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. The Fox Terrier Club was formed in 1875 with Russell as one of the founder members; its breed standard was aspiration, and not a description of how the breed appeared then. By the start of the 20th century, the Fox terrier had altered more towards the modern breed, but in some parts of the country the old style of John Russell's terriers remained, and it is from those dogs that the modern Jack Russell type has descended.Many breeds can claim heritage to the early Fox terrier of this period, including the Brazilian terrier, Japanese terrier, Miniature Fox terrier, Ratonero Bodeguero Andaluz, Rat terrier, and Tenterfield terrier. Jack was dropped from the official name in 1999, and the recognised name of the breed became the Parson Russell terrier.In the late 1990s, the American Kennel Club explored the possibility of recognising the Jack Russell Terrier.
