F.C.I.ís CLASSIFICATION: Group III (Terriers); Section 1 (large and medium sized Terriers); Subject to a working trial

FCI-Standard No 339 of the Parson Jack Russell Terrier


The promoter of this breed the Reverend John (Jack) Russell was born in 1795 in Dartmouth, Devon. He became a Clergyman and for most of his life served in the parish of Swimbridge, Devon. An experienced horseman and great huntsman he became passionately involved in the breeding and selection of terriers. In 1873 The Kennel Club was founded and he became one of its early members. He died in 1883 at the great age of 87. It was while studying at Oxford that he bought his first terrier, a white wire-haired bitch with head markings which closely resemble the standard of today. Jack Russell undertook a number of crosses between different working terriers, self coloured and parti-coloured types. His intention was always to improve the aptitude for hunting without too much regard for a uniform type. This tradition, crossing with other breeds of terriers continued until later times. He also attempted to cross the breed with other breeds of dog but the progeny did not correspond to the ancestral type of Jack Russell, these endeavours were disappointing and were abandoned.

From the end of the Second World War, this breed enjoyed increasing popularity on the European continent, particularly with hunters and horsemen. On 22nd January 1990, The Kennel Club (Great Britain) recognised the breed and published an Official Interim Standard under the name of the Parson Jack Russell Terrier. The FCI in its turn accepted this breed to its provisional list on 2nd July, 1990.
