2017 film Rex, starring Kate Mara, tells the story of US marine corps German Shepard, Rex, and his handler, Megan Leavey. This autobiographical drama depicts the true story of the young soldier and her work alongside her life-saving dog during tour in Iraq. An incredible bond forms between the two, and Rex becomes known as one of the best US sniffer dogs. When both are injured in an explosion, Megan must return home, and struggles to cope with the symptoms of PTSD without her canine friend.

This is the heartwarming true story of a US soldier and her partner, and the relationship between Rex and Megan will make you smile. This movie really shows the work of these animals in wartorn countries, and the effects of working on the front line. I recommend this movie to animal lovers, as the story is told with a brilliant cast and a wonderful dog.
