FullStride™ System

More Room to Move.
More Ways to Find Your Stride.

The FullStride™ Flex-Mount Dog Leash was designed for movement with more freedom, more versatility, and more room to find your pace together.

FullStride™ was designed to give active dogs more freedom to move naturally while still maintaining the lateral control and connected feel that make the u.Do:™ experience unique.

Unlike systems that keep dogs locked tightly at your side, the FullStride™ flex-mount design allows your dog to move slightly ahead or behind your stride while remaining connected through the ergonomic L-bar handle. The result is smoother movement, better rhythm, and more natural pacing together.

Whether you’re walking, jogging, or running, FullStride™ helps create comfortable stride separation without sacrificing awareness, communication, or control.

The ergonomic L-bar handle also encourages improved posture and upper-body engagement while helping reduce pulling, twisting, and tangled leash movement.

Especially helpful for:

  • Dogs with longer natural strides
  • Faster-paced walkers or runners
  • Dogs learning movement consistency
  • Handlers who prefer additional spacing
  • Active outdoor workouts and fitness routines
Flex-Mount Design Allows more natural forward and trailing movement
L-Bar Handle Supports posture, awareness, and upper-body engagement
Connected Movement Maintains communication and lateral control together
Recommended Use: FullStride™ systems are generally recommended for dogs approximately 20–100 lbs, though temperament, training level, and movement style should always be considered when selecting your system. Use our Sizing Guide to find the right fit for you and your dog.
Every workout is better with your best friend.
