TWISTEP® is an instant, multi-use step that helps your dog get in and out of your Pickup Truck easily. It attaches to the hitch receiver of your vehicle and stores under the bumper when not in use. TWISTEP® provides your pet with lower-impact, lower-stress access into and out of a vehicle. Repeated jumping into and out of a vehicle can aggravate or even cause serious conditions like arthritis, leg injuries, back sprains and other spinal damage. And lifting a large dog into a vehicle isn't easy! TWISTEP® can help dogs of all ages get into a vehicle. Young dogs can avoid unnecessary stress on growing hips and elbows. Active dogs can appreciate a step up at the end of a long day of hiking, hunting and other outdoor activities. And TWISTEP® can help older dogs, who may suffer from arthritis and who can no longer enter a vehicle on their own. TWISTEP® easily swivels out from under the vehicle in a few seconds just when you need it. And it tucks out of the way under the bumper when you don't. TWISTEP® fits trucks with a 2" receiver hitch.
