In plain English

Nulo Signature Stews Variety Pack is a grain-free wet food featuring chicken and duck, designed for small breeds.

This food features quality fat sources, including named fats with marine oil for EPA and DHA. It also provides quality carbohydrate sources with fermentable fiber, like pumpkin and inulin.

This recipe contains menadione, a synthetic vitamin K3 that's banned in human supplements due to toxicity concerns. It also includes guar gum, an emulsifier with emerging microbiome data, which is a minor penalty in canned foods.

Good fit for small breed dogs. Less ideal if you prefer foods without synthetic vitamin K3 or emulsifiers like guar gum.

Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.

Who this is for

Strong fit for adult Cavalier King Charles Spaniels and similar moderately active toy breeds navigating diet-associated DCM concerns. Chicken anchors position 1, with zero pulses in the top 15, plus added taurine at position 14. The FDA's 2019 investigation update on diet-associated DCM included 13 reported cases in Cavalier King Charles Spaniels, making them one of the top 15 most frequently reported breeds at that time  (FDA, 2019) .

Why this score

Sniff scored this formula 53/100, landing in C-tier (acceptable-with-notes). The biggest contributor was fat quality (+12 points): Quality fat sources: named fat with marine oil (EPA and DHA source). The biggest detractor was controversial-ingredient penalty (-5 points): Contains menadione. Banned for human OTC use but tolerated at AAFCO-permitted levels in pet food. The only AAFCO-permitted vitamin K source. To reach B-tier, this formula would need to gain about 7 points, most likely through controversial-ingredient penalty.

108 total
Good Neutral Watch Flagged
  1. 1
    chicken

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

    Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.

  2. 2
    chicken broth

    Real broth, adds flavor and moisture. Negligible nutrition on its own but tells you the recipe leans on real meat.

    Position 2: co-primary protein. Two named animal proteins in the top 2 is a strong protein build.

  3. 3
    duck

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

    Position 3: significant protein contributor. Adds amino-acid diversity to the top of the deck.

  4. 4
    duck broth

    Position 4: significant protein contributor. Adds amino-acid diversity to the top of the deck.

  5. 5
    pumpkin

    Soluble fiber that supports stool quality. Mild and well-tolerated.

    Position 5: meaningful whole-food inclusion. Source of vitamins, antioxidants, or natural fiber.

  6. 6
    coconut oil

    Saturated fat with medium-chain triglycerides. Mostly marketing in the doses kibble uses, but harmless.

    Position 6: secondary fat. Often where marine oils sit when present alongside a primary land-animal fat.

  7. 7
    tricalcium phosphate

    Calcium and phosphorus source. Same role as dicalcium phosphate, slightly different ratio.

  8. 8
    potassium chloride

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

  9. 9
    xanthan gum

    Thickener common in wet food and gravies. Same emulsifier-microbiome conversation as guar gum, not a clear flag. See why →

    Position 9: functional fiber for digestion or satiety.

  10. 10
    salt

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

  11. 11
    inulin

    Prebiotic fiber that feeds beneficial gut bacteria. Same compound found in chicory root.

    Position 11: trace fiber inclusion.

  12. 12
    guar gum

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

    Position 12: trace fiber inclusion.

  13. 13
    choline chloride

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

  14. 14
    taurine

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

  15. 15
    salmon oil

    Pure omega-3s. The thing skin-and-coat formulas are usually built around.

    Position 15. Trace marine oil. Contributes some omega-3 but well below the level that drives EPA/DHA totals.

  16. 16
    magnesium sulfate

    Source of magnesium, a required mineral. Standard inclusion in complete diets.

  17. 17
    parsley

    Real herb. Trace amount of vitamins K and C. The dose in kibble is small, mostly there for label appeal.

  18. 18
    iron amino acid chelate

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

  19. 19
    zinc amino acid chelate

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

  20. 20
    vitamin e supplement

    Required nutrient and a natural antioxidant. Often pulls double duty as a preservative.

  21. 21
    l-carnitine

    Amino acid derivative that helps the body convert fat into energy. Common in weight-management formulas.

  22. 22
    l-ascorbyl-2-polyphosphate

    A stable form of vitamin C used in pet food. Provides antioxidant support and survives processing better than plain ascorbic acid.

  23. 23
    thiamine mononitrate

    B vitamin (B1). Essential for nervous system function. Cooked-in vitamin loss is why thiamine is always added back.

  24. 24
    vitamin a supplement

    Vitamin A in stable, standardized form. Required for vision, immune function, and growth.

  25. 25
    nicotinic acid

Showing first 25 of 108. Position 1-5 has the largest weight in the recipe.
