Service Dog Laws

The federal, state, and city regulations about service dogs.


Service Dog Laws

This page attempts to summarize all the various laws and regulations. The wonderful American Veterinary Medical Association has also put out a draft 16-page "white paper" that goes into more detail, if you're interested.

The Americans with Disabilities Act (ADA) is the main law governing Service Dogs, except on airplanes because “the Air Carrier Access Act is the Federal law that protects the rights of people with disabilities in air travel”.[1]


1 - The Americans with Disabilities Act (ADA): 

The law says that a Service Dog must be trained specifically for a person with a disability. That means it can’t just be a general-purpose assistance dog, but rather it must be trained specifically for one person.The person who is getting the dog must have a disability that rises to a level that the Americans with Disabilities Act considers a disability. A good rule of thumb is that if a person cannot work, then they’re disabled. (This is not always the case, but it’s a good general rule to follow.)

The dog must be trained to do a “task.” The term is not strictly defined, but three of the most clear-cut tasks are helping lead a person who is blind across the street, alerting a person with severe diabetes that their blood sugar has dropped dangerously low, or picking up items for someone with limited mobility.

There are no limits to the size or breed of dog that may be used as a Service Dog. However, one may not have a service cat or any other animal (except for miniature horses).

If you live in the United States and have a disability, you benefit from the forward-thinking Americans with Disabilities Act. Most countries, unfortunately, do not have such broad protections. many only legally recognize service dogs for people who are blind. There are a few, however, who legally recognize alert dogs (for diabetes and epilepsy), mobility dogs (for pulling wheelchairs, picking up dropped items, turning on/off lights), and signal dogs (for the deaf), but very few recognize service dogs for autism or psychiatric disabilities such as Post Traumatic Stress Disorder. Restrictions. The rest of the law says (generally) that a Service Dog must be well behaved and must be leashed. Other requirements are that the dog is in control and that the dog is housebroken. These two points might seem obvious, but when you get into the issue of fake Service Dogs, these two elements can be helpful in demonstrating the difference between a real Service Dog and a fake one.

The law goes into where the dog and handler can go, which is defined as "where the public is normally allowed to go". This wording implies that the handler can bring the dog into businesses, nonprofits, churches, and even schools.

The law also goes into what a staff person can ask about the dog, which are two questions - one is to confirm that the dog is required because of a disability, and the other is to ask what task the dog performs.

The federal law does not get into whether there are exceptions for service dogs in training, so that is sometimes a gray area, depending on your state. A good rule of thumb is to follow the law that Minnesota passed in 2015 (256C.02 Public Accommodations), which states, "Any person training a dog to be a service dog shall have the right to be accompanied by a service dog... The service dog must be capable of being properly identified as from a recognized school for seeing eye, hearing ear, service, or guide dogs." The term "recognized school" can be interpreted being registered with the Secretary of State as a local nonprofit.

2 - Fair Housing Amendments Act

Here are the federal memos defining the statutes about housing and service dogs, written in 2004, 2011, 2013, but basically, this housing law applies to renters, and it affirms that landlords have “obligations to make reasonable accommodations for assistance animals”.[3] In layman’s terms, this law affirms that someone with a disability can keep their Service Dog with them in a rented house or apartment, even if the landlord doesn’t allow pets there.

3 - Air Carrier Access Act

A third federal law addresses airlines, and this law has very different wording. It applies to two groups of people: those with disabilities who have a “Service Animal,” and those without disabilities who have an “Emotional Support Animal”.[4]

  • Emotional Support Animals on Airlines: As defined by the Air Carriers Access Act, an “Emotional Support Animal” is “ animal used for emotional support (which need not have specific training for that function)”.[5] In other words, anybody can have an Emotional Support Animal; all they require is a recent note from their doctor (written within the last year) saying that they need one. Then they can fly with the animal at their feet for free, instead of paying extra money to have the animal transported in the cargo hold. Someone traveling with an Emotional Support Animal must provide the letter from their doctor before they can fly.A weird fact about the airlines’ definition of “Emotional Support Animals” is that these animals don’t have to be dogs. Whereas by law a “Service Animal” has to be a dog (or a miniature horse, oddly enough), there are no such restrictions about what can serve as an Emotional Support Animal on airlines. The Department of Transportation even uses the phrase “cats, monkeys, etc.” in the aforementioned “Guidance Concerning Service Animals in Air Transportation.” This loophole is why someone bringing a cat or a pig or a chicken (or even a dog) on board an airplane as an Emotional Support Animal occasionally makes the news. And because there are no rules regarding the training of these animals, people sometimes get confused and think they are poorly trained “Service Animals.”

  • Service Dogs on Airlines: In a confusing move, at least as of 2/15/17 (when I'm writing this), airlines have split Service Dogs into two categories:

    • Service Dogs for Physical Disabilities: This category is easy—if a person has a Service Dog for their physical disability (including diabetes, epilepsy, mobility issues, etc.), they can just go through security like anyone else and then have their dog at their feet during the flight. People in this category do not need to provide any documentation proving that their dog is a Service Dog.

    • Psychological Service Dog: In regard to air travel, “Psychological Service Dogs” aren’t actually “Service Dogs” at all. It’s a very odd rule, but it means that Psychological Service Dogs—which, according to the airlines’ rules, include PTSD Service Dogs—are not considered Service Dogs. It’s confusing and unfortunate, especially if someone who wants to fly is not aware of this restriction beforehand. If a person has a Psychological Service Dog and wants to fly with them, the easiest way for them to do so is to get a letter from their doctor saying that they need an Emotional Support Dog. They will need to show this letter before they’re able to travel with their dog. Unfortunately, if you show up at the airport with a PTSD Service Dog and do not have a doctor’s letter stating that it’s an Emotional Support Dog, the dog will have to be crated in the cargo area of the plane, and the handler will have to pay a fee for the dog to fly.Why do the airlines have these different (and confusing) regulations? They don’t specify, but I think a clue can be found in the Air Carriers Access Act’s term “emotional support.” For people with high levels of anxiety, having an Emotional Support Animal who genuinely calms them down is pretty important in a crowded airplane thousands of feet up in the air. This relaxes and soothes the passenger and, thus, makes things better for the flight crew and surrounding passengers. So it is to the airlines’ advantage to allow Emotional Support Animals for this reason. However, it would be easy for people to take advantage of this, so the airlines put some minor restrictions in place. They’re basically saying, “If your pet will keep you calm you can bring it with you and have it lie at your feet. But we don’t want this privilege to be abused, so we insist that you get a recent doctor’s note.” Just the fact that people have to get a doctor’s note cuts down considerably on the number of people who would go to the trouble of doing so if they didn’t really need an Emotional Support Animal. And for people who have a Psychological Service Dog, it is well worth this minor inconvenience to have their Service Animal travel with them. What about service-dogs-in-training? The answer depends upon the airline and right now, Alaska Airlines is the only one that specifically publishes a policy allowing service-dogs-in-training on planes. The Department of Transportation's Office of the Secretary, in its "Guidance Concerning Service Animals in Air Transportation" 14 CFR Part 382, docket number OST-2003-15072, gives the following guidance: "Although 'service animals in training' are not pets, the ACAA does not include them, because 'in training' status indicates that they do not yet meet the legal definition of service animal. However, like pet policies, airline policies regarding service animals in training vary. Some airlines permit qualified trainers to bring service animals in training aboard an aircraft for training purposes. Trainers of service animals should consult with airlines, and become familiar with their policies."

City Laws

  1.  City Laws for the Handler: Most cities in the United States require that all dogs have a license. In the spirit of “setting up the handler for success,” it’s nice to help the handler get a dog license for their city. We usually go to the city’s website, print up the application, photocopy the dog’s rabies certificate and the veterinarian record stating that the dog is spayed or neutered, and then mail that packet to the future handler. We also include a stamped envelope that is pre-addressed to the city so the handler can just sign the application and mail it in. In some places, if the dog is microchipped, the city will offer a lifetime license for the dog.

  2. City Laws for Nonprofits: Where we live, the city requires our nonprofit to fill out a form and then have 75% of nearby neighbors sign it, thus approving that they are okay with the idea. We are now allowed to have up to five dogs in our home at a time, although we usually only have three (two in training, plus one is our pet dog). The city sends out an Animal Control officer once a year for a surprise investigation to make sure our home is following all codes and that all the animals are well-kept and licensed. 

There are a lot of guidelines and rules about service dogs, so I’m going to start by making some broad generalizations and then get into the complexities, exceptions, and shades of gray. Note that some of these items are actual laws (generally federal laws) but others are just our guidelines and recommendations. Note, too, that I am not a lawyer, but rather, the following is my understanding of the applicable laws and regulations.

While service dogs are allowed in most places, the law says they aren’t allowed to block an aisle or go up onto seats. We also recommend that handlers don’t take their dogs to swimming pools because of possible cleanliness issues, to live performances because of the dog’s potential to disturb others, or to movies because the noise level and tight quarters are challenging for the dogs.


The vocabulary about dogs that help people is a little confusing, and many people (incorrectly) use the following terms interchangeably. 

  1. Service Animal (Service Dog): In layman’s terms, a service dog is trained for a person with a disability, and it has been trained specifically for that one person.The specific definition, however, is federally controlled. “Service animals are defined as dogs that are individually trained to do work or perform tasks for people with disabilities”.[6] The law also states that service animals must be trained to perform at least one task specifically for their handler, and in order for someone to get a service dog, they must have an ADA-specified disability. A good rule of thumb is that if a person can't work (or can't drive), then their disability rises to the level the ADA requires. So, being on SSI or not being able to get a driver's license are pretty good markers.Airlines use a different and much broader definition of “Service Animal,” which will be described later in the chapter under the Air Carrier Access Act. It's confusing that the airlines use the same word with different definitions, but that's the way it is.

  2. Assistance Animal: In layman's terms, an assistance animal is the same thing as a service dog. The dog assists its handler in some way. This is a broader term that can also apply to Guide Dogs.The term “Assistance Animal” is legally defined under the Fair Housing Act as “...only dogs, and [they] further define ‘service animal’ to exclude emotional support animals”.The term “Assistance Animal” is legally defined under the Fair Housing Act as “...only dogs, and [they] further define ‘service animal’ to exclude emotional support animals”.[7]

  3. Guide Dog: A Guide Dog, also known as a “Seeing Eye Dog,” is a certain kind of service dog: specifically, one that is trained for a person who is blind. “Guide Dog” doesn’t have the same kind of federal legal definitions that the other terms do, so it’s not used as often. However, Guide Dogs go through lengthy and rigorous training.

  4. Therapy Dog: This is a confusing term because it sounds like the others, but it doesn’t actually confer any special rights. While a Service Dog is trained for one specific handler and must perform at least one task for that person, a Therapy Dog is used by a group of people. You might see children reading to them in libraries, or they might visit elderly people in nursing homes or patients at a hospital. More recently, they are often taken to college campuses or places where something tragic has happened so they can provide support and comfort. There are no laws regarding the training of Therapy Dogs, but there are specific courses that handlers can take if they’d like to get their dog certified to perform this work.Although “Therapy Dog” is not a federally defined term, one court provided this specification: “Unlike service dogs, therapy dogs are not legally defined. Therapy dogs undergo and pass evaluations according to standards set by national organizations. They have been trained as a team with their owner/handler to provide therapeutic comfort or emotional support to people”.[3]In other words, while a Service Dog can only be owned by someone with a disability, anybody can own a Therapy Dog. While there are no laws to define what type of training Therapy Dogs must have, many places won’t allow Therapy Dogs unless they have undergone special training and achieved certification. Most handlers who want to volunteer just train their pet dog really well and then get it certified by a therapy dog organization such as the American Kennel Club or PetPartners. However, a Therapy Dog does not have the right to enter public buildings like a Service Dog does. Only in specifically defined situations can a volunteer bring their Therapy Dog to a hospital, library, or other public space.

  5. Emotional Support Animal: This last vocabulary term is used primarily by airlines, and it’s confusing enough that I’ll refer you to the Air Carrier Act section, lower down on this page, where the term is described in detail.Most people don’t know the difference between a Therapy Dog and a Service Dog, and in most cases, there’s no need to tell them the difference. We tell handlers that if someone refers to their Service Dog as a Therapy Dog, they don’t necessarily have to correct them. The exception would be in cases where there are legal ramifications—for instance, if a handler wanted to bring their Service Dog into a restaurant or other public building.
