Flying with your dog can feel overwhelming, especially if it’s your first time navigating airline rules, health documentation, and packing requirements. Once your flight is booked, creating a dog travel checklist for air travel can help ensure you pack everything your pet needs while meeting airline requirements.

Packing needs may vary depending on how your dog will travel. Some pets fly in-cabin in an airline-approved carrier under the seat, while others travel in the cargo hold in a larger crate, each with its own packing requirements.

This guide covers everything you need before your flight, including a complete dog packing checklist for in-cabin and cargo travel and common airline rules.

Dog Packing List

Whether your dog is flying in the cargo hold or in-cabin, there are a few dog-friendly travel essentials to bring along to ensure that your pet is ready for travel:

Health and travel documents: Most airlines require documentation showing that your dog is healthy and up-to-date on vaccinations. Common documents include a veterinary health certificate and proof of rabies vaccination records. Some destinations may require the health certificate to be endorsed by a government authority and additional permits.
Airline-approved travel crate or carrier: Your dog needs a crate or carrier that meets airline safety and size standards. Small dogs flying in-cabin typically use a soft-sided carrier that fits under the seat. Larger dogs traveling in cargo must use a rigid kennel sized appropriately for the dog. Some breeds may require a reinforced CR-82 crate.
Identification tags and microchip: Your dog’s collar should include an updated ID tag with your contact information, particularly your phone number. Many international destinations also require an ISO-compatible microchip to verify your dog’s identity.
Leash or harness: Dogs must remain leashed when outside their crate or carrier in airports. A secure harness can make it easier to manage your dog during check-in, security screening, and bathroom breaks.
Comfort item: A small item that smells like home can help reduce travel anxiety, especially when your dog is adjusting to a new environment. Many pet owners bring a soft T-shirt or blanket with their scent to place inside the carrier or crate.
Calming supplements or pheromone sprays: Some owners choose calming treats or pheromone products designed to help pets relax during stressful situations. If bringing sprays, be mindful of airport liquid restrictions and airline guidelines.
Waste bags: Bring extra doggie poop bags so you’re prepared for bathroom breaks at the airport and immediately after landing.
Dog food: Pack enough pet food for the journey and the first few days after arrival. This avoids sudden diet changes and gives you time to find your dog’s regular food at your destination.
Basic first-aid supplies: A small pet first-aid kit with items like gauze, antiseptic wipes, and tweezers can be helpful when traveling away from home.

Cargo-Specific Items

For dogs flying in cargo, start with the airline. They’ll let you know of any flight requirements for dogs specific to that airline and your destination. From there, here’s a pet travel checklist applicable to most dogs in cargo:

International Air Transport Association (IATA)-approved crate: The size of your crate depends on the size of your dog. Spend time before your flight crate training your dog to help them feel calmer and more confident inside.
Photo of your dog: Tape a clear, recent photo of your dog to the outside of their crate for identification purposes.
Absorbent pad and/or blanket: A puppy pad will help keep your dog dry in case of accidents. A thin blanket can make them more comfortable.
Food and water bowls: These should be attached to the inside of the crate door and accessible from the outside. Loose water bottles or bowls are not allowed.
Bag of food: Some airlines request that you attach a small bag of food to your dog’s crate on especially long journeys. Check with the airline about your travel itinerary. Make sure to include feeding instructions as well.
Special instructions: Attach any special instructions for pets on long-haul flights to the crate.

Things Not to Bring

Airline restrictions for pets traveling in cargo are designed to reduce risks during transport. The following items should not be placed inside your dog’s crate:

Loose toys or treats: Your dog’s favorite toys can become choking hazards during the flight. While a soft T-shirt or cloth with your scent is usually allowed, most airlines discourage placing multiple objects inside the crate.
Leashes or harnesses: You’ll need these for your trip to the airport, but these should not remain on your dog inside the crate. They can become tangled during transport.
Large blankets or dog beds: Bulky bedding can restrict airflow inside the crate and increase the risk of overheating. A thin blanket or crate pad is typically fine.
Sedatives or tranquilizers: These medications can affect breathing and balance during flight, and your pet could be denied boarding if they’re visibly sedated. If your pet is on existing medications, talk to your vet about timing those meds if needed before air travel.

What to Bring In-Cabin

There are generally fewer restrictions on toys and treats for small dogs flying in-cabin, which can make it a convenient option for short flights.

For longer journeys, cargo travel can be more efficient and may involve fewer layovers. In some cases, your pet may need to travel in cargo depending on airline rules or flight logistics. A professional pet shipper can help you navigate a more complex itinerary.

If you choose to fly with your dog in-cabin, here are the pet travel essentials to help keep them comfortable and compliant with most airline regulations:

Airline-approved carrier: Size constraints may vary by airline depending on the airplane. Choose a soft-sided pet carrier that fits under the seat in front of you.
Absorbent pad or blanket: Line the carrier with an absorbent pad or their favorite blanket for comfort and to help manage any accidents. Avoid bulky blankets that restrict space in the carrier.
Paper towels: Bring a few loose towels in your travel bag for clean-up in case of emergencies.
Collapsible bowls: Bring portable travel bowls that you can fill with water and/or food. Keep collapsible water dishes empty outside of watering times to avoid spills mid-flight.
Empty water bottle: While you can’t bring full water bottles through security, most airports have water filling stations where you can fill up your bottles.
Dog treats: Pack a few treats to keep your dog calm or distracted during the flight. Just don’t overfeed them to avoid nausea. Avoid large food containers that may spill or create odors.
Soft toy: A quiet chew toy or a small plush can help keep your dog occupied and reduce anxiety. Avoid bringing noisy or squeaky toys that may disturb others, and leave potential choking hazards at home.

Airline Policies and Regulations

Airlines have specific rules for traveling with pets, so it’s important to review your carrier’s policies before booking. Policies cover which pets can travel and where (in-cabin or cargo), what documentation is required, and what items are allowed in the carrier or crate. Some breeds, such as strong-jawed or snub-nosed dogs, may be restricted or banned altogether.

When packing for your pet, most pet-friendly airlines allow small amounts of food and water, along with comfort items like a blanket, T-shirt, or quiet toy. Make sure all required health documents, including vaccination records and certificates, are ready for inspection.

Airlines also restrict items that could pose a safety risk, especially in cargo. Avoid loose toys or treats, leashes or harnesses inside the crate, and large blankets or beds that could block airflow.

Avoid sedatives, and any regular medications should be timed according to your vet’s instructions.

Additional Travel Considerations

When traveling internationally with your dog, requirements and travel tips vary by country. Some destinations may require extra health certificates, vaccination records, or government-approved permits, as well as specific treatments, like parasite or heartworm prevention, before entry.

Many countries require an ISO-compliant microchip for identification, and rabies or other vaccines must be up to date and administered within the required timeframe. Health certificates are generally only valid for a limited period before travel, so plan veterinary visits accordingly. Missing or late documents can result in delays, denied boarding, or quarantine upon arrival.

Even if you’re flying domestically, carefully reviewing airline requirements is still important. Planning ahead ensures a smoother, less stressful travel experience for both you and your dog.

FAQ

Start by acclimating your dog to car travel well in advance of your long road trip. Take short practice car rides to get them comfortable with movement and being restrained in a crate or dog seat belt harness.

Bring familiar items like a favorite blanket or toy, schedule regular rest stops and bathroom breaks, and pack water and food for the getaway. For anxious dogs or dogs that get carsick, talk to your vet about safe calming strategies.

How you pack your dog’s food before their flight depends on how they’re getting to their destination.

For in-cabin flights, bring enough food for the journey and pack it in your carry-on with a collapsible bowl. Pack food in sealable bags to avoid spills or odors. For dogs on wet food or specialized diets, ensure the food meets TSA guidelines on liquids and banned items.

For dogs traveling in the cargo hold, the airline may ask that you attach a small, secure bag of food to the outside of the crate in case of a long flight or delays. Food bowls should be attached to the inside of their crate and accessible from the outside. Include feeding instructions.

Dogs are not allowed to occupy a passenger seat. This includes service animals. All in-cabin pets must travel in an airline-approved carrier under the seat in front of you.

A few airlines allow passengers to purchase a second seat for an additional in-cabin pet, but this is rare and usually subject to weight limits, carrier requirements, and airline approval. Always check your airline’s pet policy to understand restrictions, fees, and allowable carrier dimensions before booking.
