As people around the world start to travel again, dog owners should be aware that many airlines have changed their rules on pet travel during the past year. So what do you need to know before flying with your dog, and what are the various airlines’ requirements? We’ve got you covered.

Note: These guidelines are for dogs considered pets. Most airlines allow fully-trained service dogs to ride in the cabin without a carrier. Airlines are no longer required to accommodate emotional support animals (ESAs) and they must travel as pets.

Should You Fly With Your Dog?

The first question is, should you fly with your pet at all?

Though air travel is sometimes unavoidable, it can take a toll on dogs’ health and emotional wellbeing. Dr. Jerry Klein, Chief Veterinary Officer for the American Kennel Club, notes: “Traveling by air can be stressful to people and to dogs,” adding that the strange sounds, sights, and smells of airports and new destinations can be challenging for pets. Meanwhile, changes in diet and water on arrival can affect dogs’ gastrointestinal health, and the upheaval of traveling and time-zone changes could lead to dehydration or interruptions to strict medication schedules, such as insulin for diabetic dogs—leading to potentially serious consequences.

As those warnings suggest, air travel is most likely to be challenging for older dogs or those with an underlying medical condition, impaired immune system, or heart condition. If your dogs fits into one of these categories, consider flying with them only when absolutely necessary, and always make sure to prepare well to make sure their needs are met.
