Aggressive Goat Issues?

The best thing is to have him castrated. It will help. Goats also hate it when they are being held by the beard. Ten years ago we had a saanen buck about 375 pounds, with huge horns and a long beard. When a doe was in heat, he was dangerous. We had to grab him by the beard and flick him on the nose. Grabbing the horns is not the best thing to do, because they can overpower you before you get the chance to turn their head. So I do not suggest doing that. Bucks do not like being flicked or smacked on the nose. I have never heard anyone using mace on them though. And I don't suggest that either. You could also purchase a riding whip, that is short and has a folded piece of leather on the end, you can use it to smack the goat on the nose. It is not cruel if you use it for your defense.
