Abstract: This invention is designed for a person6 to interact7 with their dog8, or other animal, as a companion with the dog(s)9 pulling the vehicle at the dog's pace, with the dog in harness and still on a leash10. This allows the driver to maintain control of the dog at all times, including while the dog is pulling the vehicle at a walk, trot or run which would exceed most human's walking and running speed therefore giving the dog more freedom and exercise. This invention may also be used as a means to control a dog even when not pulling. 6 A person also denotes a “driver, owner, rider, trainer, handler, competitor, traveler' and the like.7 Interact also includes “recreate, exercise, compete, train, rehabilitate, transport, drafting” or the like.8 Dog as a singular will be used although more than one dog may be included.9 “Dog” is referred to here and includes any animal (such as horse, ox, goat or other) that may be used to pull a vehicle.
