Dogs that are traveling with owners have to be obedient and not cause undo noise or a problem in the plane. Usually if a dog is loud or restless, he or she will need to be crated or the owner and dog will need to arrange for another flight. If you have any concerns talk to your vet as he or she may be able to prescribe a mild sedative that will help your dog stay calm during the travel time. If you brought your dog in a carrier it will need to be stored under the seat just like any other piece of baggage. The only dogs that can be on the plane out of a carrier are guide dogs and even they are trained to lie down under the seat ahead of their masters. Most airlines only allow a specific number of dogs in the plane so be sure to notify the airline when you book your ticket that you are bringing a dog on the plane with you. If you did your airline booking online, you will want to call the airline to make sure they are aware that you bringing a dog on board, thus preventing any confusion that may arise during the security check and boarding process.

Larger dogs that are traveling in crates will require special care. Do not feed or give water to the dog for at least six hours prior to the flight, which will help minimize the change of vomiting or messing in the crate. And if you bought stuff like dog clothes cheap and packed them in the crate, make sure they are secure. Provide a soft, easily washable bedding or blanket in the crate along with a toy to keep the dog occupied. Make sure the crate is approved by the airline, phone ahead or check on the airline website for specific types and measurements of dog crates that are approved. You can't just rely on the crate's closure alone, so it will be important to use bungee cords or another type of fastener to secure the door. If it catches on luggage or is bumped during handling it can spring open and your dog can get loose in the airport.
