A disproportionately narrow skull is to be penalized. Viewed from the side, the topline of the skull is slightly flattened. The length of the muzzle, measured from stop to the end of the nose, is equal to the length of the skull, measured from occiput to stop. The jaw is strong and the muzzle is full and well-filled in under the eyes. When viewed from the side, the line of the underjaw is almost parallel to the top line of the muzzle.
Lips are black and tightly closed.
The Canaan Dog has a complete set of good-size, evenly spaced, white teeth meeting in a scissors or level bite. The nose is solid black. In some light-colored dogs, the pigment of the nose may fade somewhat during the winter months. This is not desirable but should not be severely penalized. In profile, the nose is on the same line as the top of the muzzle and extends somewhat beyond the lower jaw .
