My upstairs neighbors have a new dog. It is driving me crazy. It barks for hours every single day. You cannot hear it outside their apartment, but you can hear it in my bedroom. It won't bark when they are home. When they are gone, all it does is bark. It has barked nonstop for the last 3 HOURS. I put a note on their door asking them to do something about it. It gives me a migraine. It is very high pitched yapping. Any ideas for what I can do to get this to stop before I go nuts?
