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.

First fully escape proof apparatus I’ve used with my canine escape artist!

I have spent five years using both a Martingale collar and another brand of harness at the same time (two leashes) with my adorable sweet gentle dog who sometimes panics. He is smart enough that when he panics, he knows to pull backwards instead of forwards and to scrunch his shoulders to try to get away from whatever scares him. Usually one or the other kept him from fully escaping. Once he got out of both completely. This Ruffwear Webmaster harness is impossible for him to actually back out of because of the elongated style and the extra strap near his belly. Plus, it seems exceptionally well-made, and he doesn’t mind wearing it at all. Nonetheless, I do still use it in tandem with the Martingale collar. Note: last week he panicked at some big noises and sat down and refused to budge, and I was able to use the harness handle and simply pick up my 42 pound border collie mix and move him forward a few feet until he decided he could actually walk on his own again. Pricey, but well worth it for the peace of mind.

Perfect fit, strong material

I bought this harness for my 18 month siberian husky Kadabra in size medium. I wanted something in-between beginner and expert as far as what i’d be using it for. I was using a kong harness and leash, but one morning the leash malfunctioned and after that I wanted nothing to do with their products. I found this harness, followed the size guide, and waited for it to come in. After minor adjustments it was the perfect fit! He seems comfortable, and it makes me feel good to know he’s in something safe and secure.

Web Master Harness - The best by far!

Been through several harnesses and none came even close to the quality and fit Of Ruffwear. Was told about Ruffwear by a fellow hiker. Zeke and I are so very happy. Bought the web master harness for my 120lb GSD and it fits perfectly and comfortably. Allows me to assist Zeke in and out of the car now without having to grab his back legs which are beginning to lose mobility and strength.

Husky’s outsmart harnesses...but not this one!

My husky lab had been named our Houdini because she can finagle out of her harness so easily. But not with the web Master Harness. The second section to click behind her ribs allows her to stay within the harness to keep her safe. We also purchased the bungee leash in which we love as well. Keeping me hands free while she has the ability to have a little more freedom. Great products and I love the colors!

Escape Proof

I picked this harness because I have a tiny beagle mix who is an escape master with harnesses. I love that it has so many straps to keep them secure- yet it’s very comfortable for them. Very well built. Super impressed.
