service dogs bipolar

My dog described as "service animal"?
I have major depression, bipolar disorder and anxiety disorder and have been living for myself for about 15 years since I was thirteen. My doctor always told me that dog, so do not be so lonely since no I have family or friends because of my depression. I really want an animal that can help me and be there for me. Is it possible that if I buy a small breed animal as the Shih Tzu and make it a service animal or therapy so he can go to any part of me? How do I apply for it? Do I need a permit my physchiatrist? Thank you!
The critical points to take a "service dog" are: 1. You must be specified as "disabled" according to the guidelines established by the U.S. Justice Department under the Americans With Disabilities Act, and 2. Your dog must be individually trained to perform work or perform tasks to mitigate the effects of their disability. If you can meet both requirements, your dog is not a service dog. However, you may be able to have your dog classified to support an "emotional animal (SEC), which are allowed in" no company housing, but the driver does not have public access rights with the animal. Your doctor or psychiatrist should be able to provide information for your dog recognized as one of the ESA. As a note to clarify: There is no legal requirement for any type of identification vest, badge, or belt for any legitimate service animal. There are some services providers animals make art special identification number, but the law does not require a controller to either use or display. The law also requires no "certification" and the law does not allow anyone to request any type of "ID card" or "paperwork" that needs to be demonstrated, access to public. The issues of access only legally be asked of a service dog handler are: 1. It is a service dog? 2. The dog is necessary because of a disability? 3. What mitigating task (s) is the dog trained? That's all. Anything else is a violation of civil rights managers and can lead to a costly trial. No ID, no paperwork, no jackets required.
