Does anyone know of a Jack Russell rescue centre?  Have had a quick look on the internet but not found anything as yet. 

The dogs that many people call Jack Russells are not a recognised breed rather more often a type of terrier cross.  There are clubs for Parson Russel Terriers which are recognised and there are breed clubs for Purebred Jack Russells not recognised by the British Kennel club that keep a registry of some of the unrecognised lines.

I did a search on Jack Russel breed clubs in the UK

PARSON JACK RUSSELL TERRIER CLUB. Sec. Mrs R M Hussey Wilford. Tel No: 01905 821440

Excellent, I knew that it would be more complicated as they are not recognised - I shall pass the details on. Thank you for your help :)
