The Flagline Harness is a fast, light, and comfortable body harness with a nimble design that keeps dogs in their flow, from scrambling in the backcountry to conquering everyday obstacles.

A handle and load-dispersing chest/belly panel make for easy lift-and-assist in a minimal design good for all-day wear. High adjustability and easy on/off make the Flagline secure and accessible, especially popular among tripods, deeming it the harness of choice for giving dogs a little boost and a lot of freedom when the path ahead is anything but flat.

    the perfect harness!

    my 6 mo. old pup Winnie has an oddly shaped body with a large chest and long torso so the additional adjustment points are super helpful! Winnie wears a medium even though she has a 24 inch girth as she’s still a growing puppy, but I was able to get this harness to fit her no problem. this harness does not shift as she walks and gives her enough room around the armpits that she doesn’t chafe. love the 3 leash attachment options, and we specifically chose the flagline for its lightweight material and handle on the back (super handy for when she’s hiking!) definitely the best harness by far for dogs with long or oddly shaped bodies!

    best harness I've ever bought

    The Flagline is just a great harness for tripawds, or those with 4 legs! Got one for our senior but healthy and active girl who had to have a front leg sarcoma amputation on 2/10. She's since all healed and the Flagline works great for her. It's really well-designed and made and lightweight, it goes on very easily with 4 snap buckles. Thanks for such a high quality product!

    Perfect fit and comfort

    Our Lily is a BIG, long, and powerful girl who loves to chase foxes, the occasional squirrel, and rabbit. We absolutely need a strong harness to walk her. We have been using your WebMasters very successfully for her first 5 years with us. With Summer approaching and the heat and humidity of NOVA, we decided to try your Flagline model - both have that much needed handle - to both hold her and assist her as she is getting older. The Flagline covers less of the width across her back, which may help with the heat. But we love its ease of putting on her and she seems to enjoy the openess around her legs. Plus it doesn’t move as much as the other when she walks. And those walks can be from one to four miles any given morning.

    Both harnesses are terrific and I wouldn’t hesitate to recommend them to anyone. Or buy either again myself!

    Best harness ever!

    This harness is really great! We got a size L/XL for our 93 pound dog and it fits perfectly. The pink color is beautiful, and the two sets of buckles make this harness fit really well if your dog has a longer torso. It does not rub around her armpits like the single buckle ones do.

    Our dog is not able to escape this harness. She has tried and she cannot.
