A working dog needs a different type of harness to our fleece walking range. This includes dogs used for Sledding, Cani-X, Scootering, Bikejoring, Skijoring, and Tracking. Rather than loose lead walking, the dog needs to be able to pull into the harness so, for this reason , these harnesses sit further back on the dog. The most popular working harness is the X-Back which was invented in 1953 in Montana and has become the recognised standard for sled dogs around the world. Whether you are training a husky or malamute to pull a rig or sled for fun, or you aspire to win the Iditarod or the Yukon Quest, these harnesses are for you. These harnesses have been copied, but never bettered and are now available to mushers and enthusiasts in the UK. ZIMA X-BACK CLOSED CELL FOAM HARNESS.
