Hello everyone - just an update - the delivery driver does not seem to have reported us to anyone, as I have had no letters or visits about the incident....we immediately put a wire letter box guard up as I just could not risk anything like this happening again (not easy to fit as we have mouldings on the door, but with some tin snips and imagination it's secure) and after a few days of flying at the box when the mail comes, the dogs now hear the post and totally ignore it, not even going to check the box out - thanks again for all your replies, they certainly helped when I was at my most upset about it all
