You should probably talk to your vet about that, but my yorkie Dexter also gets carsick and my vet told me to use Benadryl. You could talk to the vet about using that and they can tell you how much to use, etc. I think they also just released a new medicine for car sickness. So, yeah, I'd talk to your vet about it....
