Benny, the service dog missing from Upton, Massachusetts, has been found, police said early Saturday morning.
The 8-month-old yellow lab, which had been lost since Friday when he was spooked by a train whistle, is with his owner, police said in a press release.
Benny helps his owner, Bella Picard, recover from a spinal cord injury she suffered last year, and he is also one of her best friends, she said.
"He's the friendliest, goofiest - he literally reminds me of myself in a dog version," she said. "He's been, like, amazing."
Bella and Benny were in Bella's car when Benny was spooked by a train.
"He jumped up," she said. "I had the window cracked a little bit. Somehow put his paws on the thing to try to get out and rolled down the window himself."
Many town residents, including local police, helped in the search. Picard's story of recovery is well known in town, and many wanted to help.
