Gelding question

I can't say anything about the gelding them younger with make them taller because we don't know how tall they would have been otherwise. I can say that the longer you wait to geld him, the more likely he is to develop the "stud" appearance; the cresty neck and large jaw typical to draft stallions. My Perch John was gelded at 4 and still has a couple of studly attitudes (though he is getting better). I plan to get my cross gelded no later than 1 year old. I could geld him now if I wanted because he has already dropped but I want him to have a little hint more muscle.

Gelding him will make him taller(proven that geldings grow taller and studs wider) and I would wait at LEAST until he drops to geld him.I would go with the vets opinion but wait until he looks completely dropped to decrease the chances of them not fully getting everthing.

Usually right after he drops--less risk and quicker recovery. If you plan to put him in training remember that he will need to recover and you don't want to interfere with the training because of this.
