The short answer: Effectively tie (A/93 vs A/92 — one point within rubric noise). Both are premium freeze-dried beef treats; the structural difference is single-ingredient simplicity vs multi-part WholePrey approach. Bowl Boosters Bare Beef is whole beef muscle meat plus three natural antioxidant preservatives. Carnivore Crunch is five named beef parts — muscle, liver, heart, kidney, and tripe — without added preservatives. The four organ meats deliver micronutrient breadth muscle meat alone cannot match; the single-ingredient simplicity delivers a cleaner ingredient label.

The scores

Wellness Bowl Boosters Bare Beef Single-Ingredient Freeze-Dried Beef Topper: A (93/100) — Beef, Mixed Tocopherols, Rosemary Extract, Green Tea Extract.

Stella & Chewy's Carnivore Crunch Grass-Fed Beef Recipe Freeze-Dried Dog Treats: A (92/100) — Beef, Beef Liver, Beef Heart, Beef Kidney, Beef Tripe.

How the ingredients compare

The top-five ingredients reveal the formulation split between these two products:

Bowl Boosters Bare Beef: Beef, Mixed Tocopherols, Rosemary Extract, Green Tea Extract

Stella & Chewy's Carnivore Crunch: Beef, Beef Liver, Beef Heart, Beef Kidney, Beef Tripe

Both products earn effectively the same v15 score, but the ingredient lineups tell different stories about how they got there — that is where the actual pick decision lives.

Where Bowl Boosters Bare Beef pulls ahead

Single-ingredient simplicity: Bowl Boosters Bare Beef is exactly one named animal protein (beef) plus three natural preservatives. For owners managing dogs with multiple food sensitivities or doing elimination diets, single-ingredient treats minimize variable exposure. Carnivore Crunch’s five-part WholePrey approach is structurally richer but adds more variables to track. Shop on Amazon →

Lower vitamin A and copper risk: Carnivore Crunch contains beef liver and kidney — both concentrated in preformed vitamin A and copper. At high daily volumes in small dogs over long periods, these can push toward upper-limit concerns. Muscle-meat treats like Bowl Boosters have no equivalent risk and are safer for daily high-volume training treat use.

Three-layer natural antioxidant preservation: Mixed tocopherols + rosemary extract + green tea extract provide redundant fat-oxidation protection. Carnivore Crunch skips added preservatives entirely, accepting a shorter shelf-life.

Where Stella & Chewy's Carnivore Crunch holds its own

WholePrey-style organ-meat density: Five named beef parts (muscle + liver + heart + kidney + tripe) deliver a far broader micronutrient profile than muscle meat alone. Liver supplies vitamin A and B12; heart supplies CoQ10 and high-density taurine; kidney supplies selenium; tripe supplies natural digestive enzymes and probiotic-like beneficial bacteria. This is the WholePrey philosophy translated into treat format. Shop on Amazon →

Grass-fed beef sourcing: Carnivore Crunch specifies grass-fed beef — meaningfully different from feedlot conventional beef in omega-3-to-omega-6 ratio (grass-fed runs ~3x more favorable), CLA content (higher in grass-fed), and overall fat-profile composition. Bowl Boosters Bare Beef doesn’t specify grass-fed sourcing on the package.

No added preservatives: Pure beef with nothing else. For the cleanest possible ingredient label, Carnivore Crunch is structurally simpler in the preservative dimension.

The bottom line

Bowl Boosters Bare Beef and Stella & Chewy’s Carnivore Crunch are both A-tier freeze-dried beef treats with different structural philosophies. Bowl Boosters is the single-ingredient muscle-meat option — clean label, safe for daily high-volume training, three natural antioxidant preservatives. Carnivore Crunch is the WholePrey option — five named beef parts including four organ meats, grass-fed sourcing, no preservatives. Pick single-ingredient for elimination diets or daily high-volume training; pick WholePrey for micronutrient density and grass-fed sourcing.
