Last fall purchased a nine year old Paint breeding stud, nice disposition but was never taught any ground manners, was only used for open pasture breeding. We never get in his pen/yard without having hold of his head, he will kick. When leading him he is extremely pushy. When I take him out the gate to the arena he know he is going to be breeding, I actually need a tank to hold him back, leans on me so heavy makes my shoulders and back hurt. Using a stud chain, if I back him up or turn him in circles he will go to rearing and clawing the air, very dangerous. It is not possible to hand breed with him, we have to wait till he leave the gate to circle and then put the mare in the arena. Is it possible to teach this mature stud manners?
