The Rocky Mountain Jack Russell Terrier Network (RMJRTN) is the Colorado affiliate of the Jack Russell Terrier Club of America (JRTCA). The JRTCA is committed to the preservation of the Jack Russell Terrier as a working breed. 

The club sponsors Fun Days and a sanctioned trial. Fun Days allow the dogs to learn about events at trials and socialize with other dogs and their owners. Fun Days are open to all small dogs and their owners.
