Sgt. Jason Bos worked with a bomb-sniffing dog named Cila when he was deployed in Iraq. On discovering that the dog was to be retired, he was able to convince the kennel master at his former base to let him adopt her.
Here is a video of their tearful (ok, the tears are mine) reunion after Cila’s flight from Frankfurt. My favorite part is when he says he’s going to take her home and let her sleep on the couch.
