Izzie is adorable!!! I, too, may, when My SweetPea is about a year will get another yorkie.
I feel very much like you do.. about not knowing where or what!
But we lucked out because we have great mentors right here... and I've mentioned the best ones, I believe, at the start of this thread. It is very transparent that they are seriously committed to the betterment the breed and the sport. So I don't think anymore. I just follow, as a fully trust their advise. I trust My SweetPea's potential to them.
Thanks again YT mentors: DRAY (Debbie Ray)

, MARDELINE (Mary Lundgren)

, Teramom1 (Mary.. My SweetPea's godmamma as in The Godfather)

, and Kimberly

.. your website is awesome, and full of information that I did not have to purchase a book!
Thank you for your unselfish and generous sharing of personal experiences and the details & nuances of the breed which will make the difference in raising our yorkies the right way.
