The Villano de Las Encartaciones is a Spanish breed of large working dog from the region of Las Encartaciones in the province of Biscay, in the Basque country; it is found also in Álava, in eastern Cantabria and in northern Burgos. The traditional use of the dogs is in management of the Monchina breed of cattle of Cantabria and the Paìs Vasco, and particularly to assist with bringing the cattle down from the mountain pastures between October and December. In 2009 there were fewer than 200 dogs registered in the studbook.
