My therapist is going to write a letter stating I need a dog with me all the time, and she said I am allowed to take it to public places like Wal-Mart and such. Now, I've been doing some reading and it seems to me that in order to bring my dog to wal-mart, it has to be a certified Psychiatric Service dog. Once I get a dog, at what point does it turn from an Emotional Assistance Support Animal to a Psychiatric Service Dog, and how do I get it certified. If I DON"T have to get it certified and I CAN bring it to wal mart, should I just get an "Assistance Animal" Vest so that it is obvious that it is a assistance animal? Maybe the Laws are different in SC? I haven't been able to find Laws regarding assistance animals. Please write back and give me some guidance as to how this works.Thanks!
