Broad, almost flat, forehead very bulging. Superciliary arches prominent, separated by a particularly developed furrow between the eyes. The furrow must not extend onto the forehead. Occipital crest is hardly developed. Broad, very short, turned up, nostrils well open and symmetrical, slanting towards the rear.
Lower jaw shows a broad curve, terminating in front of the upper jaw.
This curve is necessary to avoid a too important shifting of the lower jaw. The lower incisors must never be behind the upper incisors in any case. The arch of the lower incisors is rounded. The jaws must not show lateral deviation, nor torsion. The disposition of the incisoral arches should not be strictly delimited, the essential condition being that the upper and the lower lips rejoin to completely cover the teeth.
