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.

We have multiple of these, we always have at least one back up per dog, we have 5 harnesses total now. I truly wouldn’t use another harness on my skittish dogs.

Great Investment

I've used the Web Master Harness a couple times now and I can say I'm pleased with my purchase. It's definitely the most expensive harness I've purchased, but it seems to be well made and has a good fit on my dog. I'm only wishing I would have purchased the palisades pack since the bags are removable from the harness instead of having to eventually make that purchase down the road.

Awesome All Around

I bought this after my heeler wore out his front range harness because I wanted something with more options. He measures right between a small and a medium so I followed Ruffwear's advice and got a small. It fits him perfect, a medium would've been too long. I also bought the brush guard and got a small in that as well. The guard only fits because he is at the biggest settings on the harness, otherwise he would've needed a smaller guard. This harness is great in the car, super tough in the field, and I will definitely be buying a cooling insert as well. Another great product from Ruffwear!
