Hi,
I think it isnt quite as simple as it might appear. You will need to take a lot of factors into consideration.
How confident is your dog, what kind of character does he have?
Can you in all honesty say that you can cope with an entire male if the bitch down the road is in season?
Basically, i would say, if it can be avoided, dont get him done. If you can 100% say that he wont be bred from accidentally, that he wont escape and get hurt in the search for a bitch, then dont get him neutered.
There are some very good reasons to neuter, but it CAN AND WILL change some dogs temperaments. If your dog is slightly nervy, or underconfident, neutering could result in a very nervous aggressive dog, simply because you are removing his testosterone.
If you arent prepared for this to happen, then you could be making some serious problems for the future.
That said, if you arent sure that you can keep your dog away from bitches, or that you can cope with an entire male dog, then by all means, get him done, BUT, be aware of the risks. Work on making sure that he really is a happy, confident and well socialised boy, BEFORE as well as AFTER the op.
Good luck
Em
