Hi there. I suggest that you should tire him out. Play hard with him, run with him, whatever you can do and then you should get some downtime afterwards when he is chill and relaxed. He's going to have all that energy until you give him something to do with it. Teach him how to jump for example. Use the command 'Up!' and teach him how to jump, like onto a bench, over a log. That should burn up some energy.
