UniFly™ Harness

guide dog harness + handle system

The UniFly is more than a guide dog harness - it's the unique line of communication between a human and their guide dog as they navigate every day life. It allows the handler to feel the subtle nuances of the guide dog's movement, enhancing feedback exchange. Both harness and handle feature several points of adjustment and connect at a single, easy-to-use attachment point. The lightweight, padded harness has an internal frame that moves with the dog, free of distractive rubbing or chaffing, and equipping them to lead the way in comfort and confidence.
