What Is the History of Jack Russell Terriers?
The Jack Russell terrier originated in the early 1800s when the breed was created by Reverend John “Jack” Russell, who was a hunting enthusiast.

The initial origins of the Jack Russell terrier can be traced to a mix between the fox terrier and the English terrier, which is a now-extinct dog breed.
