baby and the car (new mom to dog)

Baby hate the car so much. Every time I open the door she run to the bed and hide. Last month we need to go to the vet in Samut Prakan and she cry the whole way, the neighbor call the police lol no joke. What I try now: I put her blanket on the back seat and let she sit there with the engine off. Only 5 minute, then I give her treat. After 2 week I start to turn the engine on, only drive to the end of the soi and back. Also dont feed her before car, she vomit very bad. And crate on the back seat, not on the floor, she feel safer when she can see the window. Its take some time, but she is better now and jump in by herself sometimes.
