Sgt. Stubby: An American Hero (2018)

With the world I looming, a young army Robert Conroy is adopted by a stray, stump-tailed terrier and has his life forever changed when a little dog with a stubby tail wanders into camp as the men of the 102nd Infantry Regiment train on the grounds of Yale University. Conroy names his new friend Stubby and gives him a home, a family, and a chance to embark on the adventure that would define a century.
