My husky slept next to my bed (but on the floor) until he was 12 months and we moved house and my mum decided he should be an outside dog because of all the fur in the house. I was dead against it and thought my husky would hate it. The first night he slept outside (he has a bed, a cane lounge, a blanket and a pillow with him) he cried, but after that he was fine. Now (when my mum is away) if I let him in for the night, he wants to go outside. He loves it! If your pup is chewing his matress, try and get him a bed with a steel frame (they are elevated off the ground). You can get them from heaps of pet stores and the dogs love them. Much harder for them to chew too!
