Sergeant Stubby

In 1917, a small stray mongrel puppy appeared in the training area of the 102nd infantry, near Yale, USA, where the Yankee Division was preparing for action in World War I. Christened Stubby by the soldiers because of his short tail, the puppy soon integrated himself into the ranks. His comrades taught him to "salute", he learned bugle calls, and was allowed to join the soldiers on the front line.

After being caught in a gas attack, he recognized the smell the next time it happened and was able to wake and warn the sleeping soldiers. He also caught a German soldier in the trenches by biting and holding him until relief arrived, and was adept at finding wounded soldiers, too. By the end of the war, Stubby had served in 17 battles, and was awarded lifetime membership of the American legion, as well as a gold medal for heroism commissioned by the Humane Education Society.

Dolphin danger

The playful nature of dolphins is well documented. But what about their protective instincts? In 2004, Rob Howes went swimming with his daughter and two of her friends, off the coast of North Island, New Zealand. There, they found themselves encircled by four bottle nose dolphins who repeatedly slapped their tails on the surface to prevent any of the group swimming away.
