This is a design by a 15-year-old high school student. A few years ago, his dog was in a car without any safety measures and suffered a serious leg fracture due to the vehicle's sudden braking.In many countries, there are already regulations that require vehicle occupants to wear seat belts, but the issue of pet safety in cars is often overlooked, and it's even difficult to find suitable products on the market.This invention primarily provides a safety vest for dogs to wear while traveling in a vehicle. Unlike other products, the center of gravity of this vest is designed to be on the dog's abdomen, with a strengthened structure on the back. This design allows the impact from sudden braking or a collision to be distributed to the dog's back and across a larger surface area, preventing the force from concentrating on the abdomen. It also helps to prevent injuries to the legs, thus reducing the risk of injury to both the dog and the human passengers.
