Pills are allright & work most of the time but I personally think why medicate a dog if not really needed. You may be able to train her not to get car sick. Most of the time it is due to nerves. Gradually get her used to the car. Start off by just sitting in the car w/ her giving her treats whenever she acts calm. Do this often but keep it short. If possible do each step a few times a day for a few minutes each time for a few days in a row. Then after she succeeds w/ that step then just start the car but do not move. Again praise when she is calm. Then back to the end of the driveway. Then down the street, then around the block etc.... Also by bringing her to fun places will help, a short drive to the park for a nice romp! This ussually takes up to a month or 2. If she starts to get sick in the middle of the process then back up a step and start again from there. Be persisitant & patient. If it fails after a few months then consider meds! Good luck!
