In plain English

Supreme Source Beef, Chicken Meal & Lentil Recipe Dry Dog Food is a dry food featuring beef and chicken as its main protein sources.

This dry food offers reasonable protein quality, with beef providing solid amino acid coverage. It also includes quality fat sources like named fat and marine oil, which is a good source of EPA and DHA. Plus, it uses premium micronutrient forms such as chelated minerals.

The biggest watch item is the lack of an AAFCO statement, which means its nutritional completeness is unverified. It also contains high legume stacking, with multiple pulse-family ingredients in the top 15.

Good fit for owners who prioritize beef and chicken as primary proteins. Less ideal if AAFCO verification is a must-have.

Who this is for

Good fit for adult Labrador Retrievers navigating weight management. At 390 kcal/cup this formula runs on the moderate side, with crude fiber at 7% (above the catalog median, supports satiety). The landmark 14-year Purina Lifespan Study on 48 Labrador Retrievers demonstrated that dogs fed 25% fewer calories lived a median of 1.8 years longer and delayed the onset of chronic diseases. According to the Association for Pet Obesity Prevention's 2023 survey, 59% of dogs in the United States were classified as overweight or obese by their veterinary healthcare professional, representing an estimated 55 million dogs  (APOP, 2023) .

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 If you find a citation that's wrong, outdated, or misapplied, tell us.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

Sniff scored this formula 59/100, landing in C-tier (acceptable-with-notes). The biggest contributor was protein quality (+17.5 points): Reasonable protein quality. beef delivers solid amino acid coverage. A hard cap of 59 also applied because the AAFCO nutritional adequacy statement isn't disclosed on the retailer page (so our methodology can't verify the formula meets adult, growth, or all-life-stages standards). If the brand publishing the AAFCO statement were on the label, the cap would lift and this formula could clear the B-band threshold (60).

What lifted the score

Reasonable protein quality. beef delivers solid amino acid coverage.

PQI

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

FQI

Premium micronutrient forms such as chelated minerals or natural vitamin E.

MNI
What pulled it down

Score capped at 59 due to no AAFCO statement.

CAP why?

No AAFCO statement. Nutritional completeness unverified.

ACF

Contains high legume stacking. Multiple pulse-family ingredients in top 15. Mitigated by taurine supplementation or organ meat (natural taurine precursor) in top 10..

CIP
What sets this apart
  • Bottom 3% for DMB fat in grain-free dry kibbles (11.1%)
  • Top quartile for crude fiber in grain-free dry kibbles (7.8% DMB)
  • Bottom 4% for carb quality in dry kibbles (8/16)

51 total
Good Neutral Watch Flagged
  1. 1
    beef

    Real meat. Dense in protein and iron. Some dogs are sensitive to it, but for most it's an excellent base.

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

  2. 2
    chicken meal

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

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

  3. 3
    peas

    Cheap protein bulk. Fine in small amounts, but when peas stack with lentils and chickpeas in the top ingredients, it's the pattern the FDA flagged in its heart-disease investigation. See why →

    Position 3. 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.

  4. 4
    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 4. Within the FDA's top-5 DCM-pattern threshold. Especially notable if multiple pulses stack here.

  5. 5
    faba beans
  6. 6
    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 6. Moderate inclusion. Contributes carbohydrate and some plant protein.

  7. 7
    chicken fat

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

    Position 7: trace fat. Below the level that materially shifts the fat profile.

  8. 8
    flaxseeds

    Plural form, same as flaxseed. Plant source of omega-3, helpful for skin and coat.

  9. 9
    dried plain beet pulp

    Beet fiber, with the sugar removed. Long unfairly maligned. It's a real soluble fiber that supports stool quality. See why →

    Position 9: functional fiber for digestion or satiety.

  10. 10
    pea starch

    Refined starch from peas, mostly carbs after the protein is removed. Counts toward the legume stack the FDA examined.

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

  11. 11
    suncured alfalfa meal

    Sun-dried alfalfa, preserving more of the natural vitamins than heat-dried versions.

  12. 12
    natural flavor

    Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.

  13. 13
    fish oil

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

    Position 13. Trace marine oil. Contributes some omega-3 but well below the level that drives EPA/DHA totals.

  14. 14
    salt

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

  15. 15
    monosodium phosphate

    Mineral source and preservative. Standard inclusion at small doses.

  16. 16
    pea fiber

    Insoluble fiber from peas. Doesn't carry the protein-inflation concern of pea protein. Mostly there for stool quality.

  17. 17
    dried seaweed meal
  18. 18
    dried chicory root

    Natural prebiotic. Feeds beneficial gut bacteria. The same compound (inulin) used in human gut-health products.

  19. 19
    taurine

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

  20. 20
    choline chloride

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

  21. 21
    l-threonine

    Essential amino acid. Sometimes added when plant proteins dominate, since threonine is naturally lower in plants than meat.

  22. 22
    blueberries

    Antioxidants, real. But the amount in any kibble is too small to do much. Mostly marketing.

  23. 23
    carrots

    Real vegetable. Fiber, beta-carotene, and a small amount of antioxidant value.

  24. 24
    cranberries

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

  25. 25
    spinach

    Leafy green. Some iron, vitamin K, and fiber. The dose in kibble is small but it's real food.

Showing first 25 of 51. Position 1-5 has the largest weight in the recipe.
