Meet Sergeant Stubby: World War I dog veteran, decorated war hero, American icon, and above all, man's best friend. Stubby's story begins in 1917 when America is about to enter the war. A stowaway dog befriends Private James Robert "Bob" Conroy at the Connecticut National Guard camp at Yale University and the two become inseparable. Stubby also wins over the commanding officer and is soon made an official member of the 102nd Infantry of the 26th division. What follows is an epic tale of how man's best friend becomes an invaluable soldier on the front lines and in the trenches, a decorated war hero and an inspiration to a country long after the troops returned home.
