I don't know if a lot of you would agree, but there are far more benefits of neutering your boy. You've read the pros and cons, you said. I'm sure you've read about reducing the risk of prostate cancer, tumors and infections. But would your dog be depressed? I think not, when they are neutered, their hormones that is responsible for reactions towards female dogs also disappears of course. They tend to spend time doing other activities as replacement for mating. Just be responsible enough to take the risks.
