Description & Size guide

The Ruffwear Double Back Harness is an item of dog equipment that will serve even the most rugged of dogs. Designed for the extreme outdoor pursuits and with strength, safety and comfort in mind this really is the ultimate dog harness. We love it.

This harness is safety rated in strength including both the comfortable webbing and aluminium buckles. The Ruffwear Double Back Harness is, in its entirety, strength-rated to 2,000 lbf or 8.9 KN. In addition it includes four strength-rated, anodized aluminium lace-back buckles for safety and durability. Then add strength rated webbing, adjustable martingale and tie in point, which all combine to keep the dog safe and secure whatever his activity.

Because this dog harness is designed for safety and strength Ruffwear have, as usual, ensured the ultimate comfortable wearing experience for the dog. The design includes belly support, adjustable frame and leg loops for steady weight dispersion. As a handy addition the leg loops can be tucked away for increased mobility during approach.The Double Back Harness is specifically designed for rugged sports including climbing, mountaineering, and canyoneering, also perfect for belaying or simply helping dogs up and down steep and rocky terrain. This is an adjustable strength rated item of dog equipment with a superior design specific for lifting and lowering a dog in exposed areas.

We believe that our dog’s, and yours, are valued family members so if you are taking your canine into a tight spot he deserves the most comfortable, safest, dog harness that you can find and here it is.
