Lightweight, Supportive & Built for Adventure
The Ruffwear Flagline™ Harness is designed for dogs who love exploring — whether that’s scrambling over rocks, hiking hills, or simply navigating everyday obstacles with a little help. It’s fast to put on, comfortable to wear all day, and includes a padded lift-assist handle so you can support your dog safely when they need it.
A load-spreading chest and belly panel helps distribute weight evenly during lifting, while the lightweight design keeps everything feeling agile and free-moving.
Secure, Adjustable & Comfortable
With six points of adjustment, the Flagline™ offers one of the most customisable fits in the Ruffwear range — ideal for deep-chested dogs, growing youngsters and slimmer breeds.
There are three lead attachment points to suit different walking styles:
a strong aluminium V-ring on the back for everyday use, plus reinforced webbing loops on the chest and rear section for additional control or training support.
The debris-resistant lining keeps the harness comfortable even on dusty trails or muddy adventures, while reflective trim improves visibility in low-light.
And of course, it’s all backed by Ruffwear’s lifetime craftsmanship guarantee.
Light Enough for Everyday — Strong Enough for Real-World Use
The Flagline™ is perfect for active dogs who sometimes need a boost — whether that’s into the car, over a stile, up a step, or across tricky terrain. The padded handle is easy to grip without digging into your hand, helping you steady or assist your dog with confidence.
Despite the added support features, the harness remains light, low-bulk and remarkably comfortable.
Matching Accessories Available
Pair with the matching Ruffwear Collar and Lead to complete the look. Why not add The Beacon light for winter walks.
