Soumen, Balou stayed with us because our daughter was on vacation. She often sat this way just looking out through the window. Perhaps she was thinking about the return of our daughter.
Anna-Maria, she knows a few commands and now and then she obeys them. But because it is not our dog we put no effort in her training. When we walk her, we don't have to keep an eye on her, it is the other way around, Balou is keeping an eye on us!
