One of a veterinary surgeon’s fundamental skills is the ability to position a dog correctly. "Rocky" was developed to teach this skill. Positioning is a technique that is required constantly, whether for neutering or spaying, for abdominal surgery or for X-ray imaging. Positioning for spinal stabilisation, dorsal recumbency (lying on the back) or any other position is possible. "Rocky" offers natural mobility as well as realistic resistance, allowing practice in a simulation environment before the trainee works with a real animal. Shoulder and hip mobility is 90°; the knees, elbows, hock and carpal joints have the same range of motion.
