AMERICAN BULLDOG BREED STANDARD



The standard describes two types of American Bulldogs and these types are;

1. Johnson, Bully, or "Classic" type

2. Scott, Performance, or "Standard" type

They are named after the breeders who were influential in developing them and they were Mr. John D Johnson (Bully) and Mr. Allan Scott (Standard).


Many of today's American Bulldogs are a combination of the Classic and Standard types. This has resulted in a third type referred to as  "Hybrid" and they will fall under either Classic or Standard American Bulldog Breed Standards.
