One of the basic skills of a veterinarian is the ability to position the dog correctly. "Rocky" was developed to teach this skill. Positioning is a skill that is needed all the time, whether for spaying or neutering, abdominal surgery, or x-rays. Positioning for spinal stabilization, supine or any other position is possible. "Rocky" provides a natural range of motion and also realistic resistance so that practice can be done in a simulation environment before the student works with a real animal. The mobility of the shoulders and hips is at 90°, the knees, elbows, ankle and carpal joints have the same mobility.
