I would urge anyone looking for any breed of puppy to contact the NATIONAL BREED CLUB, which you can find at
http://www.akc.org.
Each club generally has a breeder referral person, or a list of breeders that you can look through to find someone in your area.
Not ALL who are members of their National clubs are great breeders, but it is a good place to start.
ANY breeder should be asking you questions, requiring spay/neuter of any animal sold as a pet, and selling with a signed contract.
If this is not made clear from the very start, keep looking.
