Two lines. One patented system.
See how it works
The patented cinch mechanism demonstrated — both models.
Why it works when nothing else has.
Most harnesses are passive — they slide around, twist and pull off your pups body. The DUO harness is different. It adapts and responds to your dog's behavior in real time to give you superior control.
Patented Innovation, Design and Durability
Thoughtfuly designed for the needs of athletic, high energy, reactive, or hard to handle pups. Our patented No Pull design is secure, humane and built to last.
Built for Every Breed and Temperament
From small to giant breed — every size, every temperament. Backed by a lifetime guarantee on materials and workmanship
Fantastic Harness for Big Dogs
The Duo Direct No Pull Harness has exceeded our expectations. Our Newfoundland always sled dog pulls for the first half of his walk, even using a prong collar. The first time we put the Duo Direct No Pull harness on him he didn’t pull at all. He was calm and walked right by my side. He loves his new harness and best of all we no longer have to use a prong collar on him.

Control without a struggle
As an owner of a giant breed dog, I have found it very difficult to find a harness to fit my male Great Dane, Max. Weighing in at 170 pounds, I have never found a harness for him that actually fits and performs as promised until now. The Duo Tech harness fits him perfectly and allows me to maintain control of him on a leash without a struggle. I highly recommend this harness for giant breeds, which are often overlooked by many brands. Thank you for your amazing American made products.

Hardy harness!
This harness is the bees’ knees! It’s sturdily built, low-profile, dang good looking, and has had a pretty immediate and positive impact on our newly-adopted GSD. USPS wouldn’t update, so I reached out and got excellent customer service! Where else can you find a US-made, high-quality and well-designed product with a great support crew? Well done, y’all!
