These days, specially trained animals are used to provide support to people with all kinds of physical, mental and emotional issues. These animals can help people to overcome the difficulties that their disabilities cause or just provide comfort or support during difficult times. They enable people to lead a happier and more independent life. Dogs often make the best support animals, as they are intelligent and easy to train. Therapy dogs, as their name suggests, are much like their human namesakes, and can be a huge benefit in the lives of people in need of company or affection.
