What is a service animal?
Under the ADA, it is generally a dog individually trained to do work or perform tasks for a person with a disability. In some cases, separately defined provisions apply to miniature horses.

Service Animal Rights & Access
SARA is an independent educational resource. We do not issue government credentials, certify animals, or operate a government registry.
Under the ADA, a service animal does not need certification, registration, an ID card, or a vest. A private document does not create access rights or replace applicable local dog licensing and vaccination rules. Read the U.S. Department of Justice FAQ.

Comfort, therapy, emotional-support, and companion animals are not service animals under the ADA solely because they provide emotional support. Other laws may apply in particular settings.
Handlers remain responsible for care, supervision, and control of their animals, along with generally applicable local licensing and vaccination requirements.
When the service an animal provides is not apparent, ADA-covered entities may ask only:
They may not request documentation, ask about the person’s disability, require a demonstration, or charge a service-animal surcharge. Access rules can vary by setting and state or local law, so use official guidance for the situation at hand.
No. The ADA does not require a vest, ID tag, or special harness. A vest alone does not determine whether an animal meets the ADA definition.
In limited circumstances, including when an animal is out of control and the handler does not regain control, or when it is not housebroken. The person must still be offered access without the animal when appropriate.
