In plain English

Hill's Prescription Diet d/d Skin/Food Sensitivities Duck Formula Wet Dog Food is a wet food featuring duck and duck liver as its main protein sources.

It uses quality carbohydrate sources with declared fiber, which is a nice touch. The fat sources are also good, with named fats and marine oil providing EPA and DHA. The formula has AAFCO feeding trial substantiation, which is always a plus.

A significant watch item is the very low protein and fat content on a dry matter basis, which capped its overall score. The protein quality from duck is also considered low, delivering limited bioavailable amino acids.

Good fit for dogs with specific dietary sensitivities, likely under veterinary guidance. Less ideal if your dog needs higher protein or fat levels.

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

Who this is for

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. Duck anchors position 2, with zero pulses in the top 15, plus duck liver at position 4 (a natural taurine precursor).

Looking at this for adult Golden Retrievers or Golden Retrievers with diet-associated DCM concerns ? We are building dedicated pages for these combinations.

Why this score

At 49/100, this formula lands mid-pack. The lift comes from carbohydrate quality, worth 13 points to the final number: Quality carbohydrate sources with declared fiber. The ceiling on this score is 49, set because the guaranteed analysis falls below AAFCO's minimum nutrient profile. The fix path: a formula update that meets AAFCO minimums. That would lift the cap and put this formula above the B-band line at 60.

What lifted the score

Quality carbohydrate sources with declared fiber.

CQI

Quality fat sources: named fat with marine oil (EPA and DHA source).

FQI

AAFCO feeding trial substantiation for not stated.

ACF
What pulled it down

Score capped at 49 due to CP_DM=3.3%, CF_DM=2.8%.

CAP why?

Low protein quality. duck delivers limited bioavailable amino acids.

PQI
What sets this apart
  • Bottom 2% for crude fiber in grain-free wet foods (1.7% DMB)
  • Top quartile for carb quality in grain-free wet foods (13/16)
  • Bottom quartile for protein quality in Hill's Prescription Diet's lineup (9/27)

Ingredients

22 total
Good Neutral Watch Flagged
  1. 1
    water

    Just water. Counted on the label of any wet or fresh food. The number tells you the moisture content.

  2. 2
    duck

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

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

  3. 3
    potato

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

    Position 3: meaningful whole-food inclusion. Source of vitamins, antioxidants, or natural fiber.

  4. 4
    duck liver

    Position 4. Named organ meat this high is a strong build choice. Concentrated source of taurine, glutamine, and B-vitamins.

  5. 5
    potato starch

    Refined potato. Pure carb energy, low on other nutrition. Often used as a binder in grain-free recipes.

  6. 6
    soybean oil

    Plant oil. High in omega-6, which is required but commonly oversupplied. Fine in moderation.

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

  7. 7
    fish oil

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

    Position 7. Moderate marine-oil inclusion. Supplements EPA/DHA without being the primary fat.

  8. 8
    powdered cellulose

    Plant fiber, often from wood pulp. Cheap bulk filler. Not harmful, but a tell that the recipe is reaching for inexpensive bulk.

    Position 8: functional fiber for digestion or satiety.

  9. 9
    dicalcium phosphate

    Calcium and phosphorus combined. Required source of both minerals, especially in formulas without much bone content.

  10. 10
    calcium carbonate

    Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.

  11. 11
    salt

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

  12. 12
    dl-methionine

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

  13. 13
    potassium chloride

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

  14. 14
    choline chloride

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

  15. 15
    l-tryptophan

    Essential amino acid. Sometimes added in calming or weight-management formulas.

  16. 16
    zinc oxide

    Inorganic zinc. Cheapest mineral form on the market. Functional but less bioavailable than chelated alternatives.

  17. 17
    ferrous sulfate

    Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.

  18. 18
    manganese sulfate

    Inorganic manganese. Functional but less well-absorbed than the chelated proteinate form.

  19. 19
    copper sulfate

    Inorganic copper. Standard, effective at small doses. Premium formulas tend to use copper proteinate instead.

  20. 20
    calcium iodate

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

  21. 21
    taurine

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

  22. 22
    beta-carotene
