Free services (surgery and a rabies vaccination) are provided on our satellite clinics for animals living in qualifying low-income households. Those who do not qualify for our free programs are welcome to use our reduced-cost stationary clinics. Special funding from generous donors sometimes enables us to hold spay-neuter events that are free for all animals. View our satellite clinics page to find out whether any such events are currently scheduled. We currently operate within the state of Texas with periodic trips to other U.S. states and international locations. Please see individual clinic webpages for full information about how each clinic operates and how to get your animal(s) spayed or neutered.
