All you need is a Doctor's letter stating your condition and a SUPPORT ANIMAL would be very important for your well being. I finally got a dog after showing my Landlord the letter and he could not say NO. You can train your dog to go potty on a pad, that's what I did because I was not well enough to walk her. She is my total Support! No family near, and I can't tell you how fortunate I am to have Missy Bojangles. She goes everywhere with me in a Luggage Cart I bought for her, the Doctors, Emergency Hospital, absolutely everywhere>
