Emotional support animals are not protected by the ADA. Only trained service animals. If you have a disability with a registered service animal then simply provide documents to eliminate any argument or discussion about the legitimacy of your animal and your needs. They don’t need to know about your disability, but providing documents that a service animal will have is sufficient and can’t be refused under the ADA. **I’m NOT saying emotional support animals aren’t legitimate, because I truly believe they are, but unfortunately they are not protected under the ADA.
