Sadly I have 2 barkers. They will come out of a dead sleep barking when they hear a dog bark (either outside or on tv) or a doorbell on tv makes them mental. Also anyone who DARES to walk by my patio or my front door will hear it from them! This is hard to avoid considering I live in a townhouse. I've gotten written up twice by my condo association for their barking. I have started to play music at a decent volumn during the day while I am at work to drown out the outside noises that will get them barking. I think its helping bc its been about 4 months since Ive gotten a letter from my association. Pretty good so far!
