German Shepherd

The German Shepherd (German: Deutscher Schäferhund, German pronunciation: [ˈʃɛːfɐˌhʊnt]) is a breed of large-sized working dog that originated in Germany. The breed's officially recognized name is German Shepherd Dog in the English language, sometimes abbreviated as "GSD", and was also formerly known as the Alsatian and Alsatian Wolf Dog in Britain. The German Shepherd is a relatively new breed of dog, with their origin dating to 1899. As part of the Herding Group, German Shepherds are working dogs developed originally for herding sheep. Since that time, however, because of their strength, intelligence, trainability and obedience, German Shepherds around the world are often the preferred breed for many types of work, including assistance, search-and-rescue, police and military roles, and even acting. The German Shepherd is the second-most popular breed of dog in the United States and fourth-most popular in the United Kingdom.
