The Pembroke Welsh Corgi originated in Pembrokeshire, Wales as a livestock herding dog. According to Welsh legend, they sprang from the lairs of fairies and elves. Historians say they descended from Vallhunds brought to Wales by Vikings in the 9th and 10th centuries. Others say they were descended from dogs brought by Flemish weavers during 12th century. They are the younger of the two Corgi breeds. You can tell them apart from the Cardigan Welsh Corgi because Cardigans have a long tail and Pembrokes have a stubby tail.
