Late in the 19th century, European dog breeders became interested in developing dogs from their own countries. In Belgium, it was determined in 1891 that there were four types of herding dogs, each with a different coat but otherwise consistent in appearance. One, with a long, black coat, became officially known as the Groenendael in 1910, borrowing the name from the kennel that had been breeding the black dogs since 1893. The breeder was Nicolas Rose, whose foundation dogs -- Picard d’Uccle and Petite -- produced puppies whose names are still seen in pedigrees of modern-day Belgian Sheepdogs.
By the turn of the 20th century, the versatility and work drive of Belgian Sheepdogs were becoming known beyond the pastures of Belgium. Paris and New York used Belgian Sheepdogs as police dogs in this era. Customs agent employed them on border patrols, rooting out smugglers. During World War I, they distinguished themselves as messengers, ambulance dogs, and freighters of heavy gunnery. Belgian Sheepdogs reprised their role as war dogs during the Second World War.
The Belgian Sheepdog Club of America was formed in 1949, and since then this noble breed has done it all: show dog, athlete, police officer, soldier, service dog, searcher and rescuer, watchdog, and tireless backyard tennis-ball fetcher.
