an accident.
some do! if this happens, call your veterinarian for car sick medication. it also helps to start with short trips and then gradually increase them.
adult dogs should avoid flying in the cargo area of a plane, unless it is a special transport company for animals. only bring your dog on a flight if he can safely travel with you in the cabin, and he is trained to ride comfortably in a crate.
if your adult dog is an experienced traveler, he should do very well in a hotel. make sure he is well behaved. (if unsure, use a crate!) also make sure he gets outside often enough to relieve himself.
