The head, comprising both the skull and muzzle, of the Belgian Sheepdog is one of the chief indicators of breed type and should be unique to the Belgian Sheepdog. Without proper proportions, this uniqueness is not possible, and the head becomes common and untypical. The standard requires that the skull never be wider than its length. The Standard also requires that the muzzle should be as long as the skull. The head should be in proportion to the rest of the body, with clean, well-defined lines and no looseness of skin anywhere on the face or lips. The stop is clearly defined but not deep or abrupt. The plane of the top of the muzzle should run on a line parallel to the plane of the forehead. There should be no cheekiness. Rather, there should be a slight chiseling under the eyes and flatness which permits the eyes to assume their proper placement and their proper part in expression.
