Spaying/neutering of all pets is encouraged at an early age for the better health of the pet. Animal Care Services (ACS) partners with the clinics listed below for free and low-cost spay/neuter.

We also urge all pet owners to establish a relationship with a veterinarian to protect the health of their pet.

The following zip codes are eligible for free spay/neuter services. If you live outside city limits or in a zip code that is not listed, you can still contact our partner clinics for low-cost services. (For the list of partner clinics, click here and scroll down to Find a Clinic.)

Eligible Zip Codes
You must be a resident of the City of San Antonio, living in one of the following zip codes: 78201, 78202, 78203, 78204, 78207, 78208, 78210, 78211, 78213, 78214, 78218, 78219, 78220, 78221, 78222, 78223, 78224, 78225, 78226, 78227, 78228, 78229, 78235, 78237, 78238, 78242

Proof of Residency
Most clinics in the city will need you to show them an ID or a bill with your address. Before you take your pet to the clinic, check with them about what you need to prove where you live.

Animal Age, Weight, and Health
Each clinic has its own rules and requirements. Usually, dogs and cats need to be at least two months old and weigh at least two pounds. The clinics will also check if your pet is healthy enough for the surgery. If you have questions, always ask the clinic's vet for help.

If you live in an eligible zip code, it is free to have your animal spayed/neutered. You will not need a special voucher to receive this service. If you live in a different area, ask your chosen clinic about appointments and fees.

The ACS-sponsored spay/neuter program is for pet sterilization only. Clinics may add extra fees for pets who need extra medical care or a rabies shot. Before you take your pet to the appointment, ask the clinic about any extra charges.
