American Bulldog

The American Bulldog is a breed of working dog that was developed in the United States. There are generally considered to be three types of American bulldog: the Bully or Classic type (sometimes called the Johnson type ), the Standard or Performance type (also called the Scott type), and the Hybrid type. The names associated with the Bully and Standard types are those of the breeders who were influential in developing them, John D. Johnson (Bully) and Alan Scott (Standard). American Bulldogs are thought to be descended from working type bulldogs found commonly on ranches and farms in the Southern and Midwestern parts of the United States.
