Make your dog Safe in your car.
The only easy dog harnesses successfully crash tested to the same standard as a child seat.
1,500 LBF
In a car crash at just 30 mph, an unrestrained 50-pound dog can be thrown with 1,500 pounds of force—enough to cause serious injury to both your dog and everyone else in the vehicle.
Revolutionary Safety: The Two-Tether Advantage
Our two-tether system redefines safety with balanced force distribution. By working together, the tethers evenly spread the impact, reducing strain on your dog’s body and lowering the risk of injury. It’s a smarter, safer design that keeps your dog secure and protected in every moment that matters.
Revolutionary Safety: Total Control with Our Two-Tether System
We’re the only harness system that solves the problem of losing control when transitioning in and out of the car.
Our two-tether design allows you to securely attach your leash before unbuckling your dog, ensuring complete control and safety every step of the way.
Protect your dog like they're family (because they are).
Car accidents are terrible.
All passengers are safer when they're all buckled in. No more loose dogs inside or outside the car
Feel confident taking your dog to more places with just one click.

Hi Dog Lover!
