Head fairly large, proportionately wider than deep. Skull moderately broad, wide and flat between ears, not domed, wide between eyes. Nose not too short, broad, nostrils large and open. A slight wrinkle, preferably broken, may extend from the cheeks to the bridge of the nose in a wide inverted ‘v’. This must never adversely affect or obscure eyes or nose. Pinched nostrils and heavy over-nose wrinkles are unacceptable and should be heavily penalised. Muzzle must be evident, but may be relatively short and wide. Firm underjaw. Lips not obscuring a well defined chin. Defined stop. Black pigment essential on nose, lips and eye rims.
