The head of the Manchester Terrier is long, narrow, tight skinned and almost flat with a slight indentation up the forehead. It resembles a blunted wedge in frontal and profile views. There is a visual effect of a slight stop as viewed in profile.
The muzzle and skull are equal in length. The muzzle is well filled under the eyes with no visible cheek muscles. The underjaw is full and well defined and the nose is black.
Tight black lips lie close to the jaw. The jaws should be full and powerfull with full and proper dentition. The teeth are white and strongly developed with a true scissors bite. Level bite is acceptable.
