The American Bulldog descended from bulldogs originally bought over by English and Welsh migrants into the US territory in the 18th century. The dog became a popular breed in the American south as a farmworker and was employed to hunt wild hogs that were seen in that region. Near World War II, the breed lost its popularity and was on the verge of extinction. Until a renewed interest brought about a revival of the species. Today we see the American Bulldog has an uncanny resemblance to his English cousin. The dog's legs are much longer, and his jaws protrude less. He usually has white and brown fur. This dog breed is used as a working dog.
