I know I can't help, but Angus & Roxey are the same way, not the tearing up of anything, but Roxey tries to take Angus's toys, bones or whatever. He also used to let her do this, but now he gets really angry. I thought it was only because he was sick, but after hearing your story, maby we kinda have the same problem. He never wants to even try to play with Roxey, he just shows his teeth & growls. He still can't stand to be away from her, but also can't stand to be with her, unless she leaves him alone. I would like to hear what Carrie has to say.
