Spay/Neuter Appointments at the SAHS

Thank you for having your pet spayed/neutered at the San Antonio Humane Society (SAHS). This operation helps decrease the number of unwanted pets in our city as well as improves your pet’s chances for a longer, healthier life. We strongly recommend that you establish a relationship with a full-service veterinary clinic to ensure your pet gets continued care, including vaccine boosters, deworming, heartworm and flea/tick prevention, and all health issues NOT directly related to this surgery.

Spay and neuter services are available to the public by appointment only.

You can now schedule your pet's spay/neuter appointment online! Please follow the link below to schedule your pet’s appointment. Availability is based on staff levels as well as weight, species, and sex of the animal. Please enter all information as accurately as possible. If you can't find an available time, please check back as we will open future months once availability is determined. If you do not find a time that works for you and you’d like to be added to the waitlist, please submit this form to provide your availability. Please note that there might be a 30 minute to 1 hour wait when your pet is being checked in! Two locations, either our shelter on Fredericksburg Rd. or our Brooks Spay/Neuter Clinic on City Base Landing.

Payment is required to schedule an appointment. YOU COULD QUALIFY FOR A FREE SURGERY! Please review zip code grant availability, before making your appointment. The zip code grant must be used when scheduling your appointment.

For zip codes that qualify for FREE spay/neuter surgeries, please email (no phone calls) PRIOR to scheduling. A unique coupon code will be sent to those eligible pet owners which will exempt them from payment. This code should be used when scheduling the appointment. If a grant requires documentation for proof of zip code (eg, driver’s license or utility bill), please bring it with you when you drop off your pet in the morning. Missing documentation will result in payment required for services.

If you require assistance with scheduling, or if you do not have access to a computer, please call 210.424.7595.

If it says we don't have any appointments available the month you are looking for, it means we are either already fully booked, or haven't opened it up for scheduling yet.

Cancellation/Rescheduling Policy: If you cancel your appointment 48 hours in advance, a full refund will be returned to the original card used for payment. Appointments can be rescheduled up to 48 hours in advance w/ no additional fees.

Pets must be at least 8 weeks old and weigh at least 2 lbs. See Pre-Surgery Instructions.

A Rabies Certificate, which must include the animal’s name, description, date, and SIGNATURE of the veterinarian, must be presented at the time of drop off in the morning before surgery.

If you do not have proof of current rabies vaccine, we can administer the rabies vaccine at the time of surgery for an additional cost of $10.

Rabies (and proof of vaccination) is required by Texas state law for any animal 16 weeks of age and older, and can be administered as early as 12 weeks of age. More info about Rabies.

Additional services can be performed at the time of surgery for additional fees. See additional services.

Check in and drop off of your pet begins at 7:30 am on the day of your appointment. Payment is due when you drop off your pet. Your pet will be ready to go home starting at 4:30 pm. See Post-Operative Instructions.

Grants Available
The city of San Antonio and other charitable organizations do have grant sponsorships available to help assist with costs of surgery. Check our current available grants to see if you qualify. If a grant requires documentation for proof (eg, driver’s license or utility bill), we will not be able to honor the grant without documentation. Please be sure you bring it with you when you drop your pet off in the morning.

Current available grants (2):
- Zip Code (eligible zip codes for free spay/neuter for your dog or cat).
- FULLY BOOKED - Beat the Heat (March and April)

Feral Cats
Feral cats must be brought in an approved trap, and are limited to 10 surgeries per day on Mondays, Tuesdays, Thursdays, and Fridays. Check in for feral cats is at 7:15 am. All feral cats will receive a permanent green tattoo on their abdomen as well as an ear tip, to designate sterilized status. We cannot accept feral cats if they are not in an approved feral cat trap, as they are a danger to themselves and our staff. If you have not attended a feral cat trapping training class, please do not attempt to trap feral cats on your own or bring them in an inappropriate carrier. This only creates added stress to the cat, and we will not be able to perform surgery. See info about local feral cat groups/training classes.
