This dog was originally used for fights against bulls, hence its name. Since fighting was banned, farmers 'modified' this breed and this dog is absolutely not aggressive! Stocky with short legs, it has droopy lips and his head is crushed. His hair is short and smooth, white, fawn or red. This is a very loving dog and protective with his family: in time, it can show great courage! But it is also a lazy and stubborn companion: you must educate him firmly!
