I would suggest putting her in a doggy daycare center when you go out on vacations. If you are just going somewhere fast and will be back in less then an hour, I would recommend a muzzle for her. Just make sure that she doesn't wear it to long! That might help with the barking problem. To help with the window sratching problem I would suggest putting her into a cage when you go out somewhere. Make sure that the cage has enough room for her to sit, stand, lay, stretch, and turn around!
