Horse Rearing

But it all goes back to the horses hindquarters. The hindquarters must be free.

Make sure the horse is taught to lead up free (without resistance).

Make sure the horse is taught to flex his neck/poll from side to side and up and down (without resistance).

Get the horses hindquarters.
With the horse haltered, (for instance if you are on the horses right side) take the lead rope around the left hindquarter and with feel ask the horse to give in that direction. (The end result should be the horse moving the hindquarters around and coming back to face you).

One of the most common times that a horse will rear is when they are being asked to back up. This may be due to confusion or frustration. A Horse Rearing is a very dangerous situation. You should get the above exercises working for you on the ground before you try them on the horses back. Always remember to reward the slightest try from the horse.
