We're Your Pet Health Experts.
Spay Neuter Network (SNN) operates four spay/neuter clinics, a mobile spay-neuter program, and a transport program in partnership with over 16 counties to provide free and affordable spay/neuter and essential wellness services for financially challenged pet owners. SNN is nationally recognized for its high-quality, high-volume (HQHV) spay/neuter expertise. We provide free and affordable HQHV spay/neuter, wellness, and vaccination services for dogs and cats in neighborhoods with little to no access to basic veterinary care.
We keep our services low-cost and high-quality thanks to our nationally-recognized expertise in the procedure. Thanks to our dedicated staff, volunteers, and generous donors (like you), we’ve been able to help owners in Texas keep their pets healthy since 2004.

Spay Neuter Network’s mission is to eliminate pet overpopulation through spay/neuter, while empowering communities to care responsibly for dogs and cats.
Overpopulation places a strain on our shelters and communities. By offering free or low-cost spay/neuter, and by empowering our communities to care responsibly for their pets, we can be the pet health experts for animals and owners who need us the most.

How We Operate
Quality Clinics
We currently operate four high-volume, high-quality spay/neuter clinics: one in Crandall, Texas, just three miles east of Dallas County, the second in southern Dallas, the third in Ft. Worth, and a fourth in San Antonio. We also operate a fully functional Mobile Animal Surgery Hospital (MASH) that is capable of serving up to 50 pets a day in Ft. Worth and rural communities across North Texas. Additionally, we offer pet transport services to and from our stationary clinics with our Transport Vans. These allow us to assist pet owners in need of transportation options.
Approachable Education
Our Community Outreach Team knows that education is a crucial component in your animal's wellbeing. We know you want to do what's best for your pets, so our team goes door-to-door, speaks at schools and churches, and sets up booths at events to help provide information to owners like you about local laws and where available resources can be found. In 2018, we launched our SNN North Texas Education Initiative, where we partner with Ft. Worth ISD to educate children in low-income, high-risk areas about pet ownership, compassion, proper pet handling, pet safety, and more. We're dedicated to changing the culture in these communities to one that will decrease pet bites and roaming, and increase the quality of life for both pets and their owners.
Community Collaboration
While we're committed to solving our pet overpopulation problem, we know we can't do it alone. That's why we partner with more than 36 cities and rescue groups to tackle this issue, together. We also serve on teams working to develop powerful animal wellbeing plans and policies for cities, counties, and municipalities in Texas. Many of our staff volunteer to support rescue organizations and other groups, further helping animals in our communities.
Disaster Response
Our large MASH unit and highly-trained medical team make us uniquely qualified to respond to disasters that impact pets across Texas. We respond to emergencies to offer triage, treatment, and general support in times of crisis around the state, including the Canton tornado and Hurricane Harvey in 2017.
Pet Support
Award-winning partnership with the City of Dallas and Dallas Animal Services to provide resources to keep pets in their homes or provide foster care and adoption alternatives to the city animal shelter.
Community Resources
We serve a a resource for affordable and free options for pet food, medical care and more for families in need.
Our Founding
In 2003, Bonnie Hill embarked on a journey that reshaped the landscape of animal welfare in her rural county. Upon moving to a farmhouse outside Dallas, Bonnie and her husband were greeted by a litter of 10 puppies abandoned by the previous owners. With no animal shelters in their community to help, Bonnie pivoted to a solution-focused approach, centering on spaying and neutering. In 2004, she established Spay Neuter Network (SNN), and launched a mobile spay-neuter clinic serving about 2,000 dogs and cats in Kaufman County. Through her leadership and the unwavering support of her board members - Carol Shiels, Terri Maloney, Robert Green, and Richard Hill - Bonnie laid the foundation for a remarkable journey of compassion and impact. Today, Bonnie's legacy endures as SNN continues to expand its reach into all of Texas, providing essential services to more than 45,000 dogs and cats annually across Texas.
