If you have a dog, someone has probably called them “basically a service dog” or asked whether they are an emotional support animal. The terms sound similar, but the differences matter. They affect where a dog can go, what businesses can ask, what landlords may consider, and how to spot fake paperwork.
We reviewed current ADA, HUD, and Department of Transportation sources to keep this practical. This is not legal advice, but it is a clear starting point.
What Is a Service Dog
A service dog is a dog individually trained to do work or perform tasks for a person with a disability. The disability can be physical, sensory, psychiatric, intellectual, or another mental disability, and the task must be directly related to that disability. ADA.gov defines service animals this way, and the same task-based standard appears in the DOJ’s service animal FAQ.
Under the ADA, service dogs are generally allowed in public places where their handlers go, including restaurants, shops, hotels, schools, and hospitals. There are narrow exceptions. ADA.gov says a service animal can be excluded if its presence would fundamentally alter the setting, such as a sterile operating room, or if the dog is out of control or not housebroken.
When the dog’s job is not obvious, staff may ask only two questions: is the dog required because of a disability, and what work or task has the dog been trained to perform? They cannot ask for documentation, require a demonstration, or ask about the person’s disability. The ADA also does not require a vest, tag, harness, or special ID. The training is what matters.
Air travel has its own rulebook under the Air Carrier Access Act. The Department of Transportation says airlines may require service animal forms about a dog’s health, behavior, training, and relief needs on long flights. The final DOT rule published in the Federal Register PDF hosted by GovInfo explains those forms and denial rules.
What Is an Emotional Support Dog
An emotional support dog, often called an ESA, comforts a person with a mental or emotional disability. ESAs are not required to perform a specific trained task. Their presence and companionship are the support.
That distinction is the whole point. The DOJ says emotional support, therapy, comfort, and companion animals are not service animals under the ADA when their only role is comfort. That means an ESA does not have the same public access rights as a service dog. Restaurants and stores can deny entry to an ESA if pets are not allowed.
Housing is different. The Fair Housing Act still prohibits disability discrimination in most housing, and HUD says disability is one of the protected categories under the Act. Assistance animal requests can still be part of a reasonable accommodation issue, but the details became less settled after HUD withdrew prior guidance. HUD’s September 17, 2025 Notice of Withdrawal of FHEO Guidance Documents withdrew both FHEO Notice 2013-01 on service and assistance animals in housing and FHEO 2020-01 on animal accommodation requests under the Fair Housing Act.
That does not mean the Fair Housing Act disappeared. It means the detailed HUD guidance many landlords used for documentation, timing, pet fee, and assistance animal questions should no longer be regarded as authoritative. If you have a specific housing dispute, talk to a fair housing organization or attorney.
Air travel changed too. The DOT final rule says emotional support animals are not service animals under the Air Carrier Access Act. Airlines can now classify ESAs as pets, with normal pet fees, carrier rules, and size limits. The final rule PDF explains the specific changes.
What Is a Therapy Dog
A therapy dog is trained to comfort multiple people in settings like hospitals, schools, nursing homes, and disaster relief environments. Therapy dogs are not assigned to one disabled handler the way service dogs are. They usually visit through organized programs with a handler.
Therapy dogs do not have ADA public access rights just because they are therapy dogs. Whether one can enter a hospital, school, library, or care facility depends on that institution’s policy. There is no single federal therapy dog license. Private organizations set their own screening, handling, insurance, and visit requirements. The AKC keeps a list of recognized therapy dog organizations for owners who want to explore volunteer work.
If you want to understand your dog’s behavior before considering volunteer work, start with the basics of reading your dog’s body language. A therapy dog needs more than friendliness. They need stability around strangers, medical equipment, noise, and unpredictable movement.
The Certification Scam Problem
This is where the confusion gets expensive and harmful.
A large industry sells fake service dog vests, registration numbers, ID cards, and instant ESA letters. Many sites look official or claim federal recognition. That is not how this works.
The federal government does not maintain a national service dog or ESA registry. For ADA public access, the DOJ is direct: online service animal certificates and registration documents do not convey ADA rights and are not recognized as proof. Staff also cannot require those documents because the ADA does not make them a condition of entry.
For housing, be careful with any site promising instant ESA approval after a short quiz and payment. A legitimate request usually needs disability-related support from a provider with real knowledge of the person’s situation.
The harm goes beyond wasted money. Fake credentials make businesses more suspicious, and that suspicion often lands on legitimate handlers. It also puts unprepared pets into places where they may be stressed, disruptive, or unsafe.
How to Know Which Category Applies
If you have a disability and your dog is trained to perform specific tasks that help with that disability, your dog may qualify as a service dog under the ADA. People with disabilities can train their own service dogs. A professional program is not required.
If you have a mental or emotional disability and a licensed health care provider supports the dog’s role in your housing accommodation request, your dog may fit the ESA category. That does not create restaurant, store, or airline access rights.
If your dog is calm, steady, well handled, and comfortable with many kinds of people, therapy work may be worth exploring through an established volunteer organization.
The Bottom Line
Service dogs perform disability-related tasks and have broad public access rights under the ADA. Emotional support dogs may be part of a housing accommodation request, but they do not have ADA public access rights and are no longer classified as service animals on flights. Therapy dogs comfort multiple people through facility-approved programs and do not have automatic public access rights.
There is no federal registry, no government-issued certification card, and no online registration that legally turns a dog into a service dog, ESA, or therapy dog. If a website says otherwise, close the tab.
If you are facing a real access, housing, or air travel issue, get situation-specific help from the relevant agency, a fair housing office, or an attorney.
