How to Fly with a Large Dog

Airlines restrict the size of the dog you can bring aboard the cabin. Most airlines require that your dog be able to fit into a small carrier that stores underneath the seat in front of you. In practical terms, that means only small dogs can board the cabin as pets. Certain types of assistance animals, however, are exempt from these restrictions. 

Until January 2021, emotional support animals were exempt from these size and weight restrictions. Emotional support dogs were able to fly in the cabin free of charge, as long as they could sit in the space in front of you. On December 2, 2020, the U.S. Department of Transportation announced new rules that gave airlines the option to no longer recognize emotional support animals. As a result, airlines are no longer accepting emotional support animals on flights.  

There was better news for owners of psychiatric service dogs (PSD): PSDs are still allowed to board the cabin free of charge, and they are exempt from size restrictions applicable to normal pets. To fly with a psychiatric service dog, you will need to submit a special form to your airline in advance.

In this post, we’ll discuss how owners of large psychiatric service dogs can board flights and how to obtain a PSD letter if you are interested in qualifying for a psychiatric service dog. We’ll offer some helpful tips on how to improve your flying experience with your large PSD, especially if it’s your first flight together. 

Good News! All airlines still accept Psychiatric Service Dogs on all flights.

If you are interested in a Psychiatric Service Dog Letter, we would be happy to connect you with a licensed healthcare provider so they may assist you.

Tip #1 – Submit the Department of Transportation’s Form in advance 

As part of the recent changes in assistance animal regulations, all psychiatric service dog owners must submit a special form to the airline before their flight. The form requires the following information:

  • Certification that your dog has been trained to perform a task relating to your psychiatric disability. 
  • Name of the dog’s trainer (which can be yourself).
  • Date of vaccination for rabies. 
  • Name of your dog’s veterinarian (their signature is not required). 
  • Acknowledgment that your dog will be under your control at all times. 
  • Acknowledgment that you are responsible for damages caused by your dog.

The form must be submitted to the airline at least 48 hours before your flight. If you book a flight departing within 48 hours, you can submit the form at the gate.

Tip #2 – Qualify for a PSD Letter from a Licensed Mental Health Professional

To qualify for a psychiatric service dog, you must have a disability that meets the criteria set out under the Americans with Disabilities Act and the Air Carrier Access Act. That can mean a condition like depression, anxiety, phobia, PTSD, bipolar disorder, or another mental health issue that substantially limits a major life activity.

A licensed healthcare professional can help determine whether you meet this standard. ESA Doctors can connect you to a licensed professional that specializes in assistance animals. If you qualify, they will issue a signed PSD letter stating your eligibility for a psychiatric service dog. 

Note that for your dog to fully qualify as a PSD, it must also be trained to perform a task relating to your disability. A dog is not considered a PSD until it is:

  1. Fully trained to perform their disability-related task.
  2. Capable of handling itself in various public settings.

Tip #3 – Prepare your Psychiatric Service Dog for a successful flight well before the flight itself

1. Exercise your dog

Before the flight, thoroughly exercise your dog at a dog park to release any pent-up energy. This may allow your dog to sleep or rest on the flight. Keep in mind that the flight may be short, but your dog will have to wait an additional 1-2 hours while you pass security and wait at the gate. Flight delays are also common, as frequent fliers well know. 

On your return flight home, it is important to prepare ahead of time. If you are not familiar with the city you are flying to, you can look online for dog parks near a specific airport. Some airports also have specific areas for dogs to relieve themselves.

2. Do not over feed your dog

Do not over-feed your dog before a flight. Some dogs may experience motion sickness, and eating a large meal or too many treats before a flight can lead to an unpleasant experience. Try to also monitor water intake before and during the flight so that your dog does not have to relieve itself during the flight.

3. No new treats

Do not feed your dog any new treats within 48 hours of your flight. Before a flight is not the best time to experiment with changes in diet. A dog with an upset stomach can lead to a very unpleasant flight experience.

Tip #4 – Items you may want to bring with you to the airport

To keep your psychiatric service dog comfortable during the flight bring the following items with you:

  1. Blanket – laying down a familiar blanket with familiar smells from your home will establish a “bed” or “border” for your dog.
  2. Collapsible Bowl – your dog may need some water during and after the flight. Remember to limit the amount of water that you are giving to your dog.
  3. Pee Pads – just in case your dog really has to go, carry a pee pad with you so that your dog can relieve themselves after the security checkpoint or on the plane in the lavatory.
  4. Thunder Shirt – if your dog is not used to flying, you may purchase a thunder shirt to keep your dog calm in the cabin. Some dogs find comfort when wearing a thunder shirt.
  5. Tether, leash, or harness – remember that the airline can require that your dog be tethered, leashed, or harnessed at all times, so bring the appropriate equipment.
  6. Toys – bringing your dog’s favorite chew toy can ease their stress and occupy their minds.

Tags, ID cards, and vests – service dog accessories are not required, but airline staff can use them as one indicator that your dog is a psychiatric service dog.

Tip #5 – What to expect and do once you land at your destination 

Before you arrive at your destination, you should look for a pet relief area at the airport. Most airports will either have a pet relief area inside or outside of the airport. You can research the location of the pet relief area in advance by looking here: Airport Pet Relief Areas.

Not all airports have accessible pet drinking fountains. Remember to pack and use your collapsible bowl to give your dog some water and food. And don’t forget to give your psychiatric service dog a big hug and thank them for their service!

Which airline allows the biggest dogs in cabin?

Which Airlines Allow You to Fly with Large Dogs? Most airlines will accommodate your pet in one way or another. Some of the better, more cost-effective airlines include Air Canada, Air France, American, Delta, Emirates, Hawaiian, Lufthansa, Sun Country, Swiss International and WestJet.

Can I buy a seat for my large dog on an airplane?

You can't buy an extra seat for your dog. Traveling with a dog this way, essentially as carry-on luggage, usually incurs a lower fee than if it travels in the belly of the plane. And by the way, a pet in its carrier counts as your carry-on bag.

How do big dogs fly on planes?

You can usually fly with large dogs, although most airlines will make you check them as baggage or cargo (many airlines have a 75-pound limit on dogs checked as baggage – if your dog exceeds this weight, he'll need to fly as cargo).

Can you bring a 40 pound dog on a plane?

A 40-pound dog is indeed too large to travel in-cabin on most (if not all) airlines and will have to ride as cargo. Apart from very small pets, only trained and certified service or support dogs with legitimate documentation are sometimes allowed to accompany their owners in-cabin.
