answer:Tell him to hang up his clothes, problem solved. And personally, if I had a boyfriend who was threatening to leave me because my dog was having a problem, I would get rid of him fast. His dedication to you and the relationship must not be too deeply invested. Has your usual routine of walks, trips outside changed since you have moved? I had a dog who when I moved to a new place, lived in the car for almost 3 months. She refused to come into the house even though the other dogs moved right in. She ate in the car, went for a walk and then returned to the car. This was obviously not an ideal solution, but I was in an area where it was possible, it was summer, she was an old dog so that is what I did. Point being for an older dog a change of venue can be difficult. I believe in letting a dog know they are doing wrong, even after the fact. When the dog misbehaves, show it the crime scene and give it a verbal dressing down, then take it outside. Is it desexed, male or female? Have you eliminated the possibility of a physical/medical problem? If so, use common sense in correcting the problem.
