Hydrotherapy or underwater treadmill therapy provides an unique advantage to the rehabilitation program.
The resistance of the water increases muscular work as they walk on the treadmill, and can improve gait mechanics by the nature of the water resistance.
The bouyancy of the water allows dogs to be able to exercise with less stress to the joints, letting dogs that are arthritic or overweight get much needed exercise.
Dogs that have undergone disc surgery and cannot yet walk on land, can often walk in the underwater treadmill. It provides much needed walking practice as well as encouragement and independence that they would otherwise not be able to obtain.
