Elegant and proud, the Belgian Sheepdog is strong, but not bulky. During WWI, Belgian Sheepdogs distinguished themselves on the battlefields, serving as message carriers, ambulance dogs, and even pulling machine guns. It is no wonder that today this breed performs well in sports like obedience, herding, and tracking. They are also excellent workers, and work as search and rescue dogs, guide dogs, and therapy dogs. This breed is completely black, or may be black with white, although there are limitations to their white markings.
