You are smart to be looking for an excellent breeder instead of just a puppy. The breeder is everything.
I live in Southern CA and I took my time and saw a lot of pups and talked to even more breeders. The best place to start your search is at
www.YTCA.org
go to their breeder contact list and email some of them in your area and ask if/when they are expecting pups. These people have very few litters b/c they are going for quality not quantity.
Take the time to get to know some of the breeders here on YT and read all of the posts about breeders. There was a good thread not too long ago about different types of breeders. (on the Breeder Talk board)
If you find a breeder online, come back and ask for opinions
before you see or commit to a pup.
good luck and be patient!
