First, it is
important that any dog suspected of having
motion sickness not be fed for at least a couple of hours before a car trip, as vomiting food becomes more likely if food is in the stomach.7 Once in the car, simply allowing fresh air in or allowing the dog to see out may help alleviate
motion sickness in some dogs.7, 8 This is
particularly true for puppies, who tend to be either fearful or
motion sick more often than older dogs.8
