Sergeant Stubby was a war dog who warned soldiers of mustard gas and approaching artillery!

Sergeant Stubby was the first war dog for the United States. He had an awesome name, and who could look at that precious face and not fall in love. That’s not even to mention that he was extremely useful on the front line of World War I. The brilliant dog was a Staffordshire Bull Terrier. 

No one really knows where he came from, but he showed up at Yale Field in Connecticut. Corporal Robert Conroy snuck Stubby along to France in the ship with the rest of the troops. In France, Stubby was injured by a German hand grenade. 

He was sent to the back of the lines where he was able to recover and improve morale at the same time. Stubby was a highly decorated dog, and was the only dog to “be promoted to sergeant through combat.” He learned to warn the troops around him of mustard gas and oncoming artillery. 

He also single-handedly took down a German spy. He also found injured, but alive soldiers in no man’s land, and comforted and helped rescue them. After the war, Stubby went home with Conroy. He was instantly a celebrity and received many medals for his 18 month service in the war.
