Duck Limited Ingredient Formula Canned Dog Food, 13-oz, case of 12
Graded by The Sniff System
Zignature Duck Limited Ingredient Formula Canned Dog Food is a wet food built around duck as its primary protein.
There are no notable positives to highlight for this formula.
This formula lacks an AAFCO statement, which caps its score. The protein quality from duck is noted as low in bioavailable amino acids, and there's no declared source of omega-3s like fish or algae oil.
Hard to recommend for any dog due to the lack of an AAFCO statement.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Good fit for active large sporting breeds like Labrador Retrievers, Golden Retrievers, and English Setters navigating weight management. Caloric density is not declared. The landmark 14-year Purina Lifespan Study on 48 Labrador Retrievers demonstrated that dogs fed 25% fewer calories lived a median of 1.8 years longer and delayed the onset of chronic diseases. The 2014 AAHA Weight Management Guidelines define overweight as a Body Condition Score (BCS) of 6-7 on a 9-point scale. A score of 8 or 9 indicates obesity, representing 20-30% and >30% above ideal body weight, respectively (Brooks et al., 2014) .

Sniff scored this formula 39/100, landing in D-tier territory. A hard cap of 59 also applied because the AAFCO nutritional adequacy statement isn't disclosed on the retailer page (so our methodology can't verify the formula meets adult, growth, or all-life-stages standards). Even without the cap, the base component scores sit below the next band. The structural fix would need to address protein quality as well.
No positive drivers crossed our reporting threshold.
Low protein quality. duck delivers limited bioavailable amino acids.
No declared omega-3 source. Fish oil, salmon oil, and algae oil all absent.
- Lowest fat quality in Zignature's lineup (4/16)

Read why each ingredient is good or bad for dogs.
- 1protein animalduck
Real meat. Often used as a novel protein for dogs with sensitivities to chicken or beef.
Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 2duck broth
Position 2: co-primary protein. Two named animal proteins in the top 2 is a strong protein build.
- 3legumepeas
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 →
Position 3. Pulse-family ingredient this high in the deck is a notable build choice. When stacked with other pulses in the top 10, matches the formulation pattern the FDA flagged in its diet-associated DCM investigation.
- 4legumechickpeas
Also called garbanzo beans. Affordable plant protein source, part of the legume stack the FDA examined in its heart-disease investigation. See why →
Position 4. Within the FDA's top-5 DCM-pattern threshold. Especially notable if multiple pulses stack here.
- 5supplementalfalfa meal
Dried alfalfa. Real fiber and trace minerals. Functional plant ingredient.
- 6agar-agar
Seaweed-derived gel used as a thickener. Functional alternative to carrageenan, generally well-tolerated.
- 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.
- 9supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 10mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 11vitaminvitamin e supplement
Required nutrient and a natural antioxidant. Often pulls double duty as a preservative.

- 16vitaminvitamin d3 supplement
The active form of vitamin D dogs need. Required for calcium absorption and bone health.
- 17vitaminthiamine mononitrate
B vitamin (B1). Essential for nervous system function. Cooked-in vitamin loss is why thiamine is always added back.
- 18vitaminvitamin b12 supplement
Essential for red blood cell formation and neurological function. Plant ingredients lack B12, so it has to be added.
- 19vitaminpyridoxine hydrochloride
B vitamin (B6). Essential for protein metabolism. Standard inclusion in complete formulas.

B vitamin (B9), essential for cell function. Standard in complete dog foods.

Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 22mineralzinc proteinate
Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.
- 23mineraliron proteinate
Iron bound to protein for better absorption. The premium form versus inorganic iron sulfate.

Copper bound to protein for better absorption. Common in better-formulated diets.
