Because San Mateo County stretches from the Pacific Coast across the Peninsula to the San Francisco Bay, pets are sometimes found, reported, or transported beyond the community where they originally went missing. Expanding your search beyond your immediate neighborhood and utilizing multiple reporting resources—including local shelters, animal control agencies, lost-and-found pet groups, and broader Bay Area resources—can significantly improve the chances of a successful reunion.

San Mateo County Lost Pet Resources

Losing a pet can be overwhelming, and knowing where to start isn't always easy. San Mateo County covers a diverse geographic area, from the coastal communities of Half Moon Bay and Pacifica to the Peninsula cities of Daly City, South San Francisco, San Bruno, Burlingame, San Mateo, Foster City, Belmont, San Carlos, Redwood City, and Menlo Park. A pet that goes missing in one community may be reported, found, or taken to a shelter in another, making it important to cast a wide net during your recovery efforts.

One of the biggest mistakes pet owners make is relying on a single resource. Successful recoveries often happen because information is shared in multiple places. A lost dog may be reported to animal control, posted in several Facebook groups, spotted by a community member, and eventually taken to a local shelter. The more places your pet is reported, the greater the chance that the right person will see the information and help bring them home.

This directory was created to make that process easier. It brings together San Mateo County animal shelters, animal control agencies, lost-and-found pet groups, rescue organizations, and other helpful resources in one convenient location. Whether you are searching for a missing pet or trying to reunite a found pet with its owner, these organizations and online communities can play an important role in a successful recovery.

Because San Mateo County is part of the larger San Francisco Bay Area and shares borders with San Francisco and Santa Clara counties, pets are sometimes found, reported, or transported beyond the community where they originally went missing. A pet lost in Redwood City may be reported in Palo Alto, while a pet found in Daly City may be taken to a shelter serving another part of the Bay Area. Expanding your search beyond your immediate neighborhood and utilizing regional resources can significantly increase the number of people who see your pet's information.

We encourage pet owners to use multiple resources, remain persistent, and continue checking back regularly. New animals arrive at shelters every day, new sightings are reported, and online posts are constantly being shared. Many pets are reunited after days, weeks, or even months because their owners continued looking and kept their information visible.

Our goal is simple: help you quickly find the people, organizations, and communities most likely to assist in bringing your pet home.

Frequently Asked Questions

Where should I report a lost dog in San Mateo County?

Report your lost dog in as many appropriate places as possible. Start by contacting local animal control agencies and shelters serving Solano County, then post in local lost-and-found pet groups and community pages. A pet found in one city may be reported or taken to a shelter in another, so expanding your outreach beyond your immediate neighborhood can significantly improve your chances of a reunion.

How often should I check shelters?

Check shelters frequently, ideally every day. New animals arrive daily, and intake photos or descriptions may not always perfectly match your pet. If possible, visit shelters in person in addition to checking their websites and social media pages. Persistence is often a key factor in successful reunions.

Do shelters hold animals for a certain number of days?

Holding periods vary by agency and can depend on factors such as identification, health, and available shelter space. Contact each shelter directly for their current policies and continue checking back regularly. Even if your pet is not present during your first visit, they may arrive later.

What should I do if I find a pet?

If you find a dog or cat, first check for identification tags and contact the owner if possible. Have the pet scanned for a microchip at a veterinary clinic, shelter, or animal control agency. Report the found pet to local shelters and animal control, and post clear photos and information in local lost-and-found pet groups. Taking these steps helps reunite pets with their families as quickly as possible.

What if my pet has a microchip?

A microchip can be one of the most effective tools for recovering a lost pet—but only if the registration information is current. If your pet is missing, log in to your microchip registry and verify that your phone number, address, and emergency contacts are correct. If someone finds your pet and has them scanned, accurate information can help reunite you quickly.
