<P> Following Russell's death, the only people who made serious efforts to continue those strains were two men, one in Chislehurst with the surname of East, and another in Cornwall named Archer . East, at one point, had several couples, all of which were descended from one of Russell's dogs . The type aimed for were not as big as the show Fox terrier and were usually less than 15 pounds (6.8 kg). </P> <P> Arthur Blake Heinemann created the first breed standard and, in 1894, he founded the Devon and Somerset Badger Club, the aims of which were to promote badger digging rather than fox hunting, and the breeding of terriers suitable for this purpose . Terriers were acquired from Nicholas Snow of Oare, and they were likely descended from Russell's original dogs, as Russell would probably have hunted at some point with Snow's hunting club and is likely to have provided at least some of their original terriers . By the turn of the 20th century, Russell's name had become associated with this breed of dog . </P> <P> The club was later renamed the Parson Jack Russell Terrier Club . Badger digging required a different type of dog than fox hunting, and it is likely that Bull terrier stock was introduced to strengthen the breed, which may have caused the creation of a shorter legged variety of Jack Russell terrier that started to appear around this period . At the same time that a split was appearing between show and working Fox terriers, a further split was occurring between two different types of white terrier, both carrying Jack Russell's name . Heinemann was invited to judge classes for working terriers at Crufts with an aim to bring working terriers back into the show ring and influence those that disregard working qualities in dogs . These classes were continued for several years by various judges, but Charles Cruft dropped the attempt as the classes were never heavily competed . Following Heinemann's death in 1930, the kennel and leadership of the club passed to Annie Harris, but the club itself folded shortly before World War II . </P> <P> Following World War II, the requirement for hunting dogs drastically declined, and with it the numbers of Jack Russell terriers . The dogs were increasingly used as family and companion dogs . Further crossbreeding occurred, with Welsh corgis, Chihuahuas, and other smaller breeds of terrier . The offspring of these crosses became known as "Puddin' Dogs", "Shortie Jacks", or "Russell Terriers". </P>
