YOUR DONATION TO THE HUMANE SOCIETY OF SOUTHERN ARIZONA MAKES OUR COMMUNITY A BETTER PLACE. Your gift helps us meet the increased demand for our services to low-income families, including our low-cost and free clinic services (like spay/neuter, wellness, vaccinations, dog dental) and our monthly free pet food distribution programs to help families keep their pets in their loving forever homes. Your donation supports every one of the 5,000+ pets that will come through our doors this coming year.
