The American Bulldog is a large breed of utility dog descended from the now-extinct Old English Bulldog. As a working breed, they are good on pigs as catch dogs and decent on cattle: they stand their ground when challenged by an angry steer and still retain the herding instinct. Overall, the American Bulldog is a breed that truly falls in love with his family and will do anything to keep it safe if the dog correctly senses danger up to, and including, risking its life to save them.
