An emotional support animal (ESA) is a companion animal that a medical professional has determined provides benefit for an individual with a disability. This may include improving at least one symptom of the disability. Emotional support animals, typically dogs, but sometimes cats or other animals, may be used by people with a range of physical, psychiatric, or intellectual disabilities. In order to be prescribed an emotional support animal the person seeking such an animal must have a verifiable disability. To be afforded protection under United States federal law, a person must meet the federal definition of disability and must have a note from a physician or other medical professional stating that the person has that disability and that the emotional support animal provides a benefit for the individual with the disability. An animal does not need specific training to become an emotional support animal
