What is the human-animal bond and why is it important to The Pet Care Trust? The human-animal bond is a unique, mutually beneficial relationship between people and animals; it has a major impact on the health and well-being of both. This includes, but is not limited to, emotional, psychological, and physical interactions of people, animals and the environment. By taking part in studies on the human-animal bond we are increasing our knowledge about this bond and by assessing how animals enrich our lives, we can improve the quality of life for both humans and animals.
