Steps to Finding a Lost Pet

Have you found a pet?

Animals found in the city of Sunnyvale:

HSSV houses stray animals from the city of Sunnyvale brought in by Sunnyvale residents. If you have found a Sunnyvale stray animal between the hours of 9 a.m. – 6 p.m. , and are a Sunnyvale resident (with valid ID), please bring it to our Sparkle Wilsey Pet Services Lobby.

If you have found a Sunnyvale stray animal outside of these hours, or do not have a valid ID, please do not come to HSSV. Instead, call Sunnyvale Dispatch at 408-730-7180 for an officer to transport to HSSV directly.

Animals found in cities other than Sunnyvale:

  • If the animal has a collar, start by calling/texting the number on the tag
  • Bring the animal to a veterinarian or your local shelter to scan for a microchip
  • If you found a dog, walk the dog in the neighborhood it was found and ask neighbors for help. This is also a great time to post “found pet” posters
  • Visit local animal shelters and fill out a found pet report
  • If you found the animal in the city of Sunnyvale, you may also report the animal to the city of Sunnyvale Animal Control Unit at 408-730-7178.
  • Take a good, clear photo of the pet and post to Finding Rover, NextDoor, and other lost and found online pet groups
