Terri,

I would have to agree with Catrynfox. You also have to ask yourself is he really that special (bloodlines,etc.)to want to keep him a stallion. For me even over bloodlines is a sallions temperment, if he doesn't have the right attitude then maybe he's not worth keeping a stallion. If you do keep him I would look into getting help. But gelding him now will stop anything from sticking around. The younger they are the better they recover from the gelding process. Good luck in what you decide.
