Banjo is normally not a jumper. But of course there is one exception. When we're at the dog park if a dog is scared and jumps up in to it's owner's arms he jumps up on the owner to get to the dog. He means no ill will, he seriously does not have a mean bone in his body and thinks he's friends with every single dog he meets. But if a dog is up in it's owner's arms he wants to get up there with them.

Any tips on how to break this? He has a tendency to do it when I'm not within 5 feet of him and can't get to him quickly and of course no one listens to me when I shout across the yard just knee him off. They turn their backs which turns the dog away from him making him want to jump more to see the dog. And I can't tell all the other people to change their behavior to suit my dog. If all the dogs were on the ground at his level he wouldn't be jumping. He doesn't seem to grasp he's a little too happy and hyper for the more timid dogs and they don't seem to grasp he's a lover not a fighter.
