Being held in place when one is accustomed to having freedom takes some getting used to, whether it’s humans or dogs. Having someone sit with the canine passenger can help immensely, by keeping their mind occupied with pets and other forms of positive reinforcement while they ride. It can also help to crack the car window, so they can smell the breeze. The key is getting them used to sitting in place and getting them to realize they can enjoy the ride from a single position.
