In plain English

SPORTMiX Premium Stamina 24/18 Adult Dry Dog Food is a dry formula for adult dogs, with an unnamed meat meal as its first ingredient.

The formula is designed for adult maintenance, and while an AAFCO statement isn't published by the retailer, it's inferred to meet those nutritional standards. This is a basic requirement for dog food.

The primary protein is listed simply as 'meat meal,' which means its source isn't specified, and this type of ingredient often provides limited bioavailable amino acids. This contributes to a low protein quality score.

Good fit for adult dogs where budget is the primary concern. Less ideal if you prioritize specific, high-quality protein sources for your dog.

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

Who this is for

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. Good fit for adult Labrador Retrievers and similar active sporting breeds navigating weight management. Caloric density is not declared, with crude fiber at 5.5% (above the catalog median, supports satiety). 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) .

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 If you find a citation that's wrong, outdated, or misapplied, tell us.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

At 42/100, this formula sits below where we look for everyday picks. The lift comes from AAFCO compliance, worth 4 points to the final number: AAFCO formulation inferred from declared adult maintenance. Verbatim statement not published by retailer. The ceiling on this score is 54, set because the primary protein source is unnamed (e.g., 'meat meal' or 'animal by-product meal') rather than a named species. The cap isn't the binding constraint here. Protein quality would also need to improve to reach the next band.

What lifted the score

What pulled it down

Score capped at 54 due to primary protein is unnamed.

CAP why?

Good Neutral Watch Flagged
  1. 1
    meat meal

    Unnamed mammalian protein. No way to know what animal it came from. Avoid in favor of named meals.

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

  2. 2
    wheat

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

    Position 2: major carbohydrate source.

  3. 3
    yellow corn

    Position 3: major carbohydrate source.

  4. 4
    chicken fat

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

    Position 4: secondary fat. Often where marine oils sit when present alongside a primary land-animal fat.

  5. 5
    rice

    Generic rice. Could be white or brown, the label doesn't say. Brown rice would be specified if it were.

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

  6. 6
    corn germ meal

    Position 6: supporting grain. Smaller contribution to the carb deck.

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

  8. 8
    flaxseed

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

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

  9. 9
    chicken by-product meal

    Ground organs, bone, and tissue. Nutritionally dense, especially the liver and gizzard fractions. Named species ('chicken') is what matters. Generic 'poultry by-product meal' is the one to worry about. See why →

    Position 9: supporting protein. Modest contribution to total protein weight.

  10. 10
    potassium chloride

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

  11. 11
    choline chloride

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

  12. 12
    dl-methionine

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

  13. 13
    vitamin e supplement

    Required nutrient and a natural antioxidant. Often pulls double duty as a preservative.

  14. 14
    niacin supplement

    B vitamin (B3). Required in complete dog foods, added as a supplement to standardize the dose.

  15. 15
    calcium pantothenate

    Same as d-calcium pantothenate. Vitamin B5 in standardized form.

  16. 16
    vitamin a supplement

    Vitamin A in stable, standardized form. Required for vision, immune function, and growth.

  17. 17
    riboflavin supplement

    B vitamin (B2). Required in complete dog foods. The standardized form ensures consistent dosing.

  18. 18
    thiamine mononitrate

    B vitamin (B1). Essential for nervous system function. Cooked-in vitamin loss is why thiamine is always added back.

  19. 19
    pyridoxine hydrochloride

    B vitamin (B6). Essential for protein metabolism. Standard inclusion in complete formulas.

  20. 20
    biotin

    B vitamin that supports skin and coat health. Required for AAFCO-complete formulas.

  21. 21
    vitamin b12 supplement

    Essential for red blood cell formation and neurological function. Plant ingredients lack B12, so it has to be added.

  22. 22
    vitamin d3 supplement

    The active form of vitamin D dogs need. Required for calcium absorption and bone health.

  23. 23
    folic acid

    B vitamin (B9), essential for cell function. Standard in complete dog foods.
