Bulldogs were brought to South America by farmers and ranchers who used them for guarding stock, hunting and just as general working farm dogs. During World War II this breed was near extinction. John D. Johnson and his father played an important role in reviving the Bulldog breed. They sought out the best specimens for breeding and made a big difference in rebuilding the population of Bulldogs. Another man named Alan Scott also became involved in their breeding process. The two men eventually started doing some cross breeding of their own which resulted in Alan Scott’s dogs becoming the American Bulldog while John Johnson began crossing his line with English Bulldogs. The American Bulldog is taller, faster and more agile than the English Bulldog.


American Bulldogs have very stocky, muscular bodies for their medium sized frame. They have large heads in proportion to their body, but they are taller and more agile than the English Bulldog. They are found in many colors including every shade of brindle.  Typically American Bulldogs are at least 50 percent white with patches of color or they are solid white. Their coats are smooth and short and shed an average amount. American Bulldogs have a variety of acceptable ear types including cropped, half-pricked, rose or folding forward. These dogs have a large variation in their size and weight, so its common for some to be outside the typical range of 60-120lbs (27kg-54kg). American Bulldogs are known to drool and slobber a lot.


American Bulldogs are loyal, courageous and protective making them lovely family companions. They can be competitive against another dogs, but should not be hostile. They were originally bred to fight and be heroic, so with these genetic traits they need to be trained and socialized so they aren’t aggressive towards other dogs or wary towards strangers. They are good with children and form strong bonds with their family. They can demand a lot of attention with their emotional personalities.


Early socialization is important with American Bulldogs, if they are well socialized from puppyhood then they shouldn’t have any problems living with other animals or being overly protective with strangers. They need an owner who is firm and consistent, otherwise American Bulldogs can take on the role as pack leader without proper obedience training.


American Bulldogs need an average amount of exercise and should have a decent sized yard to run around in. Although they are not demanding with physical activity it is good that they get regular walks to help keep them stimulated both physically and mentally as they tend to be quite inactive when indoors.


American Bulldogs are average shedders and are low maintenance with grooming. A brush now and then with a firm bristle brush will help with the shedding. They only need to be bathed as necessary.
