Find a mentor in your area. It would have saved me heaps of disappointment, heartache and money if I'd done this at the beginning. I'm in a region that has precious few good breeders, so I have that excuse for not connecting properly early on. You're in a place that has lots of good breeders, so take advantage of it. The obvious place to look for a mentor is the YTCA and/or your regional breed club. I think you said your Yorkie is golden. If you're looking for mentorship in breeding non-traditional colors, you're going to find extra challenges in that. Some members of YTCEHB may be in your area and able to help you. Good luck. This is a fun hobby for those of us who don't mind spending all our time and money on it!
