Bison & Rice Dry Dog Food, 28-lb bag
Graded by The Sniff System
Ultimates Bison & Rice Dry Dog Food is a dry food featuring bison and beef as its main protein sources.
This formula includes quality carbohydrate sources like rice and brown rice, which also provide fermentable fiber to support digestion.
A significant concern is the lack of an AAFCO statement, meaning its nutritional completeness is unverified. Also, the formula contains multiple pea ingredients, a pattern flagged in relation to canine dilated cardiomyopathy (DCM).
Good fit for dogs whose owners prioritize quality carbohydrates and fiber. Less ideal if AAFCO verification or pea ingredients are a concern.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Strong fit for active large sporting breeds, including the Labrador Retriever, navigating weight management. At 325 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. 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) .

Sniff scored this formula 50/100, landing in C-tier (acceptable-with-notes). The biggest contributor was carbohydrate quality (+12 points): Quality carbohydrate sources with fermentable fiber. 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). Even without the cap, the base component scores sit below the next band. The structural fix would need to address AAFCO compliance as well.

- 1bison meal
Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 2grainrice
Generic rice. Could be white or brown, the label doesn't say. Brown rice would be specified if it were.
Position 2: major carbohydrate source.
- 3legumepeas
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.
- 4grainbrown rice
Whole grain that's easy to digest. Steady carb energy plus a little fiber.
Position 4: supporting grain. Smaller contribution to the carb deck.
- 5protein animalbeef meal
Beef cooked down to a dry concentrate. More protein per pound than fresh beef. See why →
Position 5: significant protein contributor. Adds amino-acid diversity to the top of the deck.
- 6pea starch
Refined starch from peas, mostly carbs after the protein is removed. Counts toward the legume stack the FDA examined.
Position 6. Moderate inclusion. Contributes carbohydrate and some plant protein.
- 7fatchicken 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.
- 8protein plantpea protein
Concentrated plant protein. Inflates the protein number on the label without matching the amino acid quality of meat.
Position 8. Moderate inclusion. Contributes carbohydrate and some plant protein.
- 9grainrice
Generic rice. Could be white or brown, the label doesn't say. Brown rice would be specified if it were.
Position 9: minor grain inclusion.
- 10fiberdried 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 →
Position 10: functional fiber for digestion or satiety.
- 11fatflaxseed
Plant source of omega-3. Helpful for skin and coat, though dogs absorb omega-3 from fish more efficiently.
Position 11: trace fat. Below the level that materially shifts the fat profile.
- 12supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 13mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 14mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 15supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 16vitaminvitamin e supplement
Required nutrient and a natural antioxidant. Often pulls double duty as a preservative.
- 17vitaminniacin supplement
B vitamin (B3). Required in complete dog foods, added as a supplement to standardize the dose.
- 18vitamincalcium pantothenate
Same as d-calcium pantothenate. Vitamin B5 in standardized form.
- 19vitaminvitamin a supplement
Vitamin A in stable, standardized form. Required for vision, immune function, and growth.
- 20vitaminriboflavin supplement
B vitamin (B2). Required in complete dog foods. The standardized form ensures consistent dosing.
- 21vitaminthiamine mononitrate
B vitamin (B1). Essential for nervous system function. Cooked-in vitamin loss is why thiamine is always added back.
- 22vitaminpyridoxine hydrochloride
B vitamin (B6). Essential for protein metabolism. Standard inclusion in complete formulas.
- 23vitaminbiotin
B vitamin that supports skin and coat health. Required for AAFCO-complete formulas.
- 24vitaminvitamin b12 supplement
Essential for red blood cell formation and neurological function. Plant ingredients lack B12, so it has to be added.
- 25vitaminvitamin d3 supplement
The active form of vitamin D dogs need. Required for calcium absorption and bone health.
