The YTCA website is one starting point. You can also look for breed and conformation clubs in your area. Go to the AKC website and do a club search
American Kennel Club - Club Search and Directory
Your area should have some good clubs near by. Those clubs will list a breeder referral person that can get you started in the right direction. It is well worth the trouble to do a good investigation in order to get your dream pup.
A pup should be a family member for many years to come so be particular and do your research. Don't support breeders that devalue the breed.
