The Ruffwear Web Master Harness is a secure, 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.

Nice product

Fits snugly and circumferentially is the correct size. It does seem a little short in length on my dog's frame. Works fine, however.

Unparalleled quality.

This harness is solid! Stitching is perfect. All the pull points are oversewn beautifully. She is very comfortable in it and it looks very attractive on her. Thank you for providing a superior product over all the others. I have other harnesses but this one is far and away the finest. Again, thank you for real value.

It is by far our favorite harness. No complaints.

So far so good!

I regularly take my small dog on technical scrambles, and now I can help her onto ledges that she cannot jump onto by herself. The only downside is that it is pretty stiff and bulky which inhibits her movement when hiking. I hope it will break in with time. :)

Wish I had found this earlier for all my dogs!

Both our German Shepard’s love their harnesses! I wish we would have had these for all our other dogs. It makes such a difference when walking our 90lb+ pup. Gives us much more control and the handle is wonderful! Thank you for an amazing product!
