In plain English

ACANA Singles Limited Ingredient Duck & Pear is a grain-free dry dog food with duck and duck liver as its primary proteins.

This food has a strong protein profile, with duck as the primary ingredient, which means good biological value for your dog. It also includes quality fat sources like duck fat and fish oil, providing beneficial EPA and DHA. The formula is backed by AAFCO feeding trial substantiation.

There's some legume stacking with chickpeas and lentils appearing in the top 15 ingredients. This is a pattern the FDA has flagged, but the duck liver in the top 10 helps mitigate this concern.

Good fit for adult dogs, especially those with sensitivities who might benefit from a limited ingredient diet. Less ideal if you're concerned about legume stacking.

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

Who this is for

Good fit for adult French Bulldogs navigating a sensitive stomach. Working in its favor: prebiotic fiber (chicory or FOS) for gut health. Duck leads at position 1, and a single-species protein design that makes trigger isolation easier. What we'd flag: multiple protein sources stacked (harder to isolate triggers). Frenchies have notoriously sensitive GI tracts plus a tendency toward obesity given their low activity needs. Limited-ingredient formulas with moderate calorie density tend to fit them well.

Research informing this analysis

Methodology

The Sniff System grades this product against 3 cited studies relevant to its profile. Each link opens the original source.

Every claim on Sniff traces to a source. If you find a citation that's wrong, outdated, or misapplied, tell us.

Why this score

Solid grade. 72/100 (B) reflects the structural fit of this formula against The Sniff System's eight scoring components. Protein quality did the heavy lifting (+21 points): Strong protein profile with duck as the primary ingredient, delivering high biological value. What we'd flag for vet discussion: controversial-ingredient penalty (-2 points). Contains high legume stacking. Multiple pulse-family ingredients in top 15. Mitigated by taurine supplementation or organ meat (natural taurine precursor) in top 10. A-tier is 3.0 points away. Trimming controversial-ingredient penalty is the most direct route.

What lifted the score

Ingredients

Read why each ingredient is good or bad for dogs.

38 total
Good Neutral Watch Flagged
  1. 1
    duck

    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.

  2. 2
    duck meal

    Duck cooked into a dry concentrate. Per pound, more protein than fresh duck.

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

  3. 3
    duck liver

    Position 3. Named organ meat this high is a strong build choice. Concentrated source of taurine, glutamine, and B-vitamins.

  4. 4
    sweet potato

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

    Position 4: meaningful whole-food inclusion. Source of vitamins, antioxidants, or natural fiber.

  5. 5
    chickpeas

    Also called garbanzo beans. Affordable plant protein source, part of the legume stack the FDA examined in its heart-disease investigation. See why →

    Position 5. Within the FDA's top-5 DCM-pattern threshold. Especially notable if multiple pulses stack here.

  6. 6
    duck fat

    Position 6: supporting protein. Modest contribution to total protein weight.

  7. 7
    lentils

    Same concern as peas. Affordable plant protein, but when they pile up in the top 5 ingredients, it's a flag. See why →

    Position 7. Moderate inclusion. Contributes carbohydrate and some plant protein.

  8. 8
    lentil fiber

    Position 8. Moderate inclusion. Contributes carbohydrate and some plant protein.

  9. 9
    pears
  10. 10
    fish oil

    Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.

    Position 10. Moderate marine-oil inclusion. Supplements EPA/DHA without being the primary fat.

  11. 11
    natural duck flavor

    Position 11: trace protein. Likely there for amino-acid diversity or label appeal more than nutritional weight.

  12. 12
    pumpkin

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

    Position 12: garnish-level inclusion. Marketing-prominent but minimal nutritional impact at this position.

  13. 13
    cranberries

    Often added with a urinary-tract-support marketing angle. Real cranberry compounds help in concentrate form, but kibble doses are small.

    Position 13: garnish-level inclusion. Marketing-prominent but minimal nutritional impact at this position.

  14. 14
    choline chloride

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

  15. 15
    salt

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

  16. 16
    taurine

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

  17. 17
    vitamin e supplement

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

  18. 18
    dried kelp

    Natural source of iodine and trace minerals. A common premium-brand inclusion.

  19. 19
    zinc proteinate

    Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.

  20. 20
    mixed tocopherols

    Natural vitamin E used to keep fats from going rancid. The good kind of preservative. See why →

  21. 21
    vitamin a acetate
  22. 22
    vitamin d3 supplement

    The active form of vitamin D dogs need. Required for calcium absorption and bone health.

  23. 23
    niacin supplement

    B vitamin (B3). Required in complete dog foods, added as a supplement to standardize the dose.

  24. 24
    thiamine mononitrate

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

  25. 25
    calcium pantothenate

    Same as d-calcium pantothenate. Vitamin B5 in standardized form.

Showing first 25 of 38. Position 1-5 has the largest weight in the recipe.
