The small ducks are perfect for training the puppy and getting him hooked on ducks. The Dead Fowl Trainer body is made of a soft, natural-feel foam. The free-swinging head and feet are made of a hard plastic. This feature insures that a secure body hold will be the dog's preference, avoiding the hard head and feet. Because the body is a foam material it will not sink, even when punctured. With natural dead bird weight and internal duck scent, this training aid is a must for your program.
