The coat is short, close, and stiff to the touch. The essential characteristics of the American Bulldog are those which enable it to work as a hog and cattle catching dog, and a protector of personal property. These tasks require a powerful, agile, confident dog with a large head and powerful jaws. The American Bulldog is a gentle, loving family companion who is fearless enough to face an angry bull or a human intruder. Puppies should have early socialization.
Some strains have hip dysplasia.
The breed's strength, courage, and familiarity with livestock led to its popularity in the brutal sport of bull baiting. When this sport was outlawed in England, the original type of Bulldog disappeared from Britain and was replaced with the shorter, stockier, less athletic dog we now know as the English Bulldog. The original Bulldog, however, was preserved by working class immigrants who brought their working dogs with them to the American South. Small farmers and ranchers used this all-around working dog for many tasks. By the end of World War II, however, the breed was almost extinct.
