Named for the town of one of its biggest supporters, this was the least popular of the Belgian herders. The breed was so unpopular that it died out altogether by the Great Depression and had to be recreated. It is better at herding than guarding, an unusual trait for the Belgians.
If you can give this dog the proper amount of exercise and mental work, it can be a grand companion. Without those tasks and play, it can be mischievous. It is not interested in meeting strangers but needs sufficient interactions with humans. This is not a dog for homes with children as it may nip at heels to herd them.
