If your dog slipped the gate or your cat bolted out an open door, take a breath — you are not alone, and you can act right now. San Diego consistently ranks among the top U.S. cities for lost-pet reports in our nationwide data, which means our shelters, rescues, and neighbors are more experienced at pet reunions than almost anywhere else. This guide walks you through exactly what to do in the first hours, who to contact locally, and how to get the word out fast so your pet can find their way home.
Your first hours: a quick action plan
Most pets are found close to home and within the first day or two. Move quickly and calmly through these steps:
- Search your immediate area first. Walk the block calling your pet’s name in a normal, upbeat voice. Bring treats, a favorite squeaky toy, and a leash or carrier. Frightened cats often hide within a few houses of home.
- Check your microchip registration. Confirm your contact info is current with your chip provider so any shelter or vet that scans your pet can reach you instantly.
- File a lost report with the shelter of jurisdiction (details below) and search their found-pet listings in person and online.
- Post to online lost-pet networks. List your pet on Petco Love Lost, a free national database with facial-recognition matching, plus local neighborhood and social media groups.
- Make and post flyers. A clear photo, your pet’s name, the area last seen, and a phone number — posted at intersections, parks, and vet offices — still bring in real sightings.
San Diego shelters & animal services
Since July 2018, the San Diego Humane Society provides animal services and sheltering for the City of San Diego and many surrounding communities, replacing the county’s former role citywide. Its campuses cover different areas — the San Diego Campus at 5500 Gaines St. serves Central and South San Diego, with additional campuses in El Cajon, Escondido, and Oceanside handling nearby cities.
To report a found or lost pet, or to describe a pet you’ve lost, you can call the San Diego Humane Society at 619-299-7012. Search their online listing of stray pets in care, but also visit the shelter in person every day or two if you can. Staff and volunteers see dozens of animals, and only you will reliably recognize your own pet — descriptions and photos don’t always match.
If your pet went missing in an unincorporated part of the county rather than within a served city, the County of San Diego Department of Animal Services handles those areas — check their lost-and-found resources too. One important note: stray pets without traceable identification are typically held for just 72 hours, while pets with a microchip or ID tag are held for five days. That short window is why filing reports and visiting shelters quickly matters so much.
Reach every nearby shelter and neighbor at once
Calling shelters one at a time and hanging flyers is important — but it’s slow, and the clock is working against you. MyLostPetAlert.com was built to blast your pet’s photo and details across your whole neighborhood in minutes. We fax your lost-pet flyer to nearby shelters, veterinary offices, and rescues, send automated phone calls to your neighbors, run targeted Facebook ads in your search radius, and generate a printable flyer you can post the same day.
It’s a one-time fee — no subscription — and you get a verifiable delivery log showing exactly which shelters and numbers were reached, so you’re never guessing. There’s also a free tier to help you start right away. When every hour counts, doing all of this at once can make the difference.

Frequently asked questions
How long does San Diego Humane Society hold a stray pet?

My pet went missing in the City of San Diego — which shelter do I contact?
The San Diego Humane Society handles animal services for the City of San Diego. Call 619-299-7012 to report your lost pet and search their stray listings. If you lost your pet in an unincorporated county area, contact the County of San Diego Department of Animal Services instead.
What’s the fastest way to notify a lot of shelters and neighbors at once?
Contacting each shelter and vet individually takes time you may not have. A service like MyLostPetAlert.com faxes your flyer to nearby shelters and vets, phones neighbors, runs Facebook ads, and gives you a printable flyer — all from one report, with a delivery log confirming who was reached.
