　　The German Shepherd Dog (GSD), (German: Deutscher Schäferhund) is a breed of large-sized dog that originates from Germany. German Shepherds are a fairly new breed of dog, with their origins only dating back to 1899. Part of the herding group, shepherds are working dogs developed originally for herding sheep. Their strength, intelligence and obedience often sees them employed in police and military roles in forces around the world. Due to their loyal and protective nature the breed is among the most registered.
　　Origins
　　In Europe, during the 1800s, dog breeds were beginning to be standardized. The dogs were bred to preserve traits that assisted in their job of herding sheep and protecting flocks from predators. In Germany this was practiced within local communities, with the shepherds selecting and breeding dogs together that they believed had good traits, such as intelligence, strength, and keen senses of smell. The results were dogs that were able to perform admirably in their task, but that differed significantly, both in appearance and ability, from one locality to another.
　　To combat these differences, the Phylax Society was formed in 1891 with the intention of creating standardised dog breeds in Germany. The society disbanded after only three years due to an ongoing, internal conflict regarding the traits that the society should promote; some members believed dogs should be bred solely for working purposes, while others believed dogs also should be bred for appearance. While unsuccessful in their goal, the Phylax Society had inspired people to pursue standardising dog breeds independently.
　　Max von Stephanitz, an ex-cavalry captain and former student of the Berlin Veterinary College, was one such ex-member. He believed strongly that dogs should be bred for working.
　　In 1899, Von Stephanitz was attending a show when he was shown a dog named Hektor Linksrhein. Hektor was the product of many generations of selective breeding and completely fulfilled what Von Stephanitz believed a working dog should be. He was pleased with the strength of the dog and was so taken by the animal's intelligence and loyalty, that he purchased it immediately.After purchasing the dog he changed its name to Horand von Grafrath and Von Stephanitz founded the Verein für Deutsche Schäferhunde (Society for the German Shepherd Dog). Horand was declared to be the first German Shepherd Dog and was the first dog added to the society's breed register.
　　Horand became the centre-point of the society's breeding programs and was bred with dogs belonging to other society members that displayed desirable traits. Although fathering many pups, Horand's most successful was Hektor von Schwaben. Hektor was inbred with another of Horand's offspring and produced Beowulf, who later fathered a total of eighty-four pups, mostly through being inbred with Hektor's other offspring. Beowulf's progeny also were inbred and it is from these pups that all German Shepherds draw a genetic link. It is believed the society accomplished its goal mostly due to Von Stephanitz's strong, uncompromising leadership and he is therefore, credited with being the creator of the German Shepherd Dog.
　　German Shepherds are a large-breed dog which generally are between 55 and 65 centimetres (22 and 26 in) at the withers and weigh between 22 and 40 kilograms (49 and 88 lb). The ideal height is 63 centimetres (25 in), according to Kennel Club standards.They have a domed forehead, a long square-cut muzzle and a black nose. The jaws are strong, with a scissor-like bite. The eyes are medium-sized and brown with a lively, intelligent, and self-assured look. The ears are large and stand erect, open at the front and parallel, but they often are pulled back during movement. They have a long neck, which is raised when excited and lowered when moving at a fast pace. The tail is bushy and reaches to the hock.
