Dax, 18th Security Forces Squadron military working dog, and Staff Sgt. Ralph Rodriguez, 18th SFS MWD handler, walk beside Civilian Guard Shitetsu Hirata, 18th SFS kennel assistant, during control aggression training on Kadena Air Base, Japan, March 28, 2014. Dax had been put on medical hold after injuring his tail, which resulted in a procedure to remove it, as well as getting sick after the procedure. Once he was removed from medical hold, he had passed the time allotted for him to be trained, and was unable to be certified by Joint Base San Antonio-Lackland, Texas. Dax was then brought to Kadena under the condition Kadena trained and certified him. (U.S. Air Force photo by Airman 1st Class Hailey R. Staker)
