The crate is a good idea, although I have never used one. Lol. I have a friend that got one for her puppy. He views it as his safe place. The pet bed is absolutely a requirement. Eventually two. One in the crate, one in the room that you are in. His private bed keeps him off of the furniture. Or so the theory goes. It depends on your and the dogs personality. I am a push over. My last dog slept on her own heated bed on my bed. Yes, I let her. She cuddled better than the wife, snored about the same.
That dog was a chewer. She just chewed up squeeky toys. She would rip the guts out, and chew that up too.she chewed up at least one dog bed. The wife's current dog doesn't chew anything. He likes to play tug of war, so a rope is good for him. You will end up with a lot of stuff that he doesn't like, and the rest will be destroyed.
Otherwise, dog food bowls, water bowls, maybe a blanket or large towel and a cleaner with odor control while this house and toilet thing gets sorted out.
