We try to take Nina in the car several times a week especially since we also plan to take her on a motor home vacation next summer. Yesterday afternoon we went to soccer, back and forth altogether about 50 minutes. Most of it on the freeway. In between I walked her around the soccer field for about 2 hours, and the kids also took her running. After we came home she had a her kibbles. Three and half hours later we took her in the car to pick up a friend, about 15 minutes each way. Just before we came home I heard my DD scream, "Ooooooohhhh!" Nina had vomitted up her dinner all over DD.
She never before got car sick but I think it was from driving. She generally shivers part of the time when she is in the car.
