Soldier rescues a puppy and then realizes he can't live without her

The soldier’s job was to disarm homemade bombs and IEDs. While Sean Lilo was working he found a puppy trapped under concrete. It took a while for him to gain her trust, but when he did he fell in love with her. He took her on work trips and she became the morale of the entire camp. At first, they thought she was a boy, so she got the name Barrie, but eventually they realised she was a girl! Sean ended up taking her home from Syria.
