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.

    Chiweenie loves it

    The last harness she had looked like a crop top on our long-waisted baby. This looks better for sure, and the handle is fabulous. I never knew a dog needed a handle.

    Perfect for front leg amputee

    I discovered the flatline after doing some online research to find the perfect harness for my front leg amputee tripod.

    It is the only harness we have tried that stays in place. I love the design, colours and overall construction. It’s lightweight, doesn’t budge and is easy to get on and off. The multiple adjustment points allow for a perfect fit. Tilly is very agile for a tripod but I do avoid having her jump down from things so as not to pressure that one wrist too much. The handle is perfect for this. She already has two but I would love to get a third when colours come back in stock ☺️

    Slim line profile

    I purchased this for my grandpuppy since his other harness is quite a bit heavier and more material. This is perfect for him for the summer. Much lighter and yet he is still well secured.

    Love this harness!

    I bought my Flagline used from Ruffwear & it’s in excellent condition. It’s broken in but no signs of wear. This harness is highly adjustable & should fit a wide range of dogs within the size. It fits my big Doberman really well & appears comfortable.
