One of the best things to do is contact the breed club. They should be able to answer all the questions you have. The other thing is to contact the kennel club. They will be able to inform you of any litters. Talk to as many breeder and owners as possible, visit these dogs at their homes if yiou find people willing to let you. Any good breeder will sit 24/7 tell you about the breed and answering any questions you have.
Good luck
