This book provides an up-to-date overview of the current knowledge and research concerning domestic pets as sentinels, forecasters and promoters of human health. Written by leading specialists in the fields of medicine, veterinary, environment, analytical chemistry, sociology and behavioral science, this volume provides a comprehensive understanding of the capabilities of pets in what regards to human health. The first seven chapters are devoted to the use of pets as sentinels for their human companions, in terms of exposure to different classes of environmental chemicals. The following five chapters address the use of pets as models for human diseases and promoters of human health. The final two chapters highlight the psycho-social and psychophysiological aspects of human-animal interactions. The book offers an integrated approach to the One Health concept, providing, in a truly holistic manner, tools to assess the equilibrium between   the environment, menand animals. This exercise will highlight and reshape our position towards the planet that despite being “a microscopic dot   on a microscopic dot lost in the unimaginable infinity of the Universe” is still our own. At the end of the day, pets will always be there to help us.
