In plain English

Hill's Science Diet Adult Perfect Digestion Salmon, Brown Rice & Whole Oats Recipe is a dry food for adult dogs, with salmon as its primary protein.

This formula offers good protein quality, with salmon providing solid amino acid coverage. It also includes quality carbohydrate sources that provide fermentable fiber, which is good for digestion. The fat sources are also high quality, being named and clearly declared.

Nothing concerning in the deck.

Good fit for adult dogs looking for a formula with quality protein, carbs, and fats. Nothing serious working against it.

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

Who this is for

Good fit for active large sporting breeds like Golden Retrievers, Labrador Retrievers, and Irish Setters navigating diet-associated DCM concerns. Salmon anchors position 1, with one pulse (pea protein at position 10), plus chicken liver flavor at position 11 (a natural taurine precursor). 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) .

Why this score

Sniff scored this formula 74/100, landing in B-tier territory. The biggest contributor was protein quality (+16 points): Reasonable protein quality. salmon delivers solid amino acid coverage. Also adding to the lift: carbohydrate quality (+15). Quality carbohydrate sources with fermentable fiber. The 1-point gap to A-tier sits mostly in protein quality (16 of 27 possible). Full protein quality requires named-species named-cut proteins in the top of the deck (e.g., "deboned chicken" rather than "chicken meal" or "poultry meal").

What lifted the score

Reasonable protein quality. salmon delivers solid amino acid coverage.

PQI

Quality carbohydrate sources with fermentable fiber.

CQI

Quality fat sources: named fat with declared fat sources.

FQI
What pulled it down

No negative drivers crossed our reporting threshold.

What sets this apart
  • Bottom 10% for DMB protein in dry kibbles (22.8%)
  • Top quartile for overall Sniff Score in Hill's Science Diet's lineup (74/100)

Ingredients

34 total
Good Neutral Watch Flagged
  1. 1
    salmon

    Real fish meat. Natural source of omega-3s, which kibble usually has to add back from oil.

    Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.

  2. 2
    cracked pearled barley

    Pre-cracked pearled barley for better digestibility. Same whole-grain story.

    Position 2. 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.

  3. 3
    brown rice

    Whole grain that's easy to digest. Steady carb energy plus a little fiber.

    Position 3: major carbohydrate source.

  4. 4
    brewers rice

    Broken rice kernels left over from milling, usually destined for human beer-making. Cheaper than whole or even white rice. Same carbs, less nutrition than the brown version. See why →

    Position 4: supporting grain. Smaller contribution to the carb deck.

  5. 5
    corn protein meal

    Concentrated corn protein. Similar in role to corn gluten meal, pads the protein number on the label without matching meat amino acids.

    Position 5: supporting grain. Smaller contribution to the carb deck.

  6. 6
    chicken meal

    Chicken with the water cooked out. Per pound, packs more protein than fresh chicken. See why →

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

  7. 7
    whole grain corn

    Whole corn with the kernel intact. Decent fiber and B vitamins, though it can crowd out meat in cheaper recipes.

    Position 7: supporting grain. Smaller contribution to the carb deck.

  8. 8
    chicken fat

    Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid. See why →

    Position 8: trace fat. Below the level that materially shifts the fat profile.

  9. 9
    oats

    Whole grain. Steady energy, soluble fiber, and well-tolerated by most dogs.

    Position 9: minor grain inclusion.

  10. 10
    pea protein

    Concentrated plant protein. Inflates the protein number on the label without matching the amino acid quality of meat.

    Position 10. Moderate inclusion. Contributes carbohydrate and some plant protein.

  11. 11
    chicken liver flavor

    Hydrolyzed chicken liver used as a flavor enhancer. Real ingredient, used in tiny amounts for palatability.

    Position 11. Small organ inclusion. Functional but not a primary contributor to the protein profile.

  12. 12
    ground pecan shells
  13. 13
    pork liver flavor

    Hydrolyzed pork liver used as a flavor enhancer. Same role as chicken liver flavor.

    Position 13. Small organ inclusion. Functional but not a primary contributor to the protein profile.

  14. 14
    lactic acid

    Natural acid used as a mild preservative and pH adjuster. Found in fermented foods too. Safe at typical inclusion.

  15. 15
    flaxseed

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

    Position 15: trace fat. Below the level that materially shifts the fat profile.

  16. 16
    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 →

  17. 17
    dried citrus pulp
  18. 18
    potassium chloride

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

  19. 19
    salt

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

  20. 20
    soybean oil

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

  21. 21
    choline chloride

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

  22. 22
    calcium carbonate

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

  23. 23
    pressed cranberries
  24. 24
    pumpkin

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

  25. 25
    taurine

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

Showing first 25 of 34. Position 1-5 has the largest weight in the recipe.
