Transporting a pet by air involves a lot of prior arrangements, expense, permits and paperwork. It is extremely stressful and dangerous for the pet. Reconsider your decision to take your pet.If you travel by air, you must arrange in advance to have your pet travel on the same flights. You will have to pay for transporting your pet as cargo unless it is so small that you are allowed to carry it in the aircraft cabin. Your pet will travel AT ALL TIMES in a carrier kennel crate like this, of a size appropriate for your pet (large enough to stand and turn around): The carrier kennel crate must be acceptable to the airline -- each airline has its own standards. Pets in carriers travel as baggage in the hold of the aircraft, and are exposed to high heat on the parking ramp and in baggage handling areas of the airport. Most airlines refuse liability for heat threats to your pet, and many restrict carriage of pets to cool seasons. Plan to travel with (or put on/in the carrier crate) your dog's leash, a bowl for water/food, plastic bags (and probably absorbent diapers for wet cleanups) to dispose of wastes, and perhaps some canned food. Any unpackaged food or treat is forbidden. The pet should wear a collar with ID tag and contact telephone numbers.The US Centers for Disease and Prevention (CDC) regulates importation of pets into the USA.
