Preferred colors in competition are dark deer red with or without black hairs lightly interspersed. Black with red-brown markings on the head, chest, legs, feet, and tail are also permitted, as well as a white star on the chest (according to the American Rare Breed Association). The ideal height for dogs is 37–38 cm, and the ideal height for bitches is 36–37 cm. Strong limbs and feet, with black toenails and tight toes as well as strong elastic skin are features that judges look for in competition. They also look for a trotting gait. The top coat should be very thick, the undercoat dense and both closefitting to the body.
