For a few examples see below:

Above is a picture of my home made crush for administering to individual llamas. Llamas can enter from either side by removal of the horizontal rails which slide into place. They generally enter from this side by slowly pulling the gate in. They are then harnesses to the front horizontal and the other horizontal poles slotted into place to prevent the animal from moving backward, rearing or cushing. A professionally made crush designed by Annie Austin is soon to be manufactured andmarketed by Watertown Llamas and should be a welcome piece of kit for any llama owner.
