How Do You Fly With a Big Dog: The Ultimate Guide for Traveling with Your Large Canine Companion

Flying with a large dog can seem daunting, but with proper planning and knowledge of airline policies, you can make the journey smooth for both you and your furry friend. As someone who’s traveled extensively with my own large breed dog, I’ve learned the ins and outs of air travel with oversized pups. This guide will walk you through everything you need to know about flying with a big dog in 2025.

Understanding Your Options for Flying with Large Dogs

When it comes to flying with big dogs, you generally have two main options:

1. Flying with your dog in the cabin (preferable but limited)
2. Flying with your dog in cargo (more widely available but potentially stressful)

Most commercial airlines have strict size and weight restrictions for pets traveling in the cabin typically limiting in-cabin pets to those under 20 pounds. However there are some airlines that offer more flexibility for larger dogs.

Flying with a Large Dog in Cargo

If your dog is too large for cabin travel or you’re flying on an airline that doesn’t accommodate large dogs in cabin, cargo is your alternative:

• Delta – Accepts dogs starting at 50 pounds for cargo
• American Airlines – Allows larger dogs in cargo on domestic flights
• United – Has PetSafe program for dogs traveling as cargo

However, be aware that many pet owners experience more stress when their dogs travel in cargo due to separation and the different environment.

Preparing Your Large Dog for Air Travel

Before the Flight

1. Visit the vet

   • Get a health certificate (required by most airlines)
   • Ensure vaccinations are up-to-date (especially rabies)
   • Discuss any anxiety or motion sickness concerns

2. Acclimate your dog to their carrier/kennel

   • Start training weeks before travel
   • Make the carrier a positive space with treats and toys
   • Practice short sessions inside to reduce anxiety

3. Contact the airline in advance

   • Inform them about traveling with your large dog
   • Confirm all requirements and paperwork needed
   • Book well in advance as pet spots are limited

Day of Travel

1. Limit food and water

   • Feed your dog 4-6 hours before departure
   • Provide small amounts of water to prevent dehydration
   • Take your dog for a long walk before heading to the airport

2. Arrive early

   • Allow extra time for check-in and security
   • Find pet relief areas at the airport

3. Pack essentials for your dog

   • Favorite toys or blanket with familiar scent
   • Treats for positive reinforcement
   • Pee pads, paper towels, and waste bags
   • Leash for airport walks

Required Documentation

Most airlines require:

1. Health certificate issued by a vet within 10 days of travel
2. Proof of vaccinations (especially rabies)
3. Airline-specific pet forms
4. ID tags on your dog’s collar with your contact information
5. Microchip information

For international travel, additional documentation like pet passports may be required.

Carrier Requirements for Large Dogs

When traveling with your big dog in cabin, the carrier must:

• Be leak-proof and well-ventilated
• Allow your dog to stand, turn around, and lie down comfortably
• Fit under the seat in front of you (for commercial airlines)
• Be properly labeled with your contact information
• Have secure latches

My Personal Experience Flying with My Large Dog

Last year, I flew with my 65-pound Golden Retriever on a semi-private airline. I paid for an extra seat, and while it wasn’t cheap, having my dog next to me instead of in cargo was worth every penny. He was calm throughout the flight because we had practiced with his carrier for weeks beforehand.

The key was preparation – getting him used to the carrier, having all paperwork ready, and arriving at the airport with plenty of time to spare. I also limited his food intake before the flight but brought his favorite treats to keep him happy during the journey.

FAQ About Flying with Large Dogs

Can I buy a seat for my large dog on a regular commercial flight?

On most commercial airlines, no. Dogs typically must fit in a carrier under the seat in front of you. However, semi-private airlines like JSX, Aero, and BLADE do allow you to purchase seats for larger dogs.

How much does it cost to fly with a large dog?

Costs vary widely:

• Commercial airlines typically charge $100-$125 each way for in-cabin pets
• Cargo shipping can range from $200-$500+ depending on size and distance
• Semi-private airlines may require purchasing an additional seat ($500+)

Is it safe for my large dog to fly in cargo?

While thousands of pets fly safely in cargo each year, there are risks including stress, temperature fluctuations, and handling. If possible, cabin travel is generally preferred for your pet’s comfort and your peace of mind.

Are there weight restrictions for dogs flying in cargo?

Most airlines accept dogs up to 100 pounds in cargo. For larger breeds, special arrangements may be necessary.

What if my dog is too anxious to fly?

Consult your veterinarian about safe calming options. For extremely anxious dogs, consider alternative travel methods like driving or pet transport services.

Bottom Line

Flying with a large dog requires more planning and often a bigger budget than traveling with smaller pets. Your best options for keeping your big dog in the cabin are:

1. Semi-private airlines that allow large dogs with purchased seats
2. Commercial airlines with more flexible policies like Alaska or United (on select routes)
3. Airlines without specific weight limits, focusing instead on carrier fit

Whatever option you choose, preparation is key. Acclimatize your dog to their carrier, have all documentation ready, and communicate clearly with airline staff about your needs.

With thorough planning and the right airline choice, you can enjoy traveling with your large canine companion while minimizing stress for both of you. Safe travels to all the big dog owners out there!
