Overview
- Caltrain staff first spotted a medium-sized brown and white dog curled against a tunnel wall in Potrero Hill and later saw him move, prompting a rescue response.
- San Francisco Animal Care and Control officers entered the dark tunnel and led the frightened dog out on a leash while the agency posted video documenting the retrieval.
- The dog, Roo, had been recently adopted and bolted from his new owner, and officers used his microchip to confirm identity and complete the reunification.
- A local veterinarian examined Roo and reported he was “a little wobbly” after the rescue but otherwise in good health.
- Caltrain called the outcome highly unusual and the case highlights how microchipping and quick interagency coordination can speed safe returns of lost pets in urban transit areas.
