The Giant Schnauzer is a working breed of dog developed in the 17th century in Germany. It is the largest of the three breeds of Schnauzer—the other two breeds being the Standard Schnauzer and the Miniature Schnauzer. The Giant Schnauzer is a working breed of dog developed in the 17th century in Germany. Originally bred to assist on farms by driving livestock to market and guarding the farmer's property, the breed eventually moved into the city, where it worked guarding breweries, butchers' shops, stockyards and factories. It was unknown outside of Bavaria until it became popular as a military dog during World War I and World War II. In modern times, the Giant Schnauzer is used as a police dog; is trained for obedience, dog agility, herding, search and rescue, and schutzhund; and is shown in conformation shows. They are also used for carting. In Europe, the breed is considered to be more of a working dog than a show dog.
