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.

No good size to be found

The design seems great. However, we bought ‘extra Small ‘ for our Jack Russell, whose widest girth measures 21”, and the size chart indicates extra small should fit, but it was uncomfortably tight even with all straps fully extended. We returned it and purchased a ‘small’. When the small arrived it was not usable as the rear strap crossed our poor dog’s *****. It too has been returned. It seems there is no size that fits our dog. Quite disappointing.

Size didn’t work out, dog is uncomfortable.

We bought a small for our dog, which was well within the sizing chart, but it’s too tight. It pinches his hair, and he seems uncomfortable in it. We tossed the label and dog hair was on it, so there was no choice to return it. Be careful - don’t remove the label before trying it on your dog, and make sure your dog is clean and brushed so you have a chance to return it. The return policy is probably the most disappointing part of Ruffwear.

Webmaster Harness

Great fit, easy to use. It has made a real difference to our three legged border collie who now has better support from the harness and less strain from a traditional lead and collar as walking is harder post amputation of his front leg last year. Love the handle on top too which gives greater support over obstacles or if he’s standing still or tired.

Very secure

Got this as a replacement after our Front Range harness bit the dust (aka harness loops tore). Impressed with how secure it fits him - no backing out of this! Con is that it is more complicated to get on husband has taken to walking him on the collar rather than taking the time to put this on because this one is less convenient to put on. Also, it would be great if this had a front lead option!

Best harness ever

My dog kept backing out of her traditional harness. Spent the money on a webmaster and haven’t had any problems since. Love it so much I am about to buy another one as a spare
