Jack Russell Terrier Information
History
Jack Russell Terriers are a small but courageous strain of working terrier.
Over the years breeders have focused on working ability versus a specific type. As a result the breed standard is very broad and not pure bred per se, as they have a broad genetic make-up.
Founded in Devonshire, England in the mid-to -late 1800’s by Reverend John Russell who bred terriers for fox hunting. Our modern day Jack Russell has changed very little from this because it has been preserved in England for hundreds of years.
