The term 'Jack Russell' is also commonly misapplied to other small tan and white terriers. 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). Each breed has different physical proportions according to the standards of their national breed clubs. Originating from dogs bred and used by the Reverend John Russell in the early 19th century, from whom the breed takes its name, the Jack Russell has similar origins to the modern Fox terrier. It has gone through several changes over the years, corresponding to different use and breed standards set by kennel clubs. Recognition by kennel clubs for the Jack Russell breed has been opposed by the breed's parent societies – which resulted in the breeding and recognition of the Parson Russell terrier.
