Since he's 2 or 3 years old...go for it. Our vet always waits until they are 6 months old because he doesn't think it's good for the dog to do it any sooner even though that's the current belief that it's ok to do it at 8 weeks. We only have 2 un neutered animals and that's because they are too old and they were too old when we got them. Good luck and keep us posted.
