I have a five year old lab/border collie mix and a two year old pug/jrt we recently moved in with my boyfriend and the neighbours have complained that everytime we leave the lab barks constatly. This is unusual because in the other building we lived in, he was quiet whenever I was out, he would only bark when I was home!! I know this from the neighbours telling me how quiet they were whenever I was gone. I dont want any problems with our new neighbours and have been contacted and warned by management several times already. They are only left alone for a max of two hours a day and are walked four to five times a day for about an hour and a half. Any advice? Please help.
