The 'ideal' head is of medium length, deep through broad skull (rounding of muscle on each side of median line) very pronounced cheek muscles, distinct stop; and ears are set high. Ears are cropped or uncropped, the latter preferred. Uncropped ears should be short and held half-rose or prick (not many prick ears seen today). Full drop to be penalized. Eyes dark and round, low down in skull and set far apart. No pink eyelids. Muzzle is medium length, rounded on upper side to fall away abruptly below the eyes. Jaws well defined. Underjaw to be strong and have biting power. Lips close and even, no looseness. Upper teeth to meet tightly outside lower teeth in front. Nose definitely black.
