What is a service animal?  Is a service animal the same as an emotional support animal, or a therapy animal?  How are they different?  Must a service animal be professionally trained?  These are just some of the questions people have about service animals.  Adding to the confusion is the fact that the rules for service animals under the Americans with Disabilities Act (ADA)  is not the same as the rules for support animals under the Fair Housing Act (FHA).  The following link provides a comprehensive list of frequently asked questions about service animals under the ADA, and was revised in July 2015:  http://www.ada.gov/regs2010/service_animal_qa.html
