American Bulldogs descend from working bulldogs brought to the colonial South, where they caught loose cattle and feral hogs and guarded farms. The breed nearly vanished after World War II until John D. Johnson and Alan Scott revived it, leaving two broad types: the heavier, shorter-muzzled Johnson or bully type and the leaner, more athletic Scott or standard type. Most are mostly white and weigh 60 to 115 pounds.
In Grand Prairie, that history shows up as a dog that wants both a job and a family. Many are affectionate, confident and protective, with the stamina for long walks on the EpicCentral loop. Their strength makes early socialization, reward-based training and secure leashing important. Many shelter dogs labeled American Bulldog are mixes, so size and energy vary from dog to dog.
