At the Human-Animal Alliance, we fund organizations using the human-animal bond to help people heal because this work is about more than a heartwarming connection.
There is science behind it.
Research has found that positive interactions with animals can affect both physical and emotional well-being. Studies have shown that interacting with animals can increase oxytocin, a hormone associated with bonding and connection, while reducing cortisol, a hormone involved in the body’s stress response.
The CDC notes that having pets has been associated with decreased blood pressure, cholesterol and triglyceride levels, as well as reduced feelings of loneliness. The American Heart Association has also reported evidence suggesting pet ownership may be associated with decreased cardiovascular risk and can help moderate the body’s response to stress.
The Human-Animal Bond Lab at the University of Arizona College of Veterinary Medicine continues to study how positive interactions with animals may provide therapeutic benefits, including among vulnerable populations.
This science helps explain what the organizations we fund see in practice: animals can create opportunities for connection, trust, emotional regulation and confidence.
That is why we invest in responsible, purposeful animal-assisted programs serving people in need.
The human-animal bond isn’t simply something we believe in. It is something researchers continue to study—and our grantees put into practice every day.
The Human-Animal Alliance (H-AA) is a nonprofit organization that deeply believes in the power and value of human-animal connection. Founded in 2022 by advocate and philanthropist Jackie Ducci, H-AA awards grants to charitable initiatives nationwide that recognize animals as essential partners in healing, connection, and purpose. Overhead expenses are privately funded, ensuring that one hundred percent of every donation directly supports impactful work.
