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.

Web master harness

We have 2 small dogs. Our chihuahua can slip out of regular harnesses and we currently live in a condo without a yard so need to take them out on a leash to go outside. Our chihuahua could pull on his leash and slip right out of the traditional and vest harnesses. The last time he did it (even with T-shirt over harness) I got online and researched and found this one. The xxsmall fits our 9 lb chihuahua perfectly. It works. With the extra clip under his belly it hold it in place and doesn’t get in the way of body functions. We like it so much we got one for our bischon mix small fits and he is about 14 lbs. I watched the video to figure out how to measure. These are higher priced but so well made. Love this product. Great job ruffwear

Slightly harder than expected.

I was surprised at how “hard” this product is. Because it is not soft and movable, it appears more big and bulky. My dog did not like it in the beginning but now tolerates it. On the pro side, it is the first halter that he has not yet escaped from (he is a cattle dog).

Great harness strong and sturdy

I have a Tripod that is a 6 month old Boerboel missing the left front leg at birth. I researched many brands and many types of harnesses as the handles and grip are very important when it is a front leg missing. I love the strength of the material and the way the seams are stiched so tightly. The handle is fabulous! Love the ease of being able to assist my dog in a more natural way for both of us. The only issue I have and only because she is a special dog (Tripod-front leg missing) is the chest piece. I cannot lift the chest piece over her head to get it off as she is having surgeries to save the front leg. I am going to attempt to modify it so it has some sort of system to allow for it to be completely removed without going over head which we cant do. Great Harness, strong, lightweight.

First harness my dog hasnt slipped out of

My dog is a total Houdini. She is a 10 year old Rottie that climbs ladders into windows, slips out of any harness at will, etc. I got this harness to see if I could lift her in case she fell off the dock, I can lift her in it, and she doesnt slip out during walks or on the leash at all anymore. The Vet even mentioned how he liked it.
