Ginger tea helps with motion sickness. My bird used to be sick in the car, and upon advice of a pet owner, I offered him ginger tea (ginger slices steeped in hot water, then cooled) about 30 mins before we hit the road. It worked, no more chunky bunkies. I also heard of feeding gingersnaps as well.
Good luck, and congrats on your puppy.
