I think it is wonderful that you are wanting to put your puppy's needs first. You have been given lots of opinions and I wanted to add mine. I have four Yorkies and I've had them all since they were babies. I can not imagine them being happy at all without all the interaction and attention we give them. They need that as puppies. I honestly believe that if you or your wife must work and at times be away in the evenings, it would be best to find a home where a puppy can have all the attention he/she can get. I do wish you the best in making your decision.
