Flagline™ Dog Harness with Handle

lightweight, multi-use dog harness

Color

Selected: Lichen Green

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.

    It works great on my lab and gives me more options for management when he is learning how to walk nicely on a leash

    Finally the perfect harness!!

    My Houdini Aussie kept backing out of her Front Range harness, and the Webmaster was just too much harness. With help from a Ruffwear specialist we settled on the Flagline and it is perfect! Nice and light, and the third contact point keeps my slippery girl in her harness. An extra plus—the salmon color is beautiful! Job well done (again!) Ruffwear. Thank you!!

    Great for mutts & escape artists

    Our dog is a mutt with a funny build, and can slip a lot of harnesses. This one has given us enough sizing options to fit her comfortably while also preventing any more slip outs. It’s super lightweight which is a concern in our area during summer months, and I love having two connection options as well as a handle on top. So happy to finally have a harness we plan to keep!

    This is an awesome harness. The materials feel high quality and are easy to clean dust, mud and sand off of. The harness provides really great support, supporting the chest, ribs and waist/tummy of your pup if you were to pick them up using the handle. This harness has been especially helpful for my dog, who is missing her front leg. In other harnesses, the lack of support/straps around her chest and neck would make the harness fit more loosely thus making it less effective. The Flagline harness, however, fits nicely around her neck and chest. I attach her leash to the center clasp of the harness right at the midpoint of her back, and this offers most stability for her balance. If she tugs a bit, she will not be yanked awkwardly off balance. Overall, highly recommend this product. If I ever get another dog—I will be getting another one of these.

    Flagline dog harness

    Quality and super easy to put on and take off. Our dog gives it 5 paws. Plenty of colors to choose from. Three leash connection points and lots of sturdy st-st-stitching. Macy takes to this harness like a duck to water. So glad we saw the website for Ruffwear harness.
