Shock-absorbing bumpers that are adapted and configured to be attached to an interior wall of an animal hauling slant load trailer and positioned to contact the shoulder of an equine when the equine is driven forward by a deceleration or braking of the trailer. The bumper(s) are positioned to contact and restrain the equine shoulder allowing it to lean into it, thereby preventing the unnecessary extension of and stress on the animal's right front leg and hoof.
