A mismark is a very serious color fault in the Pembroke Welsh Corgi for the show ring.

搭档标志在竞赛是很严错。

Please note that it is perfectly acceptable to have a Pembroke Welsh Corgi that is black and tan with no white, but a Pembroke Welsh Corgi that is black and white with no tan present is a mismark.

请注它是可完美PWC,它有黑色和褐色无白色，但是PWC这又黑色和白色无褐色是错误标记。
