Nothing concerning in the deck.

Good fit for large breed puppies. 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

Labs are the canonical food-motivated breed. Weight management is the dominant practical concern, even more than breed-specific health risks. Strong fit for active large sporting breeds like Labrador Retrievers, Golden Retrievers, and English Setters navigating weight management. Caloric density is not declared. 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) .

Looking at this for puppy Labrador Retrievers or Labrador Retrievers with weight management ? We are building dedicated pages for these combinations.

Auto-matched from this product's measurements (ingredients, life stage, calorie density) to a breed archetype. Not a substitute for vet input on your specific dog.

Research informing this analysis

Methodology

The Sniff System grades this product against 2 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 If you find a citation that's wrong, outdated, or misapplied, tell us.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

At 73/100, this formula lands in solid B territory. The lift comes from protein quality, worth 16 points to the final number: Reasonable protein quality. chicken delivers solid amino acid coverage. Secondary contribution comes from carbohydrate quality (+15 points). Quality carbohydrate sources with fermentable fiber. The 2-point gap to the A-tier line is concentrated 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. chicken delivers solid amino acid coverage.

PQI

Quality carbohydrate sources with fermentable fiber.

CQI

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

FQI
What pulled it down

No negative drivers crossed our reporting threshold.

What sets this apart
  • Bottom 4% for crude fiber in grain-inclusive dry kibbles (3.3% DMB)
  • Top quartile for DMB protein in Hill's Science Diet's lineup (26.7%)
  • Bottom quartile for DMB fat in grain-inclusive dry kibbles (12.2%)

Ingredients

39 total
Good Neutral Watch Flagged
  1. 1
    chicken

    Real meat. Primary protein source, with the amino acid profile dogs actually evolved to eat.

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

  2. 2
    brown rice

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

    Position 2: major carbohydrate source.

  3. 3
    oats

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

    Position 3: major carbohydrate source.

  4. 4
    chicken meal

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

    Position 4: significant protein contributor. Adds amino-acid diversity to the top of the deck.

  5. 5
    cracked pearled barley

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

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

  6. 6
    chicken fat

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

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

  7. 7
    pea protein

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

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

  8. 8
    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 8: supporting grain. Smaller contribution to the carb deck.

  9. 9
    wheat

    Whole wheat. Fine for most dogs, though a portion are sensitive. Not a quality concern, just a fit-for-your-dog question.

    Position 9: minor grain inclusion.

  10. 10
    soybean meal

    Concentrated soy protein. Cheap plant protein that pads the label number, common in budget formulas.

    Position 10: moderate plant-protein boost. Less likely to materially shift the protein profile.

  11. 11
    whole grain corn

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

    Position 11: minor grain inclusion.

  12. 12
    chicken liver flavor

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

    Position 12. Small organ inclusion. Functional but not a primary contributor to the protein profile.

  13. 13
    ground pecan shells
  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
    pork liver flavor

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

    Position 15. Small organ inclusion. Functional but not a primary contributor to the protein profile.

  16. 16
    dicalcium phosphate

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

  17. 17
    flaxseed

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

  18. 18
    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 →

  19. 19
    fish oil

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

  20. 20
    salt

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

  21. 21
    dried citrus pulp
  22. 22
    potassium chloride

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

  23. 23
    choline chloride

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

  24. 24
    pressed cranberries
  25. 25
    calcium carbonate

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

Showing first 25 of 39. Position 1-5 has the largest weight in the recipe.

22 of 25 ingredients have a curated note. Coverage grows over time.
