The Karst Shepherd is an ancient livestock guardian breed native to the Karst Massif region of Slovenia. It was developed over centuries to guard livestock from predators such as wolves and bears. The breed's history is tied to the rugged Karst Plateau, where its protective and independent nature was shaped by the demands of its working environment. According to one source, the breed was originally recognized by the FCI in 1939 under the name Illyrian Shepherd Dog, and was renamed to Karst Shepherd in 1968. However, recognition status varies by registry, and the exact timeline of its development is not fully documented. The breed's origins are solely in Slovenia, and it has been used for guarding livestock for many generations.
