There is a UK society and breed registry :

Some friends have a wire-haired teckel. She is a great character and fits in well with a mixed group of springers and labs. As a breed they seem a good alternative to a working type terrier as a pet/worker. They have apparantly been used for a variety of sporting purposes, although in the UK, most seem to be used for trailing deer.
Obedience seems to be a bit 'hit and miss'. Getting them to come back in 'gamey' areas can be a little problematic! ;-)
