U.S. Air Force military working dog Ddewey, 7th Security Forces K-9, sniffs for hidden contraband in a flower pot June 23, 2015, Abilene, Texas. K-9 handlers from the 7th SFS planted different wires and contraband at the Mall of Abilene during an exercise. This opportunity allowed for the military working dogs to train in a different environment and to work with outside agencies. (U.S. Air Force photo by Senior Airman Shannon Hall/Released)
