I have heard great things about Linda Bush in Buena Park, CA, I cannot think of the name of her website. She has been breeding for over twenty years here in CA and gave me some support when I purchased a very sick yorkie from another breeder. Darn, I wish I could think of the name of her website, I also looked at a yorkie site here in Anaheim today, small breeder of about 5 years. That web site is
www.mypetyorkie.com, you could check out the references that they give. Good luck, stay away from puppy mills and brokers, I have had enough heartache from one here in SOCAL to last me forever. If you want the name of teh guy to stay away from, pm me.
