This is a sincere issue. Most dogs are not fit or trained to ride unsecured in a vehicle. The one exception I have found for this are cattle dogs in the American west who are basically raised and live on the back of a truck. These trucks often don't every leave the dirt road. Dogs which are not secured will be injured, injure a passenger or both during a collision. Ever see a dead dog on a freeway? Most of them have jumped out of a truck or car window.
