It usually gets along well with other animals, is particularly fond of children, and does best indoors. The Bulldog was bred in the early 13th Century. The short muzzle and wide lower jaw were needed for the dog to clamp itself to the bull’s nose like a vise. The last of the working Bulldogs in England were crossed with Pug Dogs to create a stocky, docile, family pet-known today as the English Bulldog.
