I commend you for considering early in the puppy's life what is best for him. However, having said that, you should have thought about the time you had to spend with a puppy first. Yorkies are people dogs, moreso than other dogs. They want to be with someone. Also, I'd say there is little hope that your puppy will ever become housebroken and later, when this occurs to you, I imagine you would look for another home for him then. Believe it or not, this happens way too often with yorkies. Please find the little feller a home where he won't have to be alone so much. Preferably someone who can stay home all day and spoil him rotten!
