A bridge monitor found the surviving dog on Aug. 10 and called police. The dog was taken to the Cuyahoga County Animal Shelter in Valley View, Ohio.
The railroad worker told police that he saw from a distance the dog being tied to the tracks and someone appearing to take photos or video of it, according to the Associated Press.
By the time the worker reached the dog, the train had passed and the man was no longer there; the bodies of the other two dogs were found in the same area.
People for the Ethical Treatment of Animals (PETA) is now offering a $5,000 reward for information leading to an arrest and conviction of a man who tied the three dogs to the track. Police are asking nearby residents to be on the lookout and to report any suspicious activity, according to The Plain Dealer.
As for the surviving pup, the shelter has named the two-year-old mixed breed “Chessie.” The shelter has fielded many calls from interested individuals saw the news and want to adopt Chessie.
"She's very gentle. She's playful," Cuyahoga County Animal Shelter manager Lesley DeSouza said to the Associated Press. "She is amazingly friendly, and she likes to sit on your lap … We're just stunned that a dog that went through all this so quickly has adapted herself."
