10 Incredible Animal War Heroes

10. Sergeant Stubby

In 1917, a soldier came across a stray dog of indeterminate breed while training on the grounds of Yale University. The US Army didn't have any working dogs at the time, so when his unit deployed, Corporal Robert Conroy smuggled the dog to France with him.

The unit named the dog Stubby due its small stature. This canine warrior went on to become a veteran of 17 battles and the most decorated dog of World War I. Stubby could hear the whine of artillery shells before they hit the ground, warned the unit of multiple gas attacks, and single-handedly (or mouthedly) captured a German spy.

He was injured several times but like all action heroes, he always prevailed. After the war Stubby was made an honourable Sergeant, met three presidents, became a sports team mascot, and got an obituary in the New York Times when he died in 1926. His remains are preserved in the Smithsonian.
