Built for Security
Most harnesses can't handle the rigor of large breeds. The Eclipse was designed from the start to handle the specific forces a giant breed generates both on the walk and if you need to secure them in your car.
Control without compromise
The Eclipse gives you full control on the walk — multiple attachment points, hardware rated from 1,500–2,200 lbs, adjustable fit, and MIL-W-17337 nylon webbing that holds its shape under sustained load. Built for dogs that lean, lunge, and pull with their full body weight.
In the car — hardware rated for the forces that matter
The buckles and load rings are rated 1,500–2,200 lbs of force. Clip into a standard seat-belt adapter at the back ring and the harness holds where a standard plastic buckle can crack. The Eclipse is not crash-tested to an automotive safety standard — it's rated hardware for secure vehicle restraint, not a certified crash-test device.
What Eclipse is made of
Giant breeds that need equipment, not accessories.
Newfoundlands, Cane Corsos, Great Danes, Saint Bernards, Mastiffs — dogs whose size and strength demand hardware rated to match. Dogs that ride in the car and need a harness that actually holds in an emergency. Dogs that have destroyed everything else.
The DUO Guarantee
Lifetime guarantee on materials and workmanship. If the Eclipse fails for any reason — we repair or replace it. No time limit, no fine print.
"I adopted a street dog from India — reactive, fearful, slipped every harness I tried. I couldn't find anything that worked. So I engineered something that did. The Eclipse is what happens when you apply that same thinking to construction instead of mechanism."
Raj — Founder, DUO Technical Gear
The quality of the product is way above what I expected!
Amazing harness for giant breed dogs!
We have a very large very strong 2.5 year old male Anatolian Shepherd. He weighs in at 150+ lbs. with a 26" neck and a 40" chest and is pure muscle. He lives in the house most of the time, but also spends time with us at our barn which is fenced in. We built a very strong industrial like trolley system to get him from the house to the barn and vice versa. There are tie outs on both ends to get him to and from safely in and out of the door or the gate to the trolley line. Our problem is he is EXTREMELY reactive and will "take off" at the sight of a person, squirrel, bird, rabbit or the neighbors unleashed dogs. If it is in his sight, it belongs to him. The power behind him is incredible. It isn't a training issue, it is an instinctual issue. We bought what we thought was a "heavy duty", "strong enough for him" harness for the system. He took off after a squirrel we didn't see, hit the end of the line (it is cushioned and he wears a heavy duty bungee) and the harness he was wearing blew apart. Now he's loose! He didn't continue after the squirrel and we are lucky he didn't realize he was loose or other dogs ran out. I was able to calmly grab his collar and get him inside. Very shaken to say the least, we immediately jumped online to search for "something" that will hold him if and when that happens again. My husband landed on the Duo-Gear website and actually was able to chat with a live person on the weekend! That person happened to be Raj, the owner of Duo-Gear. I jumped in and explained our situation and what we needed. He offered to customize the Duo "Eclipse" harness for our Auggie. He added extremely strong Cobra clips and heavy duty rings as well as extra box stitching. He described it as "bullet proof". It is important that the rings are structural, not just sewed in to handle this kind of power. Raj said that he would get us pricing within a few days, which he did. He also said it would be ready in about 2 weeks, which it was. We kept in contact from start to finish and then again to share a success story. Auggie bolted on Sunday morning after another squirrel. This time in his new custom made Duo Eclipse harness. Every piece of equipment did it's job as it was supposed to. We inspected the harness very closely and don't see anything out of place. We are so grateful to know that he is safely contained now. Thank you to Raj and everyone involved on the Duo side for your understanding, attention to detail and above and beyond excellent customer service. (sorry that was so long!)
I have been through 2 harnesses already. This harness isthe best. Sturdy easy to put on and as a bonus I am in love with the hardware. So upscale my dog is the most stylish
If you're looking for gear that is built to last, Duo Gear is it. Our Cane Corso is a beast, and his harness gives him the ability to move freely while giving us the reassurance that he is safe. Support your Veterans...they know how important quality gear is!
Quality, American made, great customer service.
I am so excited to use these harness on my every day walks and adventures with my dog Neena! ☺️ I am so thankful I've come across a quality company which highest grade of materials which craft these harnesses. Especially for a strong puller like mine this will put everything at ease! Also- on a side note - Raj the owner has been amazing, professional and so quick to respond to any questions or helps with anything you inquire on. Amazing customer service and company. I have confidence and trust in Duo Gear. Cannot wait for my dog to try these on ☺️
Thank you Raj to you and your team!
The only brand that fits my great Dane. This is my second one with them. Very high quality. Last a long time despite. Worth the cost.
I had a really hard time finding a harness to fit my Great Dane. I found this harness and it fits him perfect. The quality is great and I love that it is made in USA. I see it in the pictures on the website now, but didn’t initially notice the strip for a hook and loop name tag behind the ring. That’s a great feature. Would definitely recommend this harness.
I received my new Duo Eclipse last week. My dog King and I walk 2 miles every day and he just loves it. He adjusted to this new design the first day and now its like he has had it for years. Quality and durability seems top notch.
