Ears-Erect, firm, and of medium size, tapering slightly to a rounded point. Ears are mobile, and react sensitively to sounds. A line drawn from the nose tip through the eyes to the ear tips, and across, should form an approximate equilateral triangle. Bat ears, small catlike ears, overly large weak ears, hooded ears, ears carried too high or too low, are undesirable. Button, rose or drop ears are very serious faults.
