In 2008 Navy SEAL Will Chesney became a dog handler and was eventually matched up with Cairo, a standoffish dog who was all work and no play. When they deployed to Afghanistan in 2009, Cairo proved his abilities by distinguishing between the enemy and civilians. He was later shot in the chest and leg but recovered. In 2011, Chesney, Cairo, and the SEAL team were sent after Osama bin Laden in what was known as Operation Neptune Spear. In 2013 Cairo retired, and Chesney was able to adopt him a year later after jumping through numerous hoops. However, only a few months later his body began to deteriorate at a much faster rate due to the stress and work he had been through. In 2015, Cairo was put down, and Chesney has since announced that a book is being written on the dog.
