Hispano-Breton horses were developed by crossing native Pura Raza Espanola horses with imported Breton draught horses. They are found mainly in two separate areas of northern Spain: Castile and Leon and parts of neighboring Cantabria; and the Pyrenees of Catalonia. They are listed in the Catalogo Oficial de Razas de Ganado de Espana in the group of autochthonous breeds in danger of extinction.
