Ruffwear Flagline Harness for Dogs

Fast, light, and ready for anything - the Ruffwear Flagline Harness is built for dogs who are always in motion and handlers who need to keep up. Whether it's a backcountry scramble, an everyday trail, or a moment when your dog needs a lift, the Flagline keeps things moving.

Why the Flagline Harness?

The Flagline is designed around a nimble, minimal body profile that keeps dogs in their natural movement without interference. A load-dispersing chest and belly panel distributes weight evenly for comfortable lift-and-assist - making it particularly popular for dogs who need a helping hand on technical terrain, including tripods and senior dogs navigating challenging ground.

High adjustability and easy on/off buckles make it accessible and secure across a wide range of body types. The quick-grab handle on the back is always there when you need it.

What Makes It Work

Shell is 150D polyester ripstop with bluesign approved DWR and PU coating - lightweight, weather-resistant, and trail-ready. The lining is 75D polyester with heat emboss for a comfortable, debris-resistant fit against the dog's skin.

Buckles are bluesign approved ITW Nexus Mach 1 side-release. The front leash connection point is 87.5% UHMWPE (ultra-high-molecular-weight polyethylene) and 12.5% nylon - ultralight and ultrastrong. The back leash connection point is an anodised 6061-T6 aluminium V-ring. Made in Vietnam. Available in 4 colours × 5 sizes.

Suitable For

Five sizes (XXS through L/XL) cover a wide range of breeds. Particularly suited to draft dogs on trail, dogs requiring lift-and-assist support, and tripod dogs. The front and back attachment points make it versatile for both training and adventure use. This product is non-returnable due to hygiene reasons.

How to Use

Loosen all straps before fitting. Slip the harness over your dog's head, position the chest panel, and fasten all buckles. Adjust the multiple points of adjustment until the harness sits flush with two fingers fitting beneath each strap. Use the back V-ring for everyday leash attachment and the front clip for training or redirection.

Use the handle for lift-and-assist on technical terrain. Spot clean or hand wash with mild detergent, air dry.
