I don't think a dog is ever to old to housebreak, I do believe that crate training is the easiest way to go with puppies but i'm not so sure how that would work with an adult dog, especially one that probably doesn't want to ever see a crate/kennel again. I'm sure you will get lots of wonderful advice here.
