This aids self-recovery. Pet therapy uses the unconditional love of the animal for a human being. Animals do not have reservations about making friends. They reach out to humans of all races, ages, sex and language. A pet is a universal adapter.
Animals are simple minded in giving their love and expecting almost nothing in return.
Before such pets are used for pet therapy, they need to be trained. Possible scenarios are enacted out with the trainer to expose the dog to different situations. Appropriate responses are taught to the dog. This is to prevent the animal from panicking when it faces a real situation. Animals who don't know how to react will show either a fight or flight response.
