I have had my Rat terrier for 6 years now and the strangest thing has happened recently. She is fully house broken and has been since we adopted her. Most recently though after the loss of our 6 month old puppy she has started to relieve herself inside. I don't know if maybe she is depressed at the loss of him or if there is something else that is wrong maybe physically.
She does go out regularly and has never done this before. I thought about getting another puppy for companionship to see if that would maybe fix the problem. Does anybody have any suggestions? I'm in real desperate need of help. I can't handle the messes anymore.
