Signature Stews Grain-Free Chicken, Duck & Pumpkin in Broth Wet Dog Food, 6-oz cup, case of 16
Graded by The Sniff System
Nulo Signature Stews Grain-Free Chicken, Duck & Pumpkin in Broth is a wet food featuring chicken and duck as its main protein sources.
This recipe includes quality fat sources like coconut oil, which also provides EPA and DHA. It also features quality carbohydrate sources with fermentable fiber, like pumpkin. The formula appears to be nutritionally complete, though an explicit AAFCO statement isn't published.
The formula contains menadione, a synthetic vitamin K3 banned in human supplements due to toxicity concerns. It also includes guar gum, an emulsifier with emerging microbiome data, though canine clinical evidence is lacking.
Good fit for dogs who enjoy a wet food with quality protein and fat. Less ideal if you prefer to avoid synthetic vitamin K3 or guar gum.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
In its 2022 update on diet-associated DCM, the FDA identified Golden Retrievers as the most reported breed, with 121 cases out of 1,382 total canine reports (8.8%) received between January 1, 2014, and November 1, 2022 (FDA, 2022) . Good fit for active large sporting breeds like Golden Retrievers, Labrador Retrievers, and Irish Setters navigating diet-associated DCM concerns. Chicken anchors position 1, with zero pulses in the top 15, plus added taurine at position 14.

At 53/100, this formula lands mid-pack. The lift comes from fat quality, worth 12 points to the final number: Quality fat sources: named fat with marine oil (EPA and DHA source). Where it lost ground: controversial-ingredient penalty, costing 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. The path to B-tier is about 7 points; controversial-ingredient penalty is the structural lever.

Controversial ingredients · 1
- menadioneSynthetic vitamin K3. Banned in human supplements due to toxicity concerns at high doses. Permitted in pet food but premium brands use natural vitamin K alternatives.
Every flagged ingredient has a published basis (confirmed harm / regulatory action / precautionary). See methodology →
Wet and fresh foods contain more water than kibble (typically 65-78%). On a dry-matter basis, this food's protein content is roughly 65%, comparable to premium kibble (typically 30-45% DMB protein).
Read why each ingredient is good or bad for dogs.
- 1protein animalchicken
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.
- 2chicken 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.
- 3protein animalduck
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.
- 4duck broth
Position 4: significant protein contributor. Adds amino-acid diversity to the top of the deck.
- 5vegetablepumpkin
Soluble fiber that supports stool quality. Mild and well-tolerated.
Position 5: meaningful whole-food inclusion. Source of vitamins, antioxidants, or natural fiber.
- 6fatcoconut 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.
- 7mineraltricalcium phosphate
Calcium and phosphorus source. Same role as dicalcium phosphate, slightly different ratio.
- 8mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 9fiberxanthan 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.
- 10mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 11fiberinulin
Prebiotic fiber that feeds beneficial gut bacteria. Same compound found in chicory root.
Position 11: trace fiber inclusion.
- 12fiberguar 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.
- 13supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 14supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 15fatsalmon 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.
- 16mineralmagnesium sulfate
Source of magnesium, a required mineral. Standard inclusion in complete diets.
- 17supplementparsley
Real herb. Trace amount of vitamins K and C. The dose in kibble is small, mostly there for label appeal.
- 18iron amino acid chelate
Iron bound to amino acids for better absorption. Premium form versus inorganic iron sulfate.
- 19zinc amino acid chelate
Zinc bound to amino acids for better absorption. Same idea as zinc proteinate, the premium form of the mineral.
- 20vitaminvitamin e supplement
Required nutrient and a natural antioxidant. Often pulls double duty as a preservative.
- 21l-ascorbyl-2-polyphosphate
A stable form of vitamin C used in pet food. Provides antioxidant support and survives processing better than plain ascorbic acid.
- 22vitaminthiamine mononitrate
B vitamin (B1). Essential for nervous system function. Cooked-in vitamin loss is why thiamine is always added back.
- 23vitaminvitamin a supplement
Vitamin A in stable, standardized form. Required for vision, immune function, and growth.
- 24nicotinic acid
- 25manganese amino acid chelate
Manganese bound to amino acids for better absorption. The chelated form most premium brands use.
