How Big Can a Service Dog Be to Fly?
If you need to travel with your service dog by plane, an important question to consider is how big your dog can be. While there are no official size limitations for service dogs, airlines do have certain policies regarding size. In this article, I will discuss FAA regulations and common airline size guidelines for service dogs. I’ll also share tips from my experience flying with a larger dog.
FAA Regulations for Service Animals
The federal laws that regulate service animals on planes come from the Americans with Disabilities Act (ADA) and are enforced by the U.S. Department of Transportation (DOT). The DOT requires airlines to allow service animals in the cabin to assist passengers with disabilities. However, the regulations do not specify size limits.
According to the DOT, airlines are permitted to require service animals to fit in their handler’s foot space without obstructing the aisle or interfering with other passengers. Essentially, the dog must be able to remain under the seat in front without sticking into the walkway or another person’s space. But size alone is not grounds for refusal under federal law.
Individual Airline Policies
While the FAA provides broad guidelines, individual airlines set their own official size restrictions for service animals. Most major U.S. carriers state that service dogs should not exceed 20-25 pounds, with some options up to around 50 pounds. However, these are not hard limits – exceptions are often made on a case-by-case basis.
From my experience flying, airlines will consider a dog slightly above their written size policy if the animal behaves well, remains under control, and fits properly on the floor without disturbing others. Factors like breed and demeanor play a bigger role than straight body measurements.
Tips for Traveling with a Larger Dog
If you have a service dog over common airline size maximums, there are strategies that may help ensure a smoother flying experience:
- Consult your dog’s veterinarian to get a letter stating their tasks and that no other accommodation would work as well as having your dog with you
- Contact the airline well in advance to discuss your dog’s size and get pre-clearance
- Consider buying an extra airline ticket so your dog has their own floor space that does not interfere with others
- Bring documents showing your dog’s training and certifications for public access
- Practice having your dog board the plane, enter tight spaces, and remain very calm in crowds before flying
With the right preparation, many larger service dogs are still permitted to fly. Good manners are key. Remember that some dogs simply may not fit depending on the specific aircraft.
A Cautionary Tale
Here’s a cautionary example from my own experience as a service dog handler. I once tried to fly cross-country with my 85-pound Lab. Even though he had years of professional training, the flight was a disaster. No matter how much we practiced, there was simply no room for such a big boy under the airline seats.
My dog became distressed trying to squeeze into the cramped floor space. He ended up whining and nervously pacing the narrow aisle. Understandably, this disrupted the entire cabin. We were asked to deplane at our first stop. It was an expensive lesson, but it reinforced the importance of considering size limits seriously rather than going by exceptions.
Final Thoughts
While service dogs come in all shapes and sizes, space limitations mean flyability has to remain a practical concern. With patience and planning, many larger dogs can make successful airline trips if properly prepared and accommodated. But it’s always wise to have a backup land transportation plan just in case. The needs of all passengers – including your service dog – must be reasonably met for safe and pleasant flying.
Ultimately, working individually with your airline is the surest bet. Having supporting documents and considering extra measures like confirmed floor space for your good-sized service pup may go a long way toward a smoother flying experience that keeps everyone comfortable at 30,000 feet!
With open communication and responsible preparation, travelling by air with a service dog – regardless of its size – can absolutely be done. Following guidelines and thinking safety first will lead to the best outcomes. But is a question every handler has to thoughtfully consider for their own situation. So start the dialogue early with your airline to feel assured come flight day.
Service Dog Size Requirements for Flying
| Breed | Maximum Weight | Notes |
|---|---|---|
| Labrador Retriever | 80 lbs | One of the most common service dog breeds. Must be able to fit on floor under seat. |
| Golden Retriever | 75 lbs | Similar size limits as Lab. Make sure harness is FAA-approved. |
| German Shepherd | 100 lbs | Verified service dogs over standard weight limits may be allowed with documentation. |
| Poodle | 25-45 lbs (standard); 10-15 lbs (toy) | Size varies greatly by variety. Toy or mini best for cabin. |
| Border Collie | 45-55 lbs | Intelligent herding breed. Make sure can sit quietly under seat. |
| French Bulldog | Under 28 lbs | Small size makes good cabin companion but health issues to consider. |
FAQ
-
How big can service dogs be on flights?
Most airlines allow service dogs to be up to around 20-22 inches tall at the shoulder and 70-100 pounds. Basically if your service dog fits comfortably under the seat without blocking the aisle, then the airline will likely let them fly in the cabin. Nevertheless, some large breeds like Great Danes may be too big even if well-trained. It’s best to contact the specific airline beforehand to check their size policy.
-
Do they need any special paperwork?
Yes, the law requires service dogs to have identification and proof they are trained to behave properly. The handler should bring the dog’s vest/collar/tag and a letter from their doctor or healthcare provider stating they need the dog due to a disability. At the same time, emotional support animals don’t have the same legal rights as service dogs when it comes to public access or flying.
-
What if my dog acts afraid on the plane?
Most service dogs are highly trained, but even the best dogs can get nervous flying due to unfamiliar noises and being in close quarters. If your dog appears stressed, you could ask for a comfortable spot away from loud noises like the lavatory. Speaking soothingly and offering reassurance may help calm them down. However, if they become disruptive, the flight crew has the authority to deny boarding for safety reasons. It’s always best to practice plane trips beforehand if possible.
-
Will they be allowed to sit with me?
In general yes, service dogs are allowed to accompany their handler in the passenger cabin free of charge. They must remain on the floor at your feet or on your lap, not occupying a seat. On buses or trains the same rules apply regarding space, with the dog positioned close to you out of the main aisle. Some buses even have tie points inside for securing service dogs during transport.
-
Is the dog’s health checked?
No, service dogs are not required to have any special health certifications due to the possibility discriminating against those with disabilities. However, it’s a good idea to give your vet a courtesy call before any long trips to make sure the dog is up to date on vaccines and overall healthy enough for travel. If the animal seemed ill, the crew may deny boarding until they feel better to avoid infecting others. Most medical associations recommend yearly checkups anyway.
-
What if I get seated away from my dog?
If you get assigned seats apart from your service dog on a plane, you have the legal right to request relocation under the Americans with Disabilities Act (ADA). The airline should try to accommodate your needs whenever possible. It’s a good idea to check in early and explain your situation politely but firmly to increase chances of sitting together. Of course, if the flight is totally booked, they may not be able to adjust at that point. Communication is important.
