Hi guys. I'm new to breeding. I'm trying to give everyone in my family a yorkie. My first question is how do search for their bloodline. I have the name of the dam and sire but don't know where to look. Second question is how will i know if my precious is pregnant. she went int heat on may 3 and she was invloved in fornication about 4 times since then....is that good or bad. Do I need to get a book on breeding or can I find everything online. Please help guys. pics coming soon
