Today, Maru, 9-month-old Shibainu, played with my 6-year-old daughter. Maru was so kind that he didn't bite her eventhough she was a little bit naughty. They are probably about same age because dogs grow faster than us. My daughter is an only child in our family but Maru has become her brother since he came home. I think it makes my daughter grow faster that is really good for her. Now I have a good daughter and a son, and lovely my wife.
