I am going to explain the difference between a service dog, a therapy dog, and an emotional support animal, as it seems that people don't know the difference. Only one type has FULL access in public and those are service dogs. You have to have a DISABILITY (not a diagnosis) and the dog must help relieve symptoms of the disability but performing a trained task. These dogs get EXTENSIVE training, like around 1000 hours minimum of training. These dogs do not have to registered with any organization.

A Therapy dog is a dog that is trained to go to certain areas. They are used to HELP OTHER PEOPLE, such as in hospitals, schools, etc. They do have to be registered by a therapy dog organization and tested thoroughly before being able to have partial access to a certain event, etc.

An emotional support animal is an animal that does not have any prior training or do specific tasks, but help relieve the symptoms of a DISORDER (not a disability) at home. They do NOT have any special public access, but are protected in the housing act (allowing them in no-pet rentals).
