some dogs like to perform and be watched.

flamepony you say he goes 3 times? Is that the puppy wee wee, or puppy boo boo? If the former you might be getting into some territorial marking. It's hard to empty out the wee wees, especially in summer when their water intake goes up. Crating is the best bet at night. If a puppy boo boo, then keep feeding him earlier. Karen has a good point about the long walks. Exercise should make the colon go and empty out. Followed by no food in, no food out.
