In plain English

Hill's Prescription Diet z/d Skin & Food Sensitivities is a wet food featuring hydrolyzed chicken liver, designed for dogs with sensitivities.

The protein quality is reasonable, with hydrolyzed chicken liver providing good amino acid coverage. It also includes quality fat sources like fish oil, which offers beneficial EPA and DHA. The formula has AAFCO feeding trial substantiation.

The main thing to note is that the score is capped due to the relatively low protein and fat content on a dry matter basis.

Good fit for dogs with skin or food sensitivities who need a hydrolyzed protein diet.

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, including the Golden Retriever, navigating diet-associated DCM concerns. Hydrolyzed chicken liver anchors position 2, with zero pulses in the top 15, plus hydrolyzed chicken liver at position 2 (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 47/100, this formula lands mid-pack. The lift comes from protein quality, worth 14 points to the final number: Reasonable protein quality. hydrolyzed chicken liver delivers solid amino acid coverage. 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.

  1. 1
    water

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

    hydrolyzed chicken liver
  3. 3
    corn starch

    Position 3: major carbohydrate source.

  4. 4
    ground pecan shells
  5. 5
    soybean oil

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

    Position 5: secondary fat. Often where marine oils sit when present alongside a primary land-animal fat.

  6. 6
    flaxseed

    Plant source of omega-3. Helpful for skin and coat, though dogs absorb omega-3 from fish more efficiently.

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

  7. 7
    dried beet pulp

    Soluble fiber from sugar-beet processing. Sometimes treated as a filler, but it's actually one of the better fiber sources in kibble. See why →

    Position 7: functional fiber for digestion or satiety.

  8. 8
    dried citrus pulp
  9. 9
    fish oil

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

    Position 9. Moderate marine-oil inclusion. Supplements EPA/DHA without being the primary fat.

  10. 10
    dicalcium phosphate

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

  11. 11
    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 11: trace fiber inclusion.

  12. 12
    coconut oil

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

    Position 12: trace fat. Below the level that materially shifts the fat profile.

  13. 13
    calcium carbonate

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

  14. 14
    pressed cranberries
  15. 15
    potassium chloride

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

  16. 16
    dl-methionine

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

  17. 17
    salt

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

  18. 18
    choline chloride

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

  19. 19
    potassium citrate

    Source of potassium. Sometimes added in urinary-support formulas to help manage urine pH.

  20. 20
    ferrous sulfate

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

  21. 21
    zinc oxide

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

  22. 22
    copper sulfate

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

  23. 23
    manganese sulfate

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

  24. 24
    calcium iodate

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

    l-tryptophan

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