Never Compromise on Safety
Your dog deserves better...

Any harness or restraint placed high on your dogs shoulders and neck has a risk of causing severe neck and spinal injuries. Most harnesses are designed to secure your dog to the harness by using a tether or seat belt type strap. These straps are attached directly behind the shoulders near the neck... this is an extremely dangerous design. Even a simple quick or emergency stop with a tether or leash will cause a “Shock Effect” abruptly jerking back on the tether and harness together. This intense jerking force can result in broken bones, neck trauma, thyroid injury, spinal injuries, paralysis or worse. Other passengers inside a vehicle are also at risk of being tangled in a tether, becoming injured as well.

Big Dog Seat Belt Reviews

Gail W.

It was put to the test this weekend! Heavy traffic on the highway, a very short stop of the truck in front of us and She was saved from going from the back seat into the front seat. Very pleased with the security of the unit. Kota is a big dog and it fits her perfectly, did the job it was designed to do, and that’s save her from injury.

The seat belt is beautifully made, and we feel very safe having our Vizsla in it. The owner of the company worked diligently to have everything correct (measurements, etc.) to fit our dog. I highly recommend this company!! Thank you!
