You posted another post where you said that your horse is not listening to you and you asked for tips.
i am just honest and i will say that even the calmest stallion can get dangerous if there is a mare that is in heat. You need to be very strict and very very systematic and consistent with your stallions education and if this is a problem for you even with other horses, I think it is a very dangerous decision to buy a stallion.
I've handled other people's stallions and it really depends on their temperament. You have to really know what you're doing and make sure you have good fencing and are able to keep them away from other horses
