Sgt. Stubby: An American Hero (2018)

World War I is not far off. A small dog with a short and stubby tail makes his way into the camp where Robert Conroy, a U.S. Army member, is staying. Conroy befriends the dog, and together they go on a life-changing journey. Lacking any prior training, the friends take to the French trenches, where they meet Gaston Baptiste and engage in acts of courage that will change the world forever.
