Jack Russell Terrier History & Origin

Developed in England by Reverend John Russell in the early 1800s, the breed was intended to be a courageous fox hunter that could follow quarry into the ground.

Named after Reverend John 'Jack' Russell who developed the breed in Devonshire.

The breed was used primarily for fox hunting and ratting.

The American Kennel Club recognizes a similar breed as the Parson Russell Terrier; however, Jack Russells are often registered with other organizations.

They gained popularity through TV and movies, most notably with 'Eddie' on *Frasier* and 'Wishbone'.
