The American Bulldog descends from working bulldogs that settlers brought to the colonies. It became an all-purpose farm dog in the South, catching loose cattle and feral hogs and guarding homesteads. The breed nearly disappeared after World War II until John D. Johnson and Alan Scott revived it, producing a heavier, shorter-muzzled bully type and a leaner, more athletic standard type. Many dogs today are a mix of both.
Adults weigh roughly 60 to 115 pounds and are mostly white, with a short coat that sheds moderately year-round. Many are affectionate and devoted at home, with a confident, protective streak, so early socialization and steady reward-based training matter. In Portland, expect to manage mud and wet paws for much of the year, and read lease terms carefully, since some landlords and insurers restrict bully breeds.
