May be cropped or uncropped, but are usually cropped to an equilateral triangle for health reasons. If uncropped, they are medium sized, triangular in shape, held tight to the cheeks, and not extending beyond the lower margin of the throat. Skull - Wide, flat between the ears, slightly arched at the frontal part, and covered with wrinkled skin. The width of the cranium between the cheekbones is approximately equal to its length from occiput to stop. The brow is very developed.
Frontal furrow is marked.
Occiput is barely apparent. Stop - Very defined, forming a right angle at the junction of muzzle and frontal bones, and then sloping back at a greater angle where the frontal bones meet the frontal furrow of the forehead. Nose - Large with well opened nostrils, and of the same color as the coat. The nose is an extension of the top line of the muzzle, and should not protrude beyond nor recede behind the front plane of the muzzle. Severe fault - Depigmentation of the nose.
