You shouldn't be breeding Yorkies if they are not of standard, and been genetically tested and health tested 100%... CKC is not a very reputable place to register your dogs as anyone can do it. AKC, while not always perfect, is much more reputable. Your boy is over standard (up to 7lbs) and you should definitely not have such a large male impregnating such a small female! That could be disastrous for the girl, or life threatening. I don't think your dog looks mixed, just not a properly bred or standard Yorkie -- but that's ok... I love the big guys! My boy is so far from standard! Keep them as your darling pets and not breeding!
