I have no idea how old you are, why you want one, what tasks you want it to perform and where you live.

 I have no idea how old you are, why you want one, what tasks you want it to perform, and where you live. Here's some info: Service dogs are trained very specifically for one person and that determines how it is trained. You could start inquiring with your psychiatrist (although they don't get educated on such matters). You could call a psychiatric hospital. Whatever psychiatric condition you have will also help: there are online groups for PTSD, schizophrenia, depression, etc. Perhaps you can get a lead there Usually you are assessed for what needs you have, based on that a breed is chosen. Then you get a dog and work with a trainer to get the right skill set to help you.
