My doberman is 19 months now and still intact. I wanted him to finish growing, especially since he's a bigger dog, before I got him fixed. Of course, this was a decision I had to make after figuring out if I wanted to (and could be) responsible for an intact dog and that's not for everybody.
Many puppies get neutered young and are perfectly fine. Since Diezel is a male you don't really need to worry so much. It's a quick and simple surgery and not anywhere near as major as a spay. Running around a little shouldn't harm him. I'd suggest lots of short controlled walks and mental games/training post-surgery to tire him out since you do want to try to keep him from being super active. Minimize the jumping too.
