The ears are small . The cheek muscles are very pronounced . The lips show no looseness . The teeth form a scissor bite . The head tapers down to a strong well - muscled neck and shoulders placed on squarely spaced forelimbs . They are tucked up into their loins and the last 1--2 ribs of the rib - cage are usually visible . The tail resembles an old fashioned pump handle . The hind quarters are well - muscled . </P> <P> They are coloured brindle, black, red, fawn, blue, white, or any blending of these colours with white . White with any other colour broken up over the body is known as pied .
