I would say this dog is still just a pup, but you can still break him of bad habits. You might try not letting him jump up on trucks and people by keeping him on a long lead and popping it hard when he starts to jump. Or you could try a shock collar for the jumping, you'd just have to do it right and not overdue it, while still being consistent. You aren't bothered by him being hyper, I don' think, and you can't help that anyway until he is older, but you can teach what not to do when hyper....good luck. -MIKE
