Flagline™ Dog Harness with Handle

lightweight, multi-use dog harness

Color

Selected: Sage 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.

    LOVE this harness

    I ordered this harness for one of my dogs after getting it for my other dog. I love that there is two points for securing the harness- one around the chest and one around the waist. This creates a much more secure fit for dogs with barrel chests and smaller necks (ours are American Pitbull Terriers). I had a hard time finding anything that my dog couldn't back out and slip out of. This one does the trick. The only chamges I would want to see: I wish the chest leash connection point was also metal for better pulling control (the reinforced material it has now works, but a metal loop would make me feel better) and the sizing for this one should also include back length and neck circumfrance. My dog was right on the fence with chest sizes and I ordered up, and while it fit around her chest great, the length was too long and the neck wasn't tight enough so I need to send it back for a smaller size. Overall- my favorite dog harness ever.

    Flagline harness

    I love this harness. My two Italian Greyhounds are pullers. I love the front leash attachment because that has solved the problem. Very sturdy and well made.
