I don't know if you can still buy static strips that hang off your bumper. I haven't had a dog that needed them for quite some time now but they did work wonders for dogs that had trouble travelling - be it getting sick or not being able to settle. I agree with Danisgoat about desensitizing the dog to the car and would follow her instructions. Sometimes it's the hum of the engine that gets them going. If you can get someone to sit in the back seat with her when you get to moving the vehicle - preferably you sit with her while someone else drives back and forth in the driveway it might give her additional security. Work on getting a block away from home then park the car to take her out for a walk and then back into the car and home again for a game in the yard before going into the house. Try to do it daily so that she learns to equate the car with fun.
Don't give up - it can take some time before a small success occurs to give you hope of a better tomorrow.
