The Bully Jack Terrier is a fairly rare hybrid breed. To further understand the hybrid, we must look at its parent breeds. The Bull Terrier was originally bred as a fighting dog in the 19th century. Most experts believe that the Bull Terrier was a cross between a bulldog and the now-extinct white English Terrier. The Bull Terrier was known as a “gladiator” for his skill in the fighting ring. Although the Bull Terrier was a renowned fighting dog, when in the company of humans, he was nothing but courteous to humans. This characteristic prompted the nickname “White Cavalier.” General George S. Patton was quite a fan of the Bull Terrier; his dog Willie followed him everywhere. Author John Steinbeck and President Woodrow Wilson were also fans of the breed. A Bull Terrier named Patsy Ann greeted each ship that docked in Juneau, Alaska, and was eventually named the official greeter of Juneau. Of course, the most popular Bull Terrier is the infamous Budweiser mascot, Spuds Mackenzie. The Jack Russell Terrier is not without Hollywood recognition. Willie Morris’ book and later movie adaptation My Dog Skip featured a Jack Russell Terrier as young Willie’s best friend. The Jack Russell originates in southern England in approximately the mid to late 1800s. He was a favorite of hunters who preferred to be on horseback during the hunt. He was brought to the United States in the 1930s. His main purpose was hunting with other hounds; his job was to flush foxes out of their dens so that larger hounds could chase them. The Bully Jack Terrier is recognized by the following organizations: Designer Breed Registry and International Designer Canine Registry.
