luvdorkyyorkies, I undertsand where you're comming from and it's obvious you love your dogs. Can't ask for much more. The show circuit can be a zoo and I've seen dogs campained for best of breed in the Country, etc. Yorkie rose will most likely aggree (or correct me if I'm wrong) that only a very good dog wins, but the known breeders have the advantage.
All that being said it's a great experience for your dogs AND for you. Besides all that being said what better way to find a good stud or bitch? I'm newish to yorkies but I have experience with top show breeders of Dachsies (SLH), English Setters and PBGVS (Petite Basset Griffon Vandeen) and they were all good loving people. To love dogs so much you almost have to be a good person and most of the show circuit is full of nice people. At the top level it may get a little ugly but that you wont have to worry about... AT least for now
luvdorkyyorkies, it's obvious you love yorkies and breed within the standard, that's all I would/anyone should of you. I'm curios, are your pups papered? I'm guessing yes or showing wouldn't be an option.
