There are lots of ways to improve the fitness and conditioning of athletic and working dogs. This example is of the underwater treadmill (UWTM). The UWTM offers the cardiovascular benefits of the traditional land treadmill, but adds in the resistance of water to strengthen muscles and buoyancy to reduce the stress that gravity can put on joints during exercise. In addition to conditioning healthy dogs, it is used for the rehabilitation of injured or arthritic dogs. In this short video, Search and Rescue Dog Ben gets some exercise in the UWTM.
