One of the hardest things for Army Sgt. Jason Bos to do in 2012 when a back injury forced him to retire from the military was say goodbye to his beloved bomb-sniffing dog he had affectionately nicknamed Cici. The two had worked closely together for five years in Iraq sniffing out roadside bombs and searching for hidden weapons, ultimately forming a bond that Jason would not soon forget. The chocolate lab was only 5 when Jason left the military, meaning she still had plenty of good years left to stay and put her doggie-duties to work. About a month ago, however, Jason came across a posting on Facebook explaining that Cici was due to be retired. It wasn’t long before the kennel master at Jason’s former base got in touch with the soldier about formally adopting her. Jason jumped at the chance to be reunited with his four-legged friend, and a truly touching moment happened last at Chicago O’Hare airport. Grab some tissues and watch it here.
