The German Shepherd Dog (GSD, also known as an Alsatian), (German: Deutscher Schäferhund) is a breed of large-sized dog that originated in Germany. German Shepherds are a relatively new breed of dog, whose origins date to 1899. As part of the Herding group, the German Shepherd is a working dog developed originally for herding sheep. Because of their strength, intelligence and abilities in obedience training they are often employed in police and military roles, in forces around the world. Due to their loyal and protective nature, the German Shepherd is one of the most registered of breeds.
In Europe during the 1800s, attempts were being made to standardize breeds. 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, where shepherds selected and bred dogs that they believed had traits necessary for herding sheep, 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 should be bred also for appearance. While unsuccessful in their goal, the Phylax Society had inspired people to pursue standardising dog breeds independently.
