Spay & Neuter

Spay & Neuter Appointments

In general, appointments for spay & neuter surgeries open on the fourth Monday of each month for the following month. If the appointment type you need is not available, please check back at a later date. There is a high demand for appointments and we appreciate your patience while we care for pets in our community.

If you need to schedule a spay or neuter surgery quickly, you may want to consider contacting your regular veterinarian. We encourage you to check back periodically for available appointments, or you can review this list of other clinics that offer spay & neuter services.

If you think your pet is having a medical emergency, take them to a veterinary hospital right away.
