Your Dad must be a very unhappy soul. I can't imagine NOT loving animals, they make me laugh & smile everyday. AND I also can't imagine not supporting my daughter with her new baby. I hope his heart changes because that is sad. If it were me, I would have just TOLD him what I was doing and said, if I can't bring her, I will have to figure out other living arrangements. I am sure he would not want that. I have a very demanding Father, but I have learned to tell him NO and now that we are adults, we are equal. I also demand respect and privacy. You can love your Dad while making your own decisions in life, so dont let him control you forever. (speaking from experience). I love my Dad, but we have such a better relationship now that I am older and he knows where I stand.
I would think the breeder would be able to keep her with no problem. I hope so anyway, Yorkies are wonderful! I hope it all works out for you.
