When a well-trained and loving dog is brought to a retirement home, a nursing and rehabilitation facility, or a hospice, etc., it brightens the day of so many people, bringing positive companionship. That is why pet therapy dogs provide such an invaluable service, and there are many owners who would like their pets to participate. However, if someone is interested, it is very important to do some research first.
