Make your dog safe in your car.
The only two click dog harness successfully crash tested to the same standard as a child seat.
When compared to others.
Optimus Gears Defender Harness is the most durably constructed crash-tested dog harnesses we reviewed. It’s designed to withstand impact forces with stress-tested custom metal buckles and hardware and high-strength webbing. And the padded chest and back panels made the harness comfortable. And with chest and back leash attachment points, it’s also convenient for short walks.

Hi Dog Lover!
We understand—keeping your dog safe in the car shouldn’t be so complicated. Yet for years, pet owners have faced the same struggles: harnesses that break under pressure due to poor materials or designs, and systems so complicated that threading seatbelts feels like solving a puzzle.
At Crash Safe Dog, we believe your dog’s safety is non-negotiable. That’s why we make all our harnesses here in Canada, using the highest-quality materials and a design that’s as simple as it is effective. With just two buckles to clip in, your dog is secure, and your mind is at ease.
