Thanks BB. I suspected as much. I only ever knew friendly dogs when I was growing up. In fact they had lives of their own. In the area of the small town I came from each dog was known as his dog name and the family surname. So we had the likes of Ringo Quinn, Judy Kilemade, Rusty Brannigan etc. They wandered as they chose to and our fellow, Spot, if he was out late and the back door was closed would go around to the other side of the house and jump up on the garden seat and tap at the sitting room window so we could let him in.
