Bully Jack Terrier Breed History

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.

Bully Jack Terrier Breed Maintenance

The Bully Jack Terrier requires little to no maintenance, so he is a perfect dog for those who do not wish to or are unable to spend much time grooming a dog. He does shed a good bit, so brush him two or three times a week during shedding season. Because he has a tendency to shed, he can not be considered hypoallergenic. You should brush your Bully Jack Terrier’s teeth at least three times a week; however, if you want to prevent gum disease, brush the dog’s teeth daily. Trim your dog’s nails every other week; make the grooming regimen a bonding time for you and your Bully Jack Terrier - he'll learn to look forward to it.

He has bull terrier ears that are black and a round big black mark aourd his left eye. His hairhair is all white but he does have little black freckles. He has the allergies that most bull terriers have. He gets all red and stuff. He is fast even tho he has short legs and shorter hands. He is strong and smart. He has a really strong jaw. He is also trained to run on trees. He is also very brave and has a deep bark and growl. But when be is away with a stranger he is just like a puppy. He is so energic and always wants to run and play. He has the shape of bull terrier eyes but with medium size. Not big like Jack Russell and not small like bull terrier. Some kind of a wolf style eyes.
