Iris I too am sorry for this misadventure you are on. On another note, possibly the dog felt your husnabds animosity for you in his psyche. Sometimes even before we know what's what, our animals do. If he doesn't take his dog with him, see if it behaves differently after awhile once he's gone. The animal will be sad when he leaves but they have a way of adjusting to the mood of the home. Its worth a try to have a good, loyal watchdog. I hope it works out. I am a dog fancier big time, can you tell?
