The Villano de las Encartaciones (Basque: Enkarterriko billano, Cantabrian: Villanu, English: Villein of las Encartaciones) is a Spanish working dog originated in Las Encartaciones, a comarca of the province of Biscay, in the Basque country, eastern Cantabria and northern Burgos. The Villano derived from the Spanish Bulldog, of which it represents a lighter, faster and more agile version. The dog is used to catch Monchina cattle, which are raised in a feral state in northern Spain. The Villano is also used for boar hunting given its qualities as a catch dog. Males stand 60 to 65 cm at the shoulder and weigh up to 35 kg.
