The Flagline Harness is a fast, light, and comfortable harness 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 nimble design good for all-day wear. High adjustability and easy on/off make the Flagline secure and accessible, giving dogs a little boost and a lot of freedom when the path ahead is anything but flat.

Love this harness. My pup is a Houdini and could get out of all the others we tried. The 2nd belly strap seems to work! It's cute. Its functional. Appears to be comfortable for my puppy. Easy to get on & off.

Flagline harness helps an older dog

Our 13 year old Golden has a lot of front and rear leg arthritis and so trouble getting up. The Flagline harness helps us give him the small "power assist" that makes it easier for him to move around.

Great Harness for my Shiba escape artisit!

The Flagline harness fit my Shiba great. And she has not been able to back out of it. I debated between this and the Webmaster, but after contacting Ruffwear for more information opted for this one. The information on proper fit is really helpful once you get it on your pup. We are still working on her being more comfortable getting the new harness on when she wants to got out, but that seems to be more of a Shiba thing than the harness itself. as there was only one harness she has had that she easily slipped on thus far. The security in knowing that she can't get out is worth it. Thanks Ruffwear!
