The geriatric population suffers from various physical and mental ailments apart from their day-to-day challenges. The focus of the treatment or the management for the same aims at not only reducing the health issues but also improving the quality of life. Animals have always been a support for older people either in terms of providing companionship as pets or serving as working animals to ease the tasks. Animal-assisted therapy is the newer form of management that has been growing to manage senile diseases and promote the well-being of people. The present chapter will address how therapy animals can help fight the aging issues while focusing on the better well-being of the geriatric population. The discussion of literature exploring the positive effects of animal-assisted therapy on certain mental health conditions of the geriatric population will provide a brief idea of how therapy animals play a key role in the field of health care.
