Rearing, in my opinion is the most dangerous thing a horse can do. These methods to me are not cruel, cruel is locking a horse in a stall for 3 days without feed or water. Cracking an egg over a rearing horses head is harsh, but maybe a neccessary evil in my opinion. People say they have horses that rear. And I do know there is such a thing as an occasional rearer, but when you have a horse that is a chronic rearer, you have a very dangerous animal. Ruling out pain, saddle fit, and fear leaves a stubborn ornery horse. I know, I have one. And I love him dearly. But rearing is dangerous. Just my opinion.
