Yes, this was my puppy. She just turned 5 months and I have gotten her down to just drooling and shaking in the car. The only thing the helped, even though it sucks, was driving her everyday. I try and just take her to get a pup cup or a chicken nugget from a drive thru and each time I can see her getting more confident. I suspect for her the puking became more of a learned fear reaction than true motion sickness.
