I have a two year old adult dog that tends to get motion sick when traveling via car. Short trips to the park are OK, but trips longer than 20 minutes are problematic.  
Normally, we don't feed him at the morning of the trip. We've also tried drugging him, but he still manages to get motion sick or prolongs the actual vomiting events. Changing his location in the car didn't change anything as well.

Does anyone have insight into making life easier for him, and myself? I hate to see him like that.
