Outdoorsmen and women trust SportDOG Collars to get their hunting partner up to speed for hunting season. Hunters are always looking for a better way to train their dogs, and the SportDOG Field Trainer lets hunters train in the field with up to 500 yards of range. The SportDOG 400 S Field Trainer gives hunters the chance to train two dogs together by adding an extra collar. The SportDOG 800 Wetland Hunter has a small receiver for easy portability outdoors. SportDOG Training materials such as whistles and dummies can be valuable tools in a dog's training.
