Service animals and emotional support animals are different. Service animals are trained to help disabled people, while emotional support animals comfort and support mental health patients. The jobs don't require specific training.
Mental health experts regularly prescribe emotional support animals to people with anxiety, sadness, PTSD, and other psychiatric problems.
Dogs are frequent emotional support animals, but cats, bunnies, birds, and miniature horses can also be used. People choose animals based on their interests, living condition, and the advantages they get from them.
Emotional Support Animals: Emotional support animals help reduce loneliness, stress, and provide purpose and regularity. These animals' unconditional affection and friendship can improve mental health.
