I don't have a Yorkie-yet- but do have 6 lb and 7 lb toy poodles along with a 150 lb Mastiff. The Mastiff was "raised" by the poodles, and is so gentle and careful with them, that I do not worry at all about playing too hard. Our Mastiff plays tug of war with the poodles. It is hilarious and heartwarming all in one. She lays down and holds the rope in her mouth while the poodles shake and pull on the rope. When the Mastiff is sleeping (always on the couch) the poodles lay on top of her or curled up against her side. She always waits for them to get down before she moves. So, in my opinion, even if your new puppy gets bigger, if he/she is taught to be careful, it should be ok!
