Frequently Asked Questions

Start with how you and your dog move together. PowerStride™ is built for running and training-focused movement. FullStride™ gives your dog more forward and trailing distance while still keeping you connected. SureStride™ offers steady control with hands-free flexibility, and FreeStride™ Gear is a more affordable, versatile option for everyday adventures.

PowerStride™ keeps your dog closer and more aligned with your stride, which is helpful for running, training, and controlled movement. FullStride™ allows more natural forward and trailing movement, making it a better fit for dogs who need a little more room while still staying connected to you.

A top-mount leash connects from above your dog, typically to a top-mount harness. A side-mount leash connects from the side and is designed to help keep your dog positioned beside you. The right choice depends on your dog’s training, movement style, and how much alignment you want during walks or runs.

Yes, but we recommend building within the same system when possible. PowerStride™ components are designed to work together, while FullStride™, SureStride™, and FreeStride™ products each have their own intended use. Matching the right leash with the right connection point gives you the safest, smoothest experience.

Measure your dog where the collar or harness naturally sits, then compare that measurement to the sizing guide on the product page. If your dog is between sizes, choose the larger size for comfort and adjustability.

Yes. Most u.Do: collars, harnesses, belts, and leash systems include adjustable features so you can create a more secure, comfortable fit for both you and your dog.

No. PowerStride™ is especially designed for running and training-focused movement, but many u.Do: products can also be used for walking, hiking, and everyday adventures. Choose the system that best matches your pace, control needs, and your dog’s behavior.

Some products are better suited for multi-dog use than others. For example, certain FreeStride™ hands-free leash options may allow an optional second leash. Always check the product description and use only as directed.

u.Do: systems are designed to support safer, more confident movement by helping create a more predictable connection between you and your dog. No leash can eliminate every tangle or trip risk, so always pay attention to your dog, your surroundings, and the product’s intended use.

Basic leash manners are strongly recommended. A fixed-distance system can support better movement together, but it is not a substitute for training. Start slow, practice in a low-distraction area, and build confidence before running or moving in busy spaces.

u.Do: products should be used by someone able to safely control the dog. Children should only use leash systems with adult supervision and with dogs they can confidently manage.

Only products specifically described as car safety or travel products should be used in a vehicle. Standard leashes, collars, and harnesses are not crash-tested vehicle restraint systems unless clearly stated.
