The Dokkens Large Ducks Dead Fowl Trainer has uniqueness and purpose written all over it. Front and center is the hard-plastic head that is attached to the main body with a heavy cord. This innovative design is perfect in discouraging the bad habit of violently shaking a retrieved bird. A quick knock to the gun dog's snout helps curb this action. The hard feet encourage the retriever to secure the trainer in the soft middle, scent injected body area. Some of the best features.
