The Jack Russell is a broad type, with a size range of 25–38 cm (10–15 in). The Parson Russell is limited only to a middle range with a standard size of 30–36 cm (12–14 in), while the Russell terrier is smaller at 20–30 cm (8–12 in). Russell was said to have prided himself that his terriers never tasted blood. This line of terriers developed by John Russell was well respected for those qualities, and his dogs were often taken on by hunt enthusiasts. 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 7 kg (15 lb).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.
