Service Animals under the ADA
The U.S. Department of Justice (DOJ) defines "service animals" under the Americans with Disabilities Act (ADA) as "dogs that are individually trained to do work or perform tasks for people with disabilities."
When it is not apparent as to why the person need the animal, the DOJ allows 2 questions:
1. Is the dog a service animal required because of a disability?
2. What work or task has the dog been trained to perform?
