I'd also neuter him ASAP.
I had a friend who never neutered his dog (Max, a min pin) because he didn't think it was necessary. Poor Max had an enlarged prostate and testicular cancer when he was about 11 or 12, which is relatively young for a min pin, and had to be put down.

My friend regretted it ever since. He said if he had to do it all over again, knowing what he knows now, he would have neutered him.

I think neutering is good not only for health but for happiness. I can't imagine how it would be like being a dog and having urges but never being able to satisfy those urges. You neuter/spay your pet and they stop getting urges and become happier.
