Acceptable colours are blue merle, brindle, red, sable, tri colour with brindle points and tri colour with red points.
All of the above with or without the typical white markings on head, neck, chest, underparts, legs and feet, white tail tip. White should not predominate on body or head where it should never surround the eyes. Nose and eye rims must be black. Liver and dilute colours highly undesirable.
