If your dog loves to ride in the car then you need this pet safety harness for them! It features a zip line to install in the car and a harness to go on your dog. By attaching them to the line your dog will be safe from hard braking and unable to jump into the front seat during driving. When you open the car door they won't be able to jump out until you unclip them. Can also be used on boats as seen in the picture.
