The 7th Security Forces Squadron bid farewell to one of their own as they honored military working dog Sam during a fallen solider memorial March 8, 2012, at Dyess Air Force Base, Texas. After completing more than 100 days of Military Working Dog Training at Lackland AFB, Texas, Sam arrived at Dyess Air Force Base in August 2003. Like most military working dogs, he was dual-certified in explosive detection and patrols.(U.S. Air Force photo by Airman 1st Class Jonathan Stefanko/Released)
