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.

Just what we needed...

My dog, Daisy, was a rescue. I didn't know much about her before I adopted her except that she was "scared." Every harness I've tried with her has failed. One time she ended up running across a busy, city street because she got out of her harness. I was at a loss until a friend recommended Ruffwear. We've only been using the harness for a few weeks as she had to grow into it a bit more. The reviews I read through are correct in that the harness does run large. I'm glad others posted that otherwise I would have purchased a Medium instead of a small as Daisy measured right on the cusp of being a medium by measurements. I had to tighten the harness a lot to get it to fit properly. Not only is the fit great, but Daisy appears more confident when she is in it. She doesn't panic like she used to (she'll still get scared) but she won't try to run away anymore. It might be the snug fit or the support of the harness, but it has been doing wonders for her. The only downside I could think of would be the limited colors. This harness is well worth the money!

Dog Harness

I love it! It is secure on my dog and I don't believe he can slip it off like he has done with other harnesses. It is easier to walk him too, he does not practically pull me off my feet as he does with other harnesses. It is also easy to put on even with two buckles to secure.

Excellent harness

My dog is a recent hind leg amputee and this harness was highly recommended by several different sources. I like the handle and how it allows me to give my dog a lift when she needs it. However I was really disappointed that I have to lift her front leg to put the harness on. I’ve found a way to support her hind end while I lift but it is challenging and my dog is not a fan. I wish the harness had one more buckle on the top to eliminate this issue. I bought a medium and my dog is a 50 lb boxer/lab mix. No issues with sizing.

Awesome harness

I bought this harness and the stretching leash, and they are awesome. Great quality, fitting for the harness was perfect and the night reflection on the harness added a great little touch.

Escape Proof - FINALLY

We use our other RuffWear harness on a consistent basis and LOVE it. However, we recently began participating in an activity that involved items our pup could not “stay put” when needed for. And he learned the “back out of it” trick. This webmaster harness is just what needed to keep our deaf pup safely tethered to us during these outings. And until we can learn some better impulse control this will be our go to harness. We are never disappointed in the products we get from RUFFWEAR - top notch, great quality, and exactly as advertised. Getting the life vest for summer boating trips next - already know we will be as satisfied with that as our previous purchases just by comparing it to other options out there and knowing what we’ve received from this company in the past.
