Guest this si a breed that has a very small number bred as they are not the most popular as a pet. the breederws I know only breed about once every five years when they have puppies booked, and some will put to sleep at birth any excess puppies as they are not the easiest breed to find suitable homes for.
I would suggest you contact the breed clubs and get a list of breedrs and ask to be put on teh waiting list of one whose dogs you admire. You are very unlikely to find soemone with a litter juts waiting, but may be lucky and go on the waiting list for one being planned.
