It seems that sometimes dealing with one fear can affect others. One of my students told me that when his fear of the water left him, so did his fear of dogs. I asked him to write something about this. This is the lovely message he sent me, reproduced here with his permission.
Thank you for teaching me how to overcome my fear of water and learn how to swim the proper way. You have given me a lot of confidence and you are a fantastic and patient teacher. By learning to swim it has also helped me in many other ways, for example I have self confidence and have over come the fear of dogs too. Again I thank you very much you are absolutely wonderful and I wish you well and will send all my customers to you who want to learn how to swim,
