An emotional support animal (ESA) is a companion animal that provides therapeutic benefit, such as alleviating or mitigating some symptoms of the disability, to an individual with a mental or psychiatric disability. Emotional support animals are typically dogs and cats, but may include other animals. In order to be prescribed an emotional support animal by a physician or other medical professional, 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.
