try www.champdogs.co.uk - if KC registered you can put them on the Kennel Club puppy register too and most breed clubs have someone who holds a puppy register for anyone wanting a puppy.
I have a weimy, she's great really easy to train and does tricks! Did have a dog weimy also but he was so different, a bit stupid but so loyal. well weimys love to be around people and really do bond.
My weimy is 2 1/2 and we had a litter of pups earlier in the year, hope to do it again next year as she loved it, she had 7 and all were big healthy pups.
I advertised on epupz and all had deposits by the time they were 7 weeks old.
