how old

Question
How old should my puppy be to get neudered? And does it help him from humping everything?

Answer
Males should be neutered from 6-10 months. I prefer waiting on the later side with boys to make sure their urinary tracts are fully developed, as long as there are no behavior problems to deal with.

No, neutering probably will not help with his humping, as he is expressing his dominance when he does that. Get him into some long-term obedience classes, and practice "Nothing in Life is Free" with him. http://k9deb.com/nilif.htm

Since yours, however, is apparently "feeling his oats" and expressing his dominance, I would neuter him sooner than later to try to tone down his testosterone a bit. Keep a close eye on him so that he doesn't try marking, too.
