A runaway dog spent two days in a dark Caltrain tunnel in San Francisco before he was rescued, San Francisco Animal Care and Control said Tuesday.
The dog, “Roo,” was recently adopted, but an incident where he got spooked prompted him to run off, according to Animal Care & Control San Francisco.


A train operator saw him on the first day, but they thought he was a dead animal, officials said.
Another train operator was going through the tunnel on the second day and saw the dog move, officials said.
“He was so still they thought he had been hit by a train and was injured,” animal control officials said.


The alarming observation triggered an immediate response.
This prompted two officers to go into the dark tunnel, where moments later they encountered Roo, officials said.
What they found was far different from what train operators feared.
“He was terrified at first, then was thrilled to be rescued,” officials said, adding that he was not injured.


The rescue revealed a piece of good fortune: Roo had been microchipped.
Roo was microchipped and safely reunited with his owner, who had been looking for him.
It turned out Roo had a loving waiting for his return.
The dog’s name is Roo, and he is a foster dog who was returned to his home in Humboldt County, where he was thrilled to be reunited with his foster family.

The harrowing ordeal highlighted how crucial microchipping can be in reuniting lost pets with their families. Animal Care and Control officers emphasized the importance of identification, noting that without the microchip, Roo may never have found his way home.
The dark tunnel where Roo had huddled in fear for two days stood as a stark reminder of how quickly a spooked dog can disappear into unfamiliar territory. Yet his survival and swift return showed the power of technology and the dedication of rescue personnel working together.
A missing dog has been reunited with its owner after spending two days “scared and hunkered down” inside a Caltrain tunnel in San Francisco, animal control officials said.
In the viral moment that unfolded over Tuesday and Wednesday, Roo became a symbol of hope.
