RE: Motion Sickness
Hogan...you've recieved good advice. Let me add one more thing you may or may not be aware of. Dogs, (especially puppies) will vomit regularly if they have been fed within 1 to 3 hours prior to going for a ride. For instance, when I'm going hunting...I feed them well the night before and they get no food until after we get home from the days hunt. Ocasionally, we give snacks while hunting, but they usually won't eat them until they're done hunting.
If we have a trip planned to the vet, they get no food until after they get home. Nerves are another cause for them to vomit.
Good luck,
Rick
