Barking at the window.
We got Sheba, a female short-haired gsd, from a kennel close by us but we were all unsure of where she came from as the man who sold her to us had no information on her previous owner, so we knew nothing about her. She seems a cleaver dog after having her for almost 2 years, she can sit, lay down, jump up at the back door to open it then goes out to 'do her buisness' she has only 'done her buisness' twice in the house from when everyone was out from early morning and the door was locked but thats fine. But what she always does, is jump up at the front window and bark at anyone who walks past. Sometimes when nobodies even there. We have tried just asking in a gentle voice for her to get down, then we resorted to shouting but she still didn't come down. Sometimes she will come down on her own but other times she needs a little push (nothing that will hurt her don't worry) The reason im asking is that it's getting very annoying especially when people are on the phone.Any solutions?
