For people who are physically disabled, they can take specially trained animals to do many disability tasks like pulling or pushing something. These animals also provide a guide to blind people. Services are licensed to go in places with their owner but ESAs are not allowed. ESAs are not specially trained for a physically disabled person so they are not allowed at schools, universities, and traveling. In case of mental disorder issues, you get a special license to get your ESA pet with you at school, university or hospital otherwise everyone has not allowed doing so.
