Also, YT does have a Preferred Breeders list of forum members. It is currently only two and they are listed here.

With that said, I believe there are many more reputable breeders on YT other than just these 2 (although, these 2 are pretty great!). As others have said, ytca.org and akc.org and dog shows are good places to look. Specifically to support a fellow YT member/breeder though..just takes some researching around here and you'll see what you're looking for.
I agree, also - they are addicting!!! And I will be getting another (whether hubby thinks so or not lol).
