The Belgian Shepherd Groenendael is one of four varieties of the shepherd dogs that were developed in Belgium in the late 1800s. The four varieties are the Malinois (fawn-mahogany, short coat with black mask), Tervuren (Fawn-mahogany, long coat with black mask), the Laekenois (Fawn, rough coat), and the Belgian Sheepdog, or Groenendael (black, long coat).
The black-coated Belgian Sheepdog was developed by breeder Nicolas Rose in the 1890s with the features of square, medium size dog with well-set triangular ears and dark brown eyes. This dog was popularized due to its versatility in work as it can be used as a police dogs in Paris and New York in the 1900s. In Belgium, customs officers patrolled the border with them too.
