You can also go to
http://ytca.org/. Exhibitor/breeders are listed there by state. There are several in Ohio. Like they have said, going to shows is a great help. Other than just being able to look at what's in the ring, you get a chance to talk to the breeders and they are usually quite willing to talk to you (if you approach them when they're not busy getting ready to show). Finding a good mentor IS definitely of major importance. After looking and studying different lines and deciding exactly the "look" I wanted, I was very fortunate to find both, a beautiful show puppy and not one, but two mentors! It may take a while to gain their trust as good, reputable exhibitor/breeders have learned to be VERY cautious, but it's well worth the effort it will require. Good luck in your search.
