Like their human counterparts dogs serve valiantly in the United States armed forces in war zones around the world. These military dogs are used to find explosives, insurgents and drugs, and to help search for missing people. When their careers end after serving overseas canine veterans retire, usually at the age of 8 or 9. They can be adopted through the non-profit Military Working Dog Adoptions. Although there is no fee charged for adopting a war dog, prospective owners are expected to pay the cost of shipping the four-legged retirees home (about$2000.00). Some 300 of these dogs are available each year but demand for them has increased dramatically since the story of Cairo, the Navy SEALs dog who worked on the Bin Laden mission, hit the news.
