What's the best way to get "pet stink" out of their beds?

What began as a worry that our sewer was backing up ended with my "unpleasant" discovery that it was just my dog's bed fermenting in the dyer. Before today I don't think I'd ever been punched by stink. In this case I don't think the bed was dried fully and it started to mildew which only added to the pungent stomach churning bouquet. So I was hoping for some home remedies to kill whatever unholy mess is making it smell like that, or some products you good people have discovered has worked like a charm.
