If your dog has gone missing in Pasadena or the surrounding communities—Arcadia, Bradbury, Glendale, La Cañada Flintridge, Monrovia, San Marino, Sierra Madre, or South Pasadena—the Pasadena Humane Society & SPCA should be your first stop. The moment you realize your dog is missing, head there to file a lost pet report with their team. They take lost dog cases seriously and have a systematic approach to helping reunite dogs with their owners.

When you arrive, you can check the kennels directly to see if your dog has been brought in by someone who found them. The staff will also help you review records of animals that have come through the facility, which is especially useful if your dog was picked up by animal control or a Good Samaritan. This hands-on searching beats just calling and hoping—you get to see the dogs yourself and get a sense of the operation.

Beyond the immediate search, their team can advise you on next steps, whether that’s posting lost dog alerts in the community, contacting local vets and shelters in adjacent areas, or working with their network of animal welfare partners. They understand the urgency and worry when a dog goes missing, and they have experience with the specifics of recovery in this region.

The Pasadena Humane Society also handles rescue and shelter operations, so if you’re looking to adopt, they have dogs available too. Either way, their staff can point you toward additional resources and support. The facility has been part of the Pasadena community for a long time and maintains strong connections with local animal control and rescue organizations throughout the San Gabriel Valley area.
