Requests for exemptions for rabies vaccinations should follow the format described on the San Mateo County Animal Licensing website.
In brief, two forms must be completed by the veterinarian. Information includes the pet’s microchip number, recent physical examination date, and the medical condition for which rabies vaccination exemption is requested. Medical records that support the request must be included with the forms. The owner signs one of these forms, acknowledging liability and understanding that, if approved, the exemption will be valid for one year.
An FAQ file is available on the San Mateo County Animal Services website to answer your questions about this process.
