Carting is a sport also known as dryland mushing and is practiced all around the world, often to keep winter sled dogs in competition form during the off-season. The cart, or dryland rig, is attached to the dog in the same manner as a team to a sled. The training for running in a rig is basically the same as for sledding.
You will need: harnesses (X-Back recommended), gang line (or main line), tug lines, neck lines (for teams of more than 2 dogs), a reliable 3 or 4 wheeled rig with good brakes. Helmet and other protective gear is a must. Press here for more information about the equipment.
