The Ruffwear Web Master Harness is a supportive, multi-use harness built for maneuvering and assisting dogs up and over obstacles as well as for designated working dogs. Thin, durable foam provides support without hindering range of motion and a platform for attaching patches and signage for working dogs. Five points of adjustment create a secure fit, while padded chest and belly straps make the Web Master comfortable for all-day wear. The preferred harness of many avalanche rescue dog programs, service dog handlers, and amputee dogs, the Web Master is a great collar alternative and ideal for hiking, scrambling, and mobility assistance.

Web Master Harness and Brush Guard - Other Uses

Web Master Harness came in handy. Originally purchased for our trip, but as stated in the Grip Trex review, our girl tore her ACL. We are using the Web Master Harness along with the Brush Guard for our disabled girl. She is not allowed to run, jump or twist, so we are using both items as medical aides. The harness prevents her from pulling to run and assists with lifting her in/out of the vehicle. The Brush Guard helps as it provides support for her underside as we lift.

I purchased this for my 9yr old dog, Bella, just for minor assistance getting onto and off of our pontoon boat. Little did I know at the time of purchase, a short later, I would need it to help her get up off the floor as she no longer has strength in her hind legs. Its been a lifesaver! Quality made product!!Thank you!

Our GSD Buddy has canine epilepsy. The medications he takes can inhibit his mobility. The handle on the harness is very helpful getting him upright after a slip or fall. It's very well made and fits our dog perfectly. Overall, it's the highest quality product we could find.

This is working perfectly for my little devil dog who likes to wriggle out of harnesses, take off and make us chase her. She hasn’t managed it with this one, and she looks very comfortable in it too. It’s well made and she doesn’t seem to mind it. A great buy.
