Register & Certify Your Service Dog in Illinois
The truth is that you are not legally required to register or certify a service dog in Illinois or any other state in the US. (*exception: New York City service dogs must be licensed by the city’s Department of Health). Service dogs are protected under the ADA, Americans with Disabilities Act. Registration and certification is possible – but completely optional – and does not convey any legal rights under the ADA or the Department of Justice. Read more here:
