Personally, if I was not having any behavioral issues I would not neuter. I know I am responsible, my dogs do not even go out in the backyard alone, I would never allow them to run at large. The only reason I neutered my boy was the contract I signed with his breeder. I will make sure that is not an issue with my next puppy. I held out until he was 2 and I absolutely would not neuter until that age anyway.
If your breeder allows you to make that decision and you are certain you can keep your dog under your control at all times maybe you don't need to even worry about it right now. See how things go but definitely wait until the growth plates close and he has matured.
