The Cumberland sheepdog is an extinct dog breed related to the border collie and other old working collie types. It is claimed to be one of the ancestors of the Australian shepherd and in the early part of the 20th century some Cumberland sheepdogs were being referred to as border collies and may have been absorbed into the latter breed.
