Groenendael

The Belgian Shepherd (Dutch: Belgische Herder), also known as the Belgian Sheepdog (Dutch: Belgische Herdershond) or the Chien de Berger Belge, is a Belgian breed of herding dog of medium size. It is bred in four distinct varieties based on coat type and colour: the long-haired black Groenendael; the rough-haired fawn Laekenois; the short-haired fawn Malinois, and the long-haired fawn Tervueren. The American Kennel Club considers the four varieties to be separate breeds.
The breed descends from a common type of shepherd dog found throughout Western Europe that includes such modern breeds as the Bouvier des Ardennes, Dutch Shepherd and German Shepherd, and was a common sight in the service of Belgian shepherds for centuries. At the end of the nineteenth century a breed club was formed and attempts were made to standardise the breed.
Its historical role was as a herding dog. It is also commonly kept as a companion dog, or used as an assistance dog, detection dog, guard dog, guide dog, police dog or search and rescue dog. It has a long history of being used by Belgian police as well as military forces, serving for Belgian armed forces in both World Wars. In the twenty-first century it is in use by a number of armed forces worldwide in a variety of roles.
