How do i stop my dog from moving his crate when I am not home?

The crate I have my dog in does not have a trey in it. So he sits in the crate and some how he has managed a way to move the crate from the kitchen to the living room fireplace. And along the way he pulls in whater peace of paper or plastic he can find and rips it to shreds. He made his way to my blinds and tore them to pieces. I dont know what to do. I have twins on the way and if he keeps this up he has to go.
