The Omnijore Harness is a component of the Ruffwear Omnijore Joring System. The system is designed for any dog-powered activity such as skijoring, mountainboardjoring, skatejoring, bikejoring, or canicross. The harness fits your dog with five points of adjustment for a customised fit. A girth strap aids in training, and can be removed when your dog is accustomed to joring. The other components in the system are the Hipbelt and Towline.
