Let's talk about jumping up on people.

First, let's consider the dog's point of view. If your dog does manage to keep four feet on the floor, they might not be noticed! They cannot express their excitement at your presence! In contrast, if they jump on you, they will get noticed, whether you appreciate that or not. Sometimes any attention is better than no attention at all, so let this be a generic piece of advice: train your eye (and your response) to notice what goes right with your dog rather than focusing on what goes wrong.
