Felicity53, how I feel for you. I have a sort of similar situation in that my husband is mentally ill and although I don't think he would abuse my dogs, he uses them as a weapon against me. The other day I was almost at my place of work when he phoned me and said that my puppy had got out and he didn't know where she was. He casually said he would go and look for her when he had finished his cup of tea and got dressed! As you can guess I was frantic, then I heard her barking in the background! I work in the legal profession and I don't think your ex can take the dog but I would certainly be very vigilant as to her whereabouts all the time. Not at all nice for you
