Therapy Dogs International (TDI®) is a volunteer organization dedicated to regulating, testing and registration of therapy dogs and their handlers for the purpose of visiting nursing homes, hospitals, schools, care facilities and wherever else therapy dogs are needed! We have volunteer dogs and their handlers in all 50 States as well as Canada.Whether they're working with a child who is learning to read, visiting a patient in a hospital or a senior in assisted living, therapy dogs and their owners work together as a team to improve the lives of other people. A dog can provide a valuable sense of reassurance, joy, and calmness to people experiencing stressful, lonely or depressing situations in their life.
