Stay In Control. Keep Them Safe.

After many different leash length protypes and hours of real-life testing with dogs of all breeds, sizes, and personalities, we found the sweet spot is 3 feet. Here’s why it works so well:

Total Control, Zero Hassle
Three feet of refined design keeps your dog close through mountain trails, everyday hikes, city streets or surprise distractions. It prevents tangles and lets you release safely when the moment’s right.

Quick-Grab Magnetic Handle
Need extra control at a moment's notice? A built-in magnetic grab handle sits right behind the leash so you can pull your dog close in seconds. No fumbling, no fuss.

I love the harness. It’s super easy to put on and it allows me to walk without having to hold the leash and then try and get a leash on my dog.

I have been working as a positive reinforcement dog trainer for a while now and I’m constantly looking for practical, helpful products for both owner and dog and I think your harness is the best product I have ever used.

FAQs

The leash is fully built into the harness, so there’s nothing to carry or clip on. It’s always right there when you need it.

The leash housing on your dog’s back is lightweight, under 4 oz, and contains our custom, proprietary attachment system . Similar in concept to a retractable leash, the unit allows the leash to extend and retract automatically. When you reach for the handle, it glides out to its full 3-foot length, giving your dog room to move safely and under control while keeping them close and manageable.

When released, the leash retracts neatly back into the harness. When fully retracted, the handle rests securely in place and does not touch your dog’s back.

Our S/M fits dogs 15–35 lbs, and the M/L fits dogs 35–80 lbs. FreeRun is designed to fit a wide range of body types thanks to its highly adjustable design. Whether you have a narrow, deep-chested breed like a Greyhound or a broad, wide-chested dog like a Bernese Mountain Dog, the harness can be fine-tuned to achieve a secure, truly custom comfortable fit.

We’re also in the final stages of prototyping an L/XL size designed for dogs 80–130 lbs.

Yes. The leash housing has been both lab tested and proven in real-world use to withstand up to 250 lbs of force, giving you reliable performance when it matters most. It’s built with stainless steel internal components, including a welded steel attachment pin that the leash is triple-stitched to, all housed in high-durability materials designed to perform under pressure, not just ideal conditions.

The leash itself is made from high-tenacity polyester narrow-woven webbing (NWF), the same material used in seat belts. It’s incredibly strong, with minimal stretch, and offers excellent resistance to abrasion and UV exposure for long-term durability.

Yes. FreeRun is fully water safe and built to handle real outdoor conditions, from rainy walks to swim days. Whether your dog takes a swim in a lake or romps through the saltwater waves, the harness is designed to keep up. The materials were intentionally chosen to resist water, corrosion, and wear, including stainless steel internal components and durable, quick-drying webbing. The housing is designed with drainage in mind, so water won’t get trapped inside. Wherever your adventures take you, FreeRun is made to perform right alongside you.

FreeRun’s 3-foot leash length is highly intentional. Safety and control guide every design decision, always coming first. If a longer length could have been added without compromising performance or reliability, it would have been.

After extensive R&D and real-world testing with dogs of all shapes and sizes, the results were clear. Longer leashes, especially 6' and 8', created real safety and usability issues. They dragged on the ground when released, tangled around legs and obstacles, and even at 4', the handle could recoil along the dog’s back and cause discomfort.

At 3 feet, the balance is right. You and your dog can move comfortably through sidewalks, trails, and parks with control close at hand. And when it’s safe, simply let go and allow your dog the freedom to explore, knowing connection is always within reach.

FreeRun is built to last, and it’s backed by a 2-year warranty on the leash housing and all attachment buckles under normal use. These are the core components designed to perform day in and day out, and they’re made to hold up to real-world conditions. Like any gear, there are limits, and the warranty does not cover damage caused by chewing, as even the strongest materials can be compromised by a dog’s teeth.
