The Norfolk Terrier originated in East Anglia in England. In the late nineteenth century, English sportsmen developed this dog by crossing local breeds. These included short-legged Irish Terrier breeds and small red terriers used by gypsies in Norfolk.
These dogs became fashionable to keep for students in their dorm rooms at Cambridge University, where they were first called Cantab Terriers. They were later referred to as Trumpington Terriers, after a street in the area they were developed. In the early part of the twentieth century, an Irishman named Frank Jones sold a large quantity of the this breed in the United States, so they were then referred to as Jones Terriers.
This breed was originally designated as a drop-eared version of the Norwich Terrier, but was eventually recognized as its own breed. Part of the reason these two dogs were designated as separate is it was found that mixing the two types of ear carriage resulted in unpredictable ear carriage in the offspring. After many generations of development, these two breeds have gained distinct characteristics of appearance and temperament.
