The DogGoBelt is designed to ensure the safety of our canine companions during car journeys, particularly in cases of sudden braking or accidents. DogGoBelt is a fully functional seat belt designed for dogs. With a strength rating of 14 kN, DogGoBelt shares the same features as seat belts used by humans. With DogGoBelt, your dog will be able to move around on the back seat of your vehicle. In the event of an accident or sudden braking, the seat belt will automatically lock. This locking mechanism will not only ensure the safety of your dog but also prevent other passengers in the vehicle from being harmed by your dog's movement. DogGoBelt attaches directly to the seat belt buckles in the rear seats of the vehicle. However, the buckles used for the center seat are different from the others. They are designed with a coded mechanism to prevent misuse of the right and left seat belts. Therefore, do not attach DogGoBelt to the center buckle.  Please attaching DogGoBelt to the seat belt buckle in your vehicle in a way that does not close the buckle's release button
