The Flagline harness by Ruffwear is a game changer for three legged dogs. It’s the leanest and lightest harness yet, and the only Ruffwear harness that slips over your dog’s head making it the easies to put on front-leg amputees – regardless of which leg is missing.

The Ruffwear Flagline Harness is a Game-Changer for Helping Tripawd Dogs

The Flagline is an incredible new option for Tripawds. It is the first Tripawd support harness by Ruffwear that easily slips over your dog’s head. Just slip it on, buckle up and you’re ready to go.

This means your dog no longer has to balance on two legs when you put it on!

Other Great Flagline Harness Features:

  • Compact, light profile. It’s cool to wear on hot days, and is friendly to petite and small breed Tripawds.
  • Three leash attachment points. A front-chest loop attachment is great for Tripawds who pull!
  • Debris-resistant liner.

Plus, the same great harness support from Ruffwear!

The Flagline harness offers the same great support for three-legged dogs as the Ruffwear Web Master Plus. It also offers chest and belly protection, without need for the additional Brush Guard attachment.

The bottom panel disperses the weight of dogs in the harness, for additional comfort when lifted. The bottom also adds stability to the harness, further minimizing shifting.

A note about front-leg amputees: The Flagline is truly the best harness for front-leg Tripawds yet. But keep in mind that without that fourth leg, all harnesses may shift a bit during the day. When sized and properly adjusted, however, all harnesses we carry have minimal shifting.

NOTE: Base price includes free shipping via USPS Priority Mail. Ruffwear items do not ship same day. Select desired shipping option to rush delivery. ONLY AVAILABLE IN THE THE UNITED STATES. Find international dealers here.



Harness Sizing

Take your dog’s girth measurement while standing up for the perfect fit. See this video for measuring help.

  • XXS: 13-17 in (33-43 cm)
  • XS: 17-22 in (43-56 cm)
  • SM: 22-27 in (56-69 cm)
  • MED: 27-32 in (69-81 cm)
  • LG/XL: 32-42 in (81-107 cm)

Measure Dog Girth for Best Harness Size

NOTE: In between sizes? Choose the larger size. Ruffwear suggests getting the larger size Flagline harness for dogs who measure in between sizes.

NOTE: We recommend not using any three legged dog harness until the surgery has completely healed and stitches or staples are removed. We have heard of no specific cases where any harness has hampered healing, but we believe direct pressure from the straps may irritate the wound. Please consult your veterinarian with any concerns.

We suggest using a soft towel slung under the belly if additional support is required in the meantime. A reusable canvas shopping bag slit down the sides also makes a handy temporary sling / harness for three legged dog. Find instructions for DIY Tripawd sling here.

    I adopted Biscuit from the pound when he was just 6 months old. He was diagnosed with a rare form of synovial cell cancer in his elbow joint just after he turned 8 years old. It has been a tough road, but he is going stronger every day. Biscuit has always been an athlete and removing his front leg has not slowed him down. My boy has been a front leg amputee dog for 3 months now and I have been through 2 harnesses and one collar, none of which worked for him; they either slipped off or he was able to hook it with his mouth and chew through it. When I got the Flagline harness by Ruffwear it fit exceptionally well. Biscuit was not able to get ahold of it to chew through it and it also doesn’t slip off during our walks. Another thing Biscuit and I like about the Flagline harness is I don’t have to lift him up on two legs to put his arm through. With his other harnesses it bothered him that I had to lift him and thread his arm through one side. With the Flagline harness I just slip it over his head and snap the straps around his body securely, it’s super easy to put on and Biscuit’s walking with his head held high. Another great feature about the Flagline harness is it stays put and doesn’t shift to one side, I also like the added security of the handle just in case he needs assistance. I definitely recommend this harness to any front leg amputee dog.

    Five stars before I’ve even ordered it! Haha!! Though I haven’t even bought it yet, I’m VERY happy to see Ruffwear finally added a connector clip to BOTH sides of the middle strap, as opposed to the pain-in-the-butt slide padded straps featured on the Web Master! I’ve asked for this upgrade more than once! My dog is big so lifting him up, to get his leg through is not so fun and taking that Velcro belly strap off and on every time, is way too much work, plus that belly strap loses it’s shape over time, rolls around and causes chaffing.

    The other advantage the new design appears to have, is much better chest coverage – cause let’s face it – for the moment this is also functioning as a travel safety harness. Can’t wait to get it… been dealing with “not good enough” for almost nine years.

    We were encouraged to get this harness for our newly amputated Golden Retriever before her surgery, to help the Medical staff gently get her to stand post operatively. It has been a god send for us at home for Jenny!

    I am excited that my harness arrived today. I’m not sure how it goes on though. I can’t find any directions. I want to be sure it is on correctly. I put it on her but I’m not sure if I did it right. Is there a link? The only thing it says is begin here. 1. Remove from package. 2. Put on dog. 3. Go outside. I got it out of the package. And I can get her outside. But putting it on I’m not sure if I did it right. Thanks for any guidance.

      🙂 Ruffwear apparently assumes it is obvious with their directions. You’ve likely done it correctly: Slip harness over the head, connect the buckles, and go! And yes, we have this video showing how to put on the Flagline harness. Contact us directly if you need additional assistance.

    4.5 Stars. This is a very nice, sturdy harness for my rear legged amputee. I wanted one w/enough back length for the second set of straps and especially the handle to help steady and support Zora’s rear end, as needed. Zora is a 1 year old smaller “Fox Red” Labrador who is a very strong puller (she stays she’s sniffing) and quite the zig-zagger on walks. After receiving this yesterday, I purchased the Core Cooler pad that goes with it. The reason for the. -.5 star is that took me 45 minutes to get the straps adjusted. As someone mentioned, there are no real instructions, and it’s just very hard to figure out the strapping adjustments for some reason. I’ve had 3 tripods since 2012 so not a complete neophyte on equipment and actually highly recommend the Custom Support Pet Suit for larger dogs – (though I had to add a lot of soft padding spots for the sharper edges on that harness for a barely furred, thin-skinned greyhound). The FLAGLINE harness just happens to be the perfect shape, coverage and weight for my current little 44 lb. girl and we did a neighborhood walk last night to check it out. I am quite impressed with the fit for this particular tripod and will definitely get the same model for this dog if it ever wears out. Thank You VERY MUCH to the Tripawd group for reviews of harnesses and other equipment, I did a lot of research including all the Tripawds reviews and did purchase from this site.

    Correction to my Review of 6/13/2020. The Core Cooler add-on pad is NOT compatible with the Flagline harness. I spoke with Ruffwear Support, and the correct cooling vest that IS compatible with the Flagline harness is the “Jet Stream Cooling Vest”. Exchange was easy and Zora thinks she is quite the Cool Tripod in the ‘hood and stays very cool in the humid/hot weather. Easy to put on and light weight. Does not constrict front leg movement of an active little tripod. Very good fit for this size dog (approx. 45#) and easily fits underneath the Flagline harness . (*My greyhounds use the larger Swamp Cooler cooling vest*.)

      Thanks for the update! That is why we do not offer the Brush Guard with the Flagline, as we do with the “Web Master Plus“.
