Certainly in the research I've looked at, they pretty well go right down the checklist of issues you mentioned: anxiety, depression, anger, and so on.
So the last question I'll ask, whether we're talking about equine-assisted therapy or therapy using other animals, such as dogs, is what your timeline is. Are we talking about a year, five years, ten years? If the research is heading in the right direction—and it looks as though it is—are you looking at pilot projects?
