Safety & Fit Guidance

Move Confidently.
Choose Thoughtfully.

u.Do:™ systems are designed to support active movement with your dog, but every dog and handler pairing is different. Proper fit, training, awareness, and responsible use are essential.

Safety Recommendations

  • Always inspect your equipment before use.
  • Gradually introduce your dog to new movement routines.
  • Maintain awareness of terrain, traffic, distractions, and surrounding conditions.
  • Never leave dogs unattended while attached to any system.
  • Consult your veterinarian before beginning strenuous activity with your dog.

Weight Recommendations

PowerStride™ and FullStride™ systems are recommended for dogs approximately 20–100 lbs.

SureStride™ and FreeStride™ systems do not have specific dog weight limitations.

These recommendations are general guidance only. Individual dog behavior, training level, strength, and movement patterns should always be considered when selecting a system.

u.Do:™ is not responsible for injuries or damages resulting from improper use, misuse, lack of training, or failure to follow safety recommendations.

Dog Size Matters

Sized Right for Your Adventures

Every u.Do:™ system is designed for a different style of movement, control, and spacing — and your dog’s size plays an important role in choosing the right fit.

In this video, Jeff explains why dog size matters, how each leash system is engineered differently, and what to consider before choosing your stride system.

Proper Fit Matters

Secure. Comfortable. Supported.

A properly fitted collar or harness helps your dog move confidently while improving comfort, safety, and connection during every walk, run, or adventure together.

In this video, Jeff explains how to adjust your gear for the right fit — including collar sizing based on neck circumference and harness adjustments that accommodate both the neck and chest for balanced support.

Fit Tips

Collars: Should feel secure without being restrictive. Proper neck sizing helps maintain comfort while keeping your dog safely connected.

Harnesses: Require a more customized fit through both the neck and chest areas to provide stability, comfort, and freedom of movement.

Connect With Confidence

Your PowerStride™ system is designed for fast, secure connection and smooth disengagement when your adventure begins — or when it’s time to head home.

In this video, Jeff demonstrates how to properly attach and release the PowerStride™ leash system so you can move confidently knowing your setup is secure and ready for the road ahead.

Quick Tips

Listen and check: Make sure the connection point is fully engaged before beginning movement.
