Well for the past 3 days trinity has started barking in the very early morning hours. Usually at 3am and then again at 7am. Its driving me crazy. She has never done this before until now. I have tried a bark collar in the past for her barking in the backyard and ended up having to go with a muzzle because the bark collar lost its effect on her after about 4 days. I don't want to have to put a bark collar or muzzle on trinity all the time. Just to let everyone know she is doing this barking inside. How do i get her to stop?
