Helen, hopefully there is someone involved with Westies on here, but I would advise your first port of call is the breed club. You should be able to get details through the Kennel Club. Breed clubs should only hold puppy lists from breeders who have ethical breeding methods and do any health checks required. Have you thought of going to Crufts next month and visiting the breed club stand or the Discover Dogs stand for Westies?
Good luck in your search, somewhere out there is a very luck Westie pup who will have you as his Mum.
