That is a wonderful story. I can relate to it too. Jada wasn't abused or anything, but she is a retired breeder and I don't think she got very much one on one attention. She wouldn't play with toys or anything either. I bought her a loofah dog for christmas and it was like a light went off for her. Now it is her constant companion and we play every night with it. She runs and I chase her and I could have cried the first time she actually realized what playing was. I am so tickled for you and Boo that he is realizing that he is in a forever home and has the security to just be a pampered little boy.
