I some how lucked out and have 2 pups that don't jump! I don't know how it happened!
But my friend has a 150+lb wolfdog that used to jump up on you. She trained him to sit in order to get any attention, and it worked perfectly!!
I'd keep him on a leash and have people (with treats) walk in your house and tell him to sit and give him a treat. Give him a correction if he goes to jump.
