YOUR DONATION TO THE HUMANE SOCIETY OF SOUTHERN ARIZONA MAKES OUR COMMUNITY A BETTER PLACE. Your gift helps us meet the increasing demand for our services, including our low-cost and free veterinary clinic services (like spay/neuter, wellness, vaccinations, and dental cleanings) 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.
