American Bulldog

The American Bulldog is a breed of domestic dog (Canis lupus familiaris). Though larger in size, they are the closest surviving relative of the Old English Bulldog, because they were not altered to as great an extent while in America as their European cousins. There are generally considered to be two types of American Bulldog, the Johnson type and the Scott type. These types are named after the breeders who were influential in developing them, John D. Johnson and Allen Scott. These are more commonly known as Classic, or Bully type, and Standard, or Performance type.
