All dogs must be vaccinated against rabies and licensed by the age of 4 months or within 60 days of acquiring the animal.
All cats residing in the cities of Belmont, Brisbane, Hillsborough, Millbrae, Redwood City and San Mateo City and all unincorporated areas of the county must be vaccinated against rabies and licensed by the age of 4 months or within 60 days of acquiring the animal. Cats residing in East Palo Alto and Half Moon Bay must have a current vaccine. Cats in all other areas of the County are not required to be licensed at this time, however, it is a highly recommended form of identification for both dogs and cats.
Your license is due on the first of the month in which your license expires. There is a grace period of 30 days in which to make payment for your pet’s license.
By ordinance, a late fee is added if payment is not made within 30 days of the due date.
A license year begins the month your pet is vaccinated for rabies and ends the same month of the next calendar year or the month a new rabies vaccination is given, whichever comes first. For example, if a rabies shot is given in the month of April, the license year would be from April to April. But if a new rabies vaccination is given in March, the license would expire in March. A license may not always be a 12 month period. It is easiest and most cost-effective to vaccinate and license your animal during the same month each time the rabies vaccine and license are due.
If your pet receives a three-year rabies vaccination, a three-year license may be purchased. Please note that by state law, a license may not be valid beyond the expiration of the rabies vaccination.
