Breed History

Since the Jack Highland Terrier is a fairly new hybrid, not much is known about its history. Understanding the lineage and history of the parent breeds can give an insight into the Jack Highland Terrier, its characteristics, temperament, etc.

The origin of the Jack Russell Terrier can be traced back to the 1800s to the United Kingdom, where they were bred to track and hunt foxes along with foxhounds. Because of their smaller size, Jack Russell Terriers could get into tight spaces more efficiently.

The West Highland White Terrier, popularly known as Westie was developed in Scotland. In 1906, the breed was recognized by the England Kennel Club and came to the US in 1908, when it was known as the Roseneath Terrier.

In 1909 the breed was recognized by the AKC and the name was changed to West Highland White Terrier. Westies were also bred as hunting dogs to hunt small game such as rabbits, rats, badgers and foxes.
