Senior Airman Brian Claypool, 22nd Security Forces Squadron military working dog handler, encourages his dog, Rakker, with a toy Sept. 10, 2013, at McConnell Air Force Base, Kan. Dogs assigned to the 22nd SFS kennel section receive specialized training once a year at the base pool to familiarize them with bodies of water and encourage them to properly perform working duties in an environment they are not typically exposed to.
