I'm on my 2nd Neewa belt after running about 2000 miles with my old one. It's comfortable, dependable, doesn't hurt my back, and has opened up a lot of fun in running with my dog.
Dogs and I both love it! If you and your dogs love to run, definitely give it a try.
I have a 90lb Doberman who loves to pull, so I figured this belt system could be great. And I was right! I've tried other running systems, but this belt is by far the best. I love that it goes around my legs/hips rather than waist, so when my dog pulls it's easy to manage. I've actually found myself liking the feeling of the pull! I've also started using this system for walks because I've found it to be a much more enjoyable experience for me, rather than using a leash/collar or leash/more traditional harness. I'm recommending this system to all of my doggy friends!
Very comfortable and lightweight! Have another belt that sits too high near my waist and w/o leg straps...the Neewa belt makes a huge difference for your back.
