Head

The head properties are of great importance. When considered in proportion to the size of the dog the head is inclined to lightness and never appears massive. A heavy-headed dog lacks the necessary bright, alert, full-of-sense look that contributes so greatly to expression. Both in front and profile view the head bears a general resemblance to a well-blunted lean wedge, being smooth and clean in outline and nicely balanced in proportion. On the sides it tapers gradually and smoothly from the ears to the end of the black nose, without being flared out in backskull (cheeky) or pinched in muzzle (snipy). In profile view the top of the backskull and the top of the muzzle lie in two approximately parallel, straight planes of equal length, divided by a very slight but perceptible stop or break. A mid-point between the inside corners of the eyes (which is the center of a correctly placed stop) is the center of balance in length of head.

The end of the smooth, well-rounded muzzle is blunt but not square. The underjaw is strong, clean-cut and the depth of skull from the brow to the under part of the jaw is not excessive. The teeth are of good size, meeting in a scissors bite. Overshot or undershot jaws are undesirable, the latter being more severely penalized. There is a very slight prominence of the eyebrows. The backskull is flat, without receding either laterally or backward and the occipital bone is not highly peaked. The proper width of backskull necessarily depends upon the combined length of skull and muzzle and the width of the backskull is less than its length. Thus the correct width varies with the individual and is dependent upon the extent to which it is supported by length of muzzle. Because of the importance of the head characteristics, prominent head faults are very severely penalized.
