Sergeant Stubby – War Dog. Called the most decorated war dog of WWI, Stubby was an American dog, named “Stubby” due to his short tail, he was described as of “uncertain breed,” but probably came from the family of Boston Terriers. He was snuck into a troop ship from Connecticut to France, being allowed to stay on board as he boosted morale for the soldiers. Being injured by mustard gas in his first year of battle, Stubby developed a sense for the smell of gas and learnt to warn his unit of poison gas attacks, whilst also being able to locate wounded soldiers and give warning of attack, hearing the enemy coming long before human ears. On one occasion he grabbed a German spy who had snuck into their camp, biting his leg until someone came to help.
