PRODUCT LAUNCH – Realistic Bite Sleeve (RBS)

Developed through military working dog and law enforcement K-9 subject matter expert collaboration comes the second installment from the K2 Solutions, Inc.

(K2) – FirstSpear (FS) Joint Tactical Canine Line. The Realistic Bite Sleeve “RBS” was developed to provide a truly realistic finishing touch on aggression training for canines. “We sought to create a two-part finishing sleeve with an outer layer that mimics human flesh texture during a canine bite. The system is ergonomic and low-profile to accommodate a range of training circumstances, including concealed sleeve training.” – Dr. Heidi Alvey, K2 Solutions

The RBS seeks to bridge capability gaps that currently exist in status quo bite training. Most bite sleeves are too bulky for concealment. Others are made of material such as jute that does not provide a truly realistic training scenario, which can reduce canine effectiveness on target due to hesitation. Other silicone products require the trainer to attach additional appendages to a sleeve, which limits training scenarios, eliminating realistic concealment, and may confuse a canine. The RBS provides the canine an authentic human skin texture when biting the actual forearm region, while reducing the circumference of the target. This allows for a full-mouth bite – the bite that a trainer expects from their canine.

“We are excited to work with K2 Solutions on this all new bite sleeve and look forward to seeing how this type of training application will evolve between K2 and FS in the future.” – Ronnie Fowlkes, VP Business Development, FirstSpear.

The K2-FirstSpear Realistic Bite Sleeve System is comprised of an outer silicone “skin” paired with an inner hidden sleeve. The skin is a proprietary prosthetic-grade silicone product that looks and feels like human flesh. It has an internal mesh support system for resilience.


The inner sleeve is a low-profile bite platform constructed from two layers of 4 oz split cowhide to allow for a full mouth bite. Two adjustable straps allow a custom fit for any trainer. The RBS is the ultimate finishing product for canine aggression training designed to ensure your canine is conditioned for real bites in the field. Kevlar inner sleeve available based on training requirements, call for pricing. Patent Pending.
