📖 Breed History

Thought to be a cross of the Mastiff and the Pug, the English Bulldog breed was developed in England during the 19th century. The first English Bulldogs were larger than they are today, weighing about 80 pounds. They were bred to be aggressive, courageous, and determined, originally used for bull-baiting. However, bull-baiting was outlawed in England in 1835, leading to the rise of dog fighting, which was easier to conceal from authorities. Over time, the breed was bred to be a gentler companion, leading to a happier life. The English Bulldog was officially recognized by the American Kennel Club in 1886 and has since become the official mascot for many schools, universities, sports teams, and the United States Marines. It is also a popular choice among celebrities such as Pink, Adam Sandler, and Reese Witherspoon.

The Jack Russell Terrier originated in England in the 1800s. A student named John Russell purchased a small white and tan Terrier from a local milkman in 1819, naming him Trump. Trump resembled a Wire Fox Terrier but had shorter legs. Russell, an avid hunter, began breeding Trump with the goal of developing a Terrier with high stamina and courage to chase foxes out of their dens. By the 1850s, Trump’s offspring were recognized as a distinct breed. The Fox Terrier Club was formed in 1875, with Russell being one of the founding members. In 1982, a Jack Russell named Bothy made history by becoming the first dog to travel to both the North and South poles as part of the Transglobe Expedition with his owner Ranulph Fiennes and Charles Burton. The Fox Terrier and the Jack Russell of today are descendants of Trump, and the breed continues to be highly regarded for its energy and bravery.
