Crate training is the way to go. Some dogs catch on quicker. Here's a tip you won't find in a book. After he starts to catch on, If your leaving the house and really need the dog to shit before you leave, put some KY on a match stick (nonhead side) and stick it in his ass(not all the way). It will stimulate him and he will shit pretty quick. Sounds harsh but effective if you don't want to walk a minefield later.
