Perhaps spend a bit of time researching aggressive behaviour in dogs? Here's
a site to start you off and trust me, there are plenty more out there.

You could ask your vet to  treat him with an antiandrogen for a few weeks.
If his aggressiveness lessens, then castration will work.  If it does not
lessen, most likely the aggressiveness is a learned behaviour and might best
be treated  with behavioral therapy.  Best would be to have all the dogs
castrated, not just the one as he would then be on the bottom of the ladder
rank-wise  and the others would pounce on him, which in return would
possibly make him fear-aggressive.   So have a chat with your vet about
temporary trial on  antiandrogens (e.g. Tardak).

all the dogs should be castrated anyways.... neutered animals are more
pleasant as they don't have to deal w/all the hormonal stuff.  I found a
12yo redbone coonhound that was dog aggressive and kept trying to escape...
once I neutered him, he was fine.  No more trying to escape, fight, nothing.

With females, there are too many benefits NOT to spay.... they should be
spayed before their first heat.
All my dogs are neutered around 6 months old... or as soon as they come to
my home... same w/the cats.
It is easier
