Military Working Dogs (MWDs) provide critical capabilities in operations, which include assisting with patrols, combat tracking, and detection of mines, explosives, and narcotics. Like all canines, MWDs can be susceptible to heat injuries. The Canine Thermal Model and Monitor (CTMM) effort seeks to reduce heat injuries in MWDs through near real-time monitoring of MWD core body temperature. CTMM will leverage data collected from this canine thermal monitor along with environmental conditions (e.g., humidity, temperature), measured activity level, and geolocation data to optimize tactical deployment, mitigate environmental casualties, and preserve these high value combat assets. Through this RFI, WRPBH is seeking information on canine thermal and environmental monitors and enhanced engineering solutions to inform and guide CTMM development and fielding.
