I'm no expert but from what I know, "fixing" calms dogs and cats. He definitely needs a ton of exercise but having him neutered should help with the humping at least. All animals should be fixed anyway if you're not a breeder for obvious reasons (overpopulation) but it will decrease the pets chance of getting cancer in the senior years.

My yorkie went through such a phase and the vet said it's what male dogs do to establish dominance in the household - so they don't feel at the bottom of the chain. We got him a stuff animal, affectionately dubbed "the hump bunny," for him to.. establish dominance over. A couple months later the bunny was retired and he's had no problems (read: no humping) since.

If you don't have time to get him the exercise he needs, a professional dog-walker is the way to go. Yes, they do exist! (I'm proof =)
