There isn't any special licensing or anything required for a service animal either. I worked with a lady who had a "service" dog who supposedly helped her with her balance. I can tell you from being around her a lot, the need was almost totally fake. The dog was trained by her to do just the basic stuff like "sit' and "stay" which the dog didn't necessarily follow anyways. The dog pretty much was a pet and the "balance" help was totally fraudulent. Yet she was able to take the dog anywhere she went, the swimming pool, restaurants, fancy hotels, etc. The dog was a nice dog though and no aggressive bone in her body. The lady, on the other hand, was very aggressive with many mean bones in her body.
