Hi, I think the renter needs to go, this is just not right it sounds like he disrespects you over everything and this is upsetting you and making you sick. First off I would raise his rent and tell him every time he disrespects you or the dog your going to raise it more. Then give him two week or 30 day to get out. In the meanwhile look for another renter. You can find someone maybe a little older and wiser that will act right. You have my support.
