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.

Reviews Summary
Customers say this harness is exceptionally secure and escape-proof, with a practical handle that proves invaluable for lifting and assisting dogs. The lightweight, adjustable design fits various body shapes well, from deep-chested breeds to long-bodied dogs. Many appreciate its durability and comfort during warm weather. The double-strap system provides extra stability, while the handle offers support for both active and senior dogs. While most love the fit, some note it runs slightly small and wish for more color options.

    Xs size worked great

    Just received the harness today. I have owned a couple of other brands. This fit beautifully on him. Even with using a long training leash the harness stayed centered in the middle of his back. Excited to use this out in the woods soon.

    My 13 y/o dawg thinks he has a magic carpet

    This harness was a graduation from the simple gentle leader harness. As our 70lb fritz got older, he required more lift from us. Well turns out this thing works because the dude thinks he has a magic carpet. He jumps out the back of the truck camper, turns out we are always there to catch him. He loves the extra boost. It makes activities fun.

    Saved Milo’s life!!

    Our little Milo is well and alive thanks to this harness and the handle on top of it. He is only 14lbs and a very large dog attacked him. I just had time to grab Milo by the handle and lift him up above my head. The other dog had no interest in me and the owner was quick at grabbing him and apologize. The other dog was leashed but slipped off his color when he saw mine. There is no way I could have lifted Milo so high and so fast without this full harness and handle. Thank you so much for this great product. - Isabelle and Milo
