Sgt. Stubby, the Heroic War Dog

From an email. Links about the story follow.

In honor of all our Veterans I thought this little bit of history was interesting to share.

Meet America’s first war dog, a stray Pit Bull/Terrier mix, named Stubby. He became Sgt. Stubby, was the most decorated war dog of World War I and the only dog to be promoted to sergeant through combat.
One day he appeared at Yale Field in New Haven, Connecticut; while a group of soldiers were training, stopping to make friends with soldiers as they drilled. One soldier, Corporal Robert Conroy, developed a fondness for the dog. He named him Stubby because of his short legs. When it became time for the outfit to ship out, Conroy hid Stubby on board the troop ship. In order to keep the dog, the private taught him to salute his commanding officers warming their hearts to him.
