I was just wondering if there is some way to find out what color the pups would be if the female is Blue & Gold and the stud is a Black & Gold, does it always vary? Should a Blue & Gold female be bred to a Blue & Gold stud, or does it even matter? What is the general rule of thumb for breeding for color? Is it just personal preference? Hopefully some of you experienced Yorkie breeders can help out with this, because I can't find anything on the internet.
