Muscular, athletic, and undeniably powerful, the American Bulldog may be an intimidating looking breed, but they have a heart of gold and a huge penchant for playtime. They come in two types, the Johnson (aka the Bully or Classic type) and the Scott (aka the Standard or Performance type), the prior having a larger, heavier build and a shorter muzzle more similar to the English Bulldog, the latter being more athletic with a longer muzzle and more squarish head, but many are now a combination of the two.

Although confused with the often-vilified American Pit Bull Terrier, the American Bulldog is a different breed entirely. They have a variety of characteristics that make them not only great working dogs but excellent family dogs. Despite their tough-looking exterior, they are actually highly-emotional dogs that are sensitive to their surroundings, which is one reason they make exceptionally good family dogs. They are a gentle, affectionate breed with a high level of overall confidence, a combination that often translates into loyalty, obedience and strong protective nature. Because of these characteristics, they can be shy towards strangers and even other dogs, so training early on will help to ensure they make good company in all social circles. They are also a high energy breed and generally do best with an open yard to run around in, but are able to adapt to apartment living as long as their owners have an active lifestyle they're able to join in on.

Making its way into the United States in the 1800s, immigrants brought their working Bulldogs with them in order to make life in the new country easier. This breed was especially popular in the Southern States, thanks to its ability to bring down and catch feral pigs. As the working dog of farmers and ranchers, the American Bulldog was also used for bull, buffalo and bear-baiting. During WWII, the breed almost died out, but could still be found as cattle and livestock dogs and farm protectors in the south-east. Thanks to a man named John D. Johnson of Summerville, Georgia, he saved the breed from extinction by selecting the best of the breed he could find and started a selection program.
