2) On the sides of the muzzle and on the cheeks;
3) On the underside of the ears;
4) On all feet and/or legs;
5) Under the tail;
6) On the chest, optional; presence or absence shall not be penalized.
Tan markings which are not readily visible or which amount only to traces, shall be penalized. Tan on the muzzle which extends upward, over and joins shall also be penalized. The absence of tan markings in the Black or ASCOB variety in any of the specified locations in any otherwise tan-pointed dog shall disqualify.
