Yorkie's wants to show there love and affection at all times.
My husband is not to sure still about the new arrive. We talk about this last night. I am sure that once you have give your yorkie a chance you will be surprised. Have you talk to your wife about this? Did you discuss bring home a new member of the family before your wife brought the dog home?
If not, this maybe one of the issue that you need to talk about to her.
I wish you the very best
