Ginger biscuits are good or there is something from PAH that has ginger in it a natural remedy it worked for one of my dogs.The breeder recommended ginger biscuits.

i have the exact same problem with Bonnie, and i know how you can lose the will to live when your constantly cleaning the car.

i've tried a covered/uncovered cage, Johnsons travel pills (sicked these up), short trips with play, sitting in the car and playing(whilst engine off/on),ginger biscuits,starving,
and nothing has worked.

i've bought some scullcap and valarian and have yet to try them.

i know her sickness comes from travelling over from Ireland in horrendous conditions and its going to be a hard nut to crack but i will try anything to break the bad association with the car.
