewers rice flour
  13. 13
    fish oil

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

  14. 14
    hydrolyzed yeast

    Yeast broken down with enzymes. Strong palatant plus a real source of B vitamins and amino acids.

  15. 15
    calcium carbonate

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

  16. 16
    carrageenan Flagged

    Seaweed-derived thickener. Some lab studies suggest gut inflammation, but the evidence in pets is mixed.

  17. 17
    sodium tripolyphosphate

    Preservative and texture agent in wet food. Functional at small doses, not a major concern, but some brands avoid it.

  18. 18
    guar gum

    Thickener common in wet food. Emerging research on emulsifiers and the gut microbiome, but no smoking gun in dogs yet.

  19. 19
    potassium phosphate
  20. 20
    taurine

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

  21. 21
    choline chloride

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

  22. 22
    potassium chloride

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

  23. 23
    zinc proteinate

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

  24. 24
    zinc oxide

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

  25. 25
    ferrous sulfate

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