very normal for boxer pups, they are off the walls. best thing to do would be to exercise them half to death lol, but seriously they need to expend ALOT of that energy. As they get older they mellow out some, but still an active dog.
I also have a Boxer she is just over a year . As everyone has said lots of walking her. I also have collar that i can use the noise the noise to keep her from getting in trouble. That has made a huge difference in the last week that have used it.
