The patented Dokken Diver will teach any dog how to chase a diving crippled duck. A must for any waterfowl dog. Begin by reeeling a short distance underwater, let the Dokken's Diver surface. When your dog locates the Dokken's Dive give a sharp jerk on the rod to release the dummy. As your dog's confidence grows, increase the number of dives and the distance under water. Your dog will love this practice, and you will recover more ducks.
