My dog is a year and a half and very intelligent but has her moments. She is crate trained and is good about going outside to do her thing as soon as she is let out. The problem is later when either my room mate or I walk in the door when one of us is already home. She pees on the floor and slinks around like a snake. doesn't matter which one of us let's her out initially and who comes home later it is just an issue when the second person comes home. We both discipline and praise equally. She will do commands regardless of who says them. We've tried ignoring her letting her come to the person who just came home but she will still pee upon coming over. We've tried being excited when we come home but the same result occurs. Help please, this has to stop.
