App_mode=Display_Statute&Search_String=&URL=0400-0499/0413/Sections/0413.08.htmlIt defines a service dog as: Service animal” means an animal that is trained to do work or perform tasks for an individual with a disability, including a physical, sensory, psychiatric, intellectual, or other mental disability.The statute also states: The crime-deterrent effect of an animal’s presence and the provision of emotional support, well-being, comfort, or companionship do not constitute work or tasks for purposes of this definition.

Service Animal Defined by Title II and Title III of the ADAA service animal means any dog that is individually trained to do work or perform tasks for the benefit of an individual with a disability, including a physical, sensory, psychiatric, intellectual, or other mental disability.

I'm hoping it's the latter.If you can't handle living in the privacy of your home (or rental) without an animal, you probably need to be a psychiatric care unit.

Common terms for these animals: Guide Dog or Seeing Eye Dog, Hearing Dog or Signal Dog, Psychiatric Service Dog, Seizure Response Dog, SSigDog (Sensory Signal Dog or Social Signal Dog).

I'm not sure where I am going with this, but what are the thoughts on someone having a need for an emotional support animal(prescribed by psychiatric doctor) and carries a firearm?

Scott Peck suggests that "Evil can be defined as a specific form of mental illness and should be subject to investigation like other major psychiatric disease."  

When she got a service cat to help with psychiatric problems, that was too much for me--yes, I determined I didn't want to be part of that situation, so haven't talked to her since.

@Alvin Sylvain  from my reading of the ADA and FHAA there is a clear distinction between a Service Animal and an Emotional Support Animal (EAS) the EAS does not always have the same protections under the law, to afford the same protections there needs to be "a Psychiatric need"  the words specifically used, and it went on to say you could require proof from a medical or psychiatric professional.   

Legally speaking; A service animal means any dog that is individually trained to do work or perform tasks for the benefit of an individual with a disability, including a physical, sensory, psychiatric, intellectual, or other mental disability.

Considering this particular tenant has some underlying psychiatric issues, there is a possibility  that they may not want to move when given such notice.
