How many types of Belgian Laekenois are there?

There is only one type of Belgian Laekenois. It is one of the four varieties of the Belgian Shepherd Dog; the other three are the Belgian Malinois, the Belgian Tervuren, and the Belgian Groenendael (which is called the Belgian Sheepdog in the United States). Each is named after a different region or town in Belgium. These four varieties share a common origin and physical characteristics but differ primarily in coat type and color.
