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 the Flagline

    I love the flagline harness, I own six of them. They are lightweight, easy to adjust and so far have proven to be escape proof (been using for years) and my dogs find them to be comfortable. I really really wish Ruffwear would make a bright orange version of the flagline for dogs to wear during hunting season. I do have the bright orange webmaster, but it’s thicker and not as flexible and not as lightweight. My dogs don’t like it as much.

    Perfect for my Bichon

    I had another small dog harness but my dog was able to get out of it and was not comfortable in it. This one is adjustable to fit her perfectly and Is much more comfortable. I love that I can attach the leash on top or in the front. I use it just for our walks but I am 69 years old so this keeps my 18 month old dog from pulling me too much. The dog walker like to attach the leash on top and I attach it in front when I walk her.

    Love the harness as a whole…in dire need of more color options.

    This harness has been amazing for my boy! it has held up through use and abuse and looks almost brand new. i love it and will only buy ruffwear from here on out. but my dog has an assigned color like all my others and he wears the river rock green and unfortunately we are very limited in color options for this harness and that forced me to choose a color i am really not a fan of!

    Good choice

    We chose this harness because our dog is deep-chested, and her previous harness rode up her chest and rubbed against her armpits. With the third strap securing it in place and the straps positioned this way, the harness no longer rubs and twists very little. It feels sturdier and lighter at once. We've only had it for a week, so I can't say much about durability, but the material seems durable and of good quality.

    Fits my lean girl great + super features

    TL; DR: size Small fits my narrow 31-lb BC mix with a 23.25” ribcage perfectly; she is consistently this size in RuffWear items. REVIEW: I went to the store to buy the Front Range harness I’d been eyeing, but ended up so much happier with the Flagline harness! I’m glad I had my pup with me to try both in, as I was sure the Flagline would be too long for her. As you can see in the pictures, it’s not too long at all. I love that it has a handle for emergency lifts; it has a bit more length along her spine/ribcage, so doesn’t choke up on her armpits/shoulders; it has a spot for her safety light; is almost infinitely adjustable size-wise; and it is really lightweight, which is perfect for my girl. I would trust the construction for any supervised dog including pullers, but this is not a harness to leave on an unsupervised chewer (tho tbh any chewer can make fast work of ANY harness, so …). My pup can be worried/skittish at times, and this harness feels very secure and also lightweight enough that she doesn’t seem to worry about feeling “trapped” in it. Bonus, I LOVE this color—granite grey with pretty light blue webbing that looks great and makes the straps and clips visible against her black coat. I’ve been training dogs for close to 30 years now, and have literally vested thousands of dollars in “dog tack” for my own use and my clients’. I am consistently impressed by RuffWear ‘s designs and build quality, and the Flagline harness is my favorite product to date! (Katie-Bug…
