Controversial ingredients · 1

  • 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 →

25 total
Good Neutral Watch Flagged
  1. 1
    salmon

    Real fish meat. Natural source of omega-3s, which kibble usually has to add back from oil.

  2. 2
    salmon meal

    Salmon cooked into a dry concentrate. Carries both protein and natural omega-3s in one ingredient.

  3. 3
    sweet potato

    Complex carb with fiber and beta-carotene. Gentle on the stomach.

  4. 4
    potato

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

  5. 5
    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 →

  6. 6
    canola oil

    Plant oil. Some omega-3 from the parent plant, though dogs absorb it less efficiently than fish-derived omega-3. Fine in moderation.

  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
    potato protein

    Concentrated potato protein. Like pea protein, it inflates the protein number without matching meat-quality amino acids.

  10. 10
    pea protein

    Concentrated plant protein. Inflates the protein number on the label without matching the amino acid quality of meat.

  11. 11
    miscanthus grass

    Perennial grass used as a fiber source. Replaces cellulose in some recipes. Functional but unremarkable.

  12. 12
    dried yeast

    Natural source of B vitamins and trace minerals. Adds a savory flavor that dogs respond well to.

  13. 13
    potassium chloride

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

  14. 14
    salt

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

  15. 15
    choline chloride

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

  16. 16
    zinc amino acid complex

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

  17. 17
    iron amino acid complex

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

  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
    manganese amino acid complex

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

  20. 20
    copper amino acid complex

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

  21. 21
    calcium iodate

    Source of iodine for thyroid function. Functional, required in complete formulas.

  22. 22
    dl-methionine

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

  23. 23
    sunflower oil

    Common plant oil. Useful in moderation for omega-6, though too much skews the omega ratio against the dog's favor.

  24. 24
    taurine

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

  25. 25
    mixed tocopherols for freshness. b286623
