Service animals are very well-trained to perform physical tasks that you cannot perform due to a certain disability. These include pushing wheelchairs, opening doors, or even detecting blood sugar levels. These animals are protected under the Americans with Disabilities Act (ADA) that allows the owner to take these service dogs with them wherever they go, irrespective of any restriction. Unlike emotional support animals, service animals do not require certain documentation like an realesaletter. You can take these animals anywhere and their performing their duties is enough to prove that they are service animals.
