Head and Skull Head imparts its unique individual stamp and is in proportion to body, appearing neither light nor too heavy. Skull lean without exaggerated cheek muscles. Muzzle broad, deep and powerful, never narrow, pointed, short or shallow. Balance of skull and muzzle essential, with muzzle never appearing small, viewed from any angle. Skull cleanly covered, showing no wrinkle, except when alerted. Creases present from root of nose running down sides of muzzle. Dark mask confined to muzzle, distinctly contrasting with colour of head, even when white is present. Lower jaw undershot, curving slightly upward. Upper jaw broad where attached to skull, tapering very slightly to front. Muzzle shape completed by upper lips, thick and well padded, supported by well separated canine teeth of lower jaw. Lower edge of upper lip rests on edge of lower lip, so that chin is clearly perceptible when viewed from front or side. Lower jaw never to obscure front of upper lip, neither should teeth nor tongue be visible when mouth closed. Top of skull slightly arched, not rounded, nor too flat and broad. Occiput not too pronounced. Distinct stop, bridge of nose never forced back into forehead, nor should it be downfaced. Length of muzzle measured from tip of nose to inside corner of eye is one-third length of head measured from tip of nose to occiput. Nose broad, black, slightly turned up, wide nostrils with well defined line between. Tip of nose set slightly higher than root of muzzle. Cheeks powerfully developed, never bulging.
