Cani-hike and canicross are the most accessible harnessed dog sports. You will need a pulling harness for your dog, a multi-sport bungee line to attach your dog to you, and a canicross belt. Two options are available to you for this last item: single traction or double traction. The first option, the double traction canicross belt, is ideal if you have a powerful dog that pulls very hard or has back pain. It allows you to better distribute your dog's pulling force on your pelvis.
