Expression - Soft, dark-eyed, inquisitive, alert. Eyes are round, black or dark brown and are set in the skull to look directly forward. An overly large or bulging eye is a fault as is an almond shaped, obliquely set eye. Halos, the black or very dark brown skin surrounding the eyes, are necessary as they accentuate the eye and enhance expression. The eye rims themselves must be black. Broken pigment, or total absence of pigment on the eye rims produce a blank and staring expression, which is a definite fault. Eyes of any color other than black or dark brown are a very serious fault and must be severely penalized. Ears are drop and are covered with long flowing hair. When extended toward the nose, the leathers reach approximately halfway the length of the muzzle. They are set on slightly higher than eye level and rather forward on the skull, so that when the dog is alert they serve to frame the face. The skull is slightly rounded, allowing for a round and forward looking eye. The stop is slightly accentuated. Muzzle - A properly balanced head is three parts muzzle to five parts skull, measured from the nose to the stop and from the stop to the occiput. A line drawn between the outside corners of the eyes and to the nose will create a near equilateral triangle. There is a slight degree of chiseling under theeyes, but not so much as to result in a weak or snipey foreface. The lower jaw is strong. The nose is prominent and always black. Lips are black, fine, never drooping. Bite is scissors. A bite which is undershot or overshot should be severely penalized. A crooked or out of line tooth is permissible, however, missing teeth are to be severely faulted.
