I just have to say Annie, that I feel sorry for your dogs. All of our animals are as much a part of our family as any of us are and while they are well trained and well mannered, I can't imagine doing most of the things you suggest to an animal I love.
Joanie, you have gotten some great ideas here. Mostly, put away the good stuff, have your son enjoy the love and company of a dog he rescued and has obviously provided an exceptionally loving home for. One of these days, unfortunately, he will be able to put the good stuff back on the bed and just wish his friend was still there to tear it up.
