I've little to say that everybody else hasn't said already. Crate 'im. One question, though: do you mind him sleeping with you, or not?
I'm always perfectly happy to have a dog in bed (of course, I'm also not married). So, I just crated my dogs in my bedroom. Yes, I do realise how much racket that entails, but it also gives the desired results. You crate the dog for however long it takes him to learn to sleep through the night. After a new nights, he gives up howling. At the end of it, he's perfectly happy to crawl into bed with you and still leave you alone (crate for a night again if correction is necessary), and equally happy to sleep on the floor/anywhere else that gives him his own space and you yours.
