Overtime your pup will anticipate this scenario and start to offer «calm» behavior on his own; typically SITS — until then anticipate a «jumping dog» and be prepared to have him sit BEFORE he has a chance to jump, or ignore him and walk away if he jumps up because you missed the chance to request a SIT — Pay attention to your puppy at all times, when he naps you can take a break to get other things done and then prepare for his
awakening once
again — then the
process of training starts all over and becomes a cycle you must repeat, and your puppy will continue to learn good healthy habits to be proud of once he grows up into that delightful adult dog you envision.
