Service dogs and handlers legal rights are covered under the American Disabilities Act. Service Dogs are NOT pets. They are highly trained dogs that are to mitigate a persons disability. They are NOT therapy dogs. Service Dogs are generally specific to one person or team. They are NOT required to have a vest or any specific identification. Some handlers don’t like others to know their specific disabilities and do not have to disclose them (Also covered under HIPPA law). There is NO ONE organization that Service Dogs must be registered to. Service dogs must be allowed into public areas with their handler. Trying to removing the service dog from the handler can be catastrophic in some instances. Service Dogs could be seen as Medical Equipment such as a pacemaker.
