Cumberland Sheepdog 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.
Illyrian Shepherd The Illyrian Shepherd was a dog breed registered with the Fédération Cynologique Internationale FCI since 1939 under Standard number 41 "Illirski Ovcar". In 1957 the FCI changed the name of the breed to "Yugoslavian Shepherd Dog Sharplanina" (Šarplaninac). Up to 16 March 1968 the Karst Shepherd (kraški ovčar) carried the same name. Since then the two breeds are independent.
