Graffy did this too when I brought Haylee home. Last night while I was cooking supper they started playing and chasing each other through the house. That was better than a Christmas present for me!!! I was worried that Graff would never adjust to her being here. Not to say they are the best of buds right now but we are alot closer to that than we were. Graff is my little abused yorkie that found me along side the road about 3 years ago and he doesn't like most people, but loves kids. He has more trouble with men than women so I figure it was a man that mistreated him so terribly. Hang in there I bet it gets better really soon.
