I'm sorry about your possessions, but there just that. There replaceable. The dog sounds board. It needs a job. Summer vacation is just around the corner. Try spending some time with the pooch. Find something it enjoys,like catching bugs or chasing a stick. Try to get the dog to put it's efforts toward something that's less destructive. Let the dog know it's doing a good job when it's catching bugs,or what ever. Use kind words & a gentle but firm hand while training. Once the dog trusts you again. Most dogs just want to please there master. I have a lab rottweiler mix that turned into a great chicken/duck herding dog. It just takes a little time. Just like children they must be taught.....Good luck
