Unbelievably hard for one year old dog to have a car ride first time

One year old Chance never be in a car ride before. We tried to help her by using her favourite treats and also using a ramp. However, in any case she does not have courage to jump in the “monster box”. It is such a frustration that you can not take her to anywhere that is not walkable distance. We gave up the try for her to climb to the trunk, and just try the second row seats. After a few times try, she made it, even she shakes when car moves. This is a big step for us! Thanks God!
