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
    duck

    Real meat. Often used as a novel protein for dogs with sensitivities to chicken or beef.

  2. 2
    chicken

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

  3. 3
    chicken liver

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

  4. 4
    turkey broth

    Real broth from named meat. Adds flavor and moisture, signals a recipe that leans on real meat.

  5. 5
    potato

    Standard white potato. Steady carb source, common starch in grain-free recipes.

  6. 6
    flaxseed

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

  7. 7
    natural flavor

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

  8. 8
    guar gum

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

  9. 9
    s doline chloride
  10. 10
    carrageenan Flagged

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

  11. 11
    cassia gum

    Thickener common in wet food. Functional, no major concerns at typical inclusion.

  12. 12
    salt

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

  13. 13
    iron amino acid chelate

    Iron bound to amino acids for better absorption. Premium form versus inorganic iron sulfate.

  14. 14
    zinc amino acid chelate

    Zinc bound to amino acids for better absorption. Same idea as zinc proteinate, the premium form of the mineral.

  15. 15
    vitamin e sa mononitrate
  16. 16
    copper amino acid chelate

    Copper bound to amino acids for better absorption. Premium form versus copper sulfate.

  17. 17
    manganese amino acid chelate

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

  18. 18
    sodium selenite Flagged

    Inorganic selenium. Effective at AAFCO levels, no documented safety concern in dogs despite what some pet food blogs claim. Selenium yeast is a marginal upgrade, not a necessity. See why →

  19. 19
    v wamin b12 supplement
  20. 20
    riboflavin supplement

    B vitamin (B2). Required in complete dog foods. The standardized form ensures consistent dosing.

  21. 21
    pyridoxine hydrochloride (vitamin b6, b wamin d3 supplement
