Humane Society of Southern Arizona: A No-Kill Shelter Serving Tucson Since 1944

Share this online:

Arizona’s Oldest and Largest No-Kill Animal Welfare Organization

The Humane Society of Southern Arizona (HSSA) has served the Tucson community for over 80 years. Established in 1944, this independent nonprofit is dedicated to improving the lives of homeless and at-risk animals through shelter, adoption, medical care, and education. Located at 635 W Roger Road in Northwest Tucson, HSSA operates as a no-kill facility and helps more than 13,000 animals each year find safety, care, and new homes.

HSSA is more than an adoption center. It offers low-cost veterinary services, supports responsible pet ownership, and runs educational programs for all ages. Whether you’re looking to adopt, volunteer, or find affordable pet care, HSSA is a trusted resource with a long-standing commitment to animal welfare.

What Services Does HSSA Provide?

As a full-service animal welfare organization, the Humane Society of Southern Arizona offers a wide range of programs and services designed to support pets and their people:

Adoptions: Dogs, cats, puppies, kittens, and small animals are available for adoption with behavior and medical evaluations provided before placement.
Low-Cost Spay & Neuter: Affordable surgical services help reduce pet overpopulation and prevent unwanted litters.
Vaccination & Microchipping: Routine vaccines and microchip identification are available at reasonable rates to keep pets healthy and safe.
Education & Outreach: HSSA offers youth camps, school visits, and adult education programs focused on humane treatment and responsible pet care.
Lost & Found Services: Assistance with reuniting lost pets with their families through online listings and shelter intake.

Adopting a Pet from HSSA

HSSA’s adoption process is designed to create long-lasting matches between pets and families. Each adoptable animal is vaccinated, spayed or neutered, microchipped, and behavior-assessed prior to placement. The adoption staff works closely with visitors to help them find a companion that fits their lifestyle and household.

The adoption center includes dedicated areas for different species and sizes, as well as quiet meeting spaces where potential adopters can spend time with animals before making a decision. Seniors, veterans, and those adopting multiple animals may qualify for adoption fee discounts.

A Lifesaving Mission in Action

As a no-kill shelter, HSSA is committed to ensuring that every healthy and treatable animal in its care has the opportunity to be adopted. This is achieved through careful intake management, strong foster and volunteer networks, and medical support for animals with treatable conditions.

Many families turn to HSSA after losing a pet, seeing adoption as a meaningful way to honor a companion’s memory. If you’re navigating a difficult goodbye, you may want to review this guide on feline kidney disease and quality of life for thoughtful advice on making compassionate decisions.

Veterinary Support and Community Care

In addition to adoptions, HSSA provides preventive veterinary care at affordable prices. Their Spay & Neuter Clinic and Vaccination Clinics help reduce barriers to basic pet health services, especially for low-income households. By offering these options, HSSA works to keep pets healthy, in homes, and out of shelters.

Services are available by appointment, with some walk-in hours for vaccines and microchipping. Seasonal events such as free rabies vaccine days and adoption drives help broaden access even further.

Education and Volunteer Opportunities

HSSA invests in the next generation of animal advocates through its Humane Education program. Youth summer camps, reading programs, and classroom visits help children build empathy and learn about responsible pet ownership. Adult volunteers also play a critical role at the shelter, assisting with animal care, adoptions, and outreach events.

For those unable to adopt, volunteering or fostering is a powerful way to make a difference in the lives of shelter animals. HSSA provides training and flexible schedules for individuals and families ready to help.

"I can’t begin to say enough nice things about Dr. Miller, her demeanor and her professionalism. My beloved cat Van was in the final stages of debilitating malignant thyroid tumors that left him unable to eat and drink in his final days. Dr. Miller’s service of coming to the house to help Van peacefully pass was a relief. Dr. Miller’s comforting actions with Van and her reassurances to me helped make what was already a horrific experience as bearable as possible under the circumstances."
