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!
