In plain English

SPORTMiX Bite Size Adult Dry Dog Food is a dry formula for adult dogs, with yellow corn as its primary ingredient.

The formula is inferred to meet AAFCO standards for adult maintenance, meaning it's designed to be nutritionally complete. This is a basic requirement for commercial dog food.

The formula is heavily reliant on plant-based proteins, with yellow corn as the first ingredient. This means the primary protein source is not animal-based.

Good fit for adult dogs. Less ideal if you prefer a formula with an animal-based protein as the first ingredient.

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

Who this is for

Strong fit for active large sporting breeds like Labrador Retrievers, Golden Retrievers, and English Setters navigating weight management. At 315 kcal/cup this formula runs on the lean side, with crude fiber at 5% (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. 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) .

Why this score

Sniff scored this formula 36/100, landing in D-tier territory. The biggest contributor was AAFCO compliance (+4 points): AAFCO formulation inferred from declared adult maintenance. Verbatim statement not published by retailer. The biggest detractor was protein quality (-22 points): Plant-protein-dominated formula. yellow corn as the #1 ingredient. To reach C-tier, this formula would need to gain about 9 points, most likely through protein quality.

Good Neutral Watch Flagged
  1. 1
    yellow corn

    Position 1 grain: primary carbohydrate base. This is a grain-inclusive formula with yellow corn as the dominant carb.

  2. 2
    meat meal

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

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

  3. 3
    ground wheat

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

    Position 3: major carbohydrate source.

  4. 4
    soybean meal

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

    Position 4: plant protein in the top 5. Stacked with animal protein, can inflate the crude protein number without matching the amino-acid quality of named animal sources.

  5. 5
    chicken fat

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

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

  6. 6
    salt

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

  7. 7
    vitamin a supplement

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

  8. 8
    vitamin d3 supplement

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

  9. 9
    vitamin e supplement

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

  10. 10
    riboflavin supplement

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

  11. 11
    d-calcium pantothenate

    B vitamin (B5). Standard inclusion in complete dog foods.

  12. 12
    niacin supplement

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

  13. 13
    choline chloride

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

  14. 14
    vitamin b12 supplement

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

  15. 15
    folic acid

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

  16. 16
    thiamine mononitrate

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

  17. 17
    pyridoxine hydrochloride

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

  18. 18
    biotin

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

  19. 19
    calcium iodate

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

  20. 20
    copper sulfate

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

  21. 21
    ferrous sulfate

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

  22. 22
    manganous oxide

    Inorganic manganese. Functional, cheaper than chelated forms, less efficiently absorbed.

  23. 23
    zinc oxide

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

  24. 24
    magnesium oxide

    Inorganic magnesium. Functional at AAFCO doses, less efficiently absorbed than chelated forms.
