The reunion happened thanks to an anonymous tip called into Florida's Hillsborough County Sheriff's Office.
Spokesman Danny Alvarez said in a news release that Donald Murray's car was stolen on May 29, with no sign of Guido.
Murray's car was found abandoned behind a grocery store and an employee at a dry-cleaning business found Guido wandering around. Another employee, Karlene Rowell, took Guido home and cared for him.
When a tip came in, investigators took Murray to Rowell's house on Tuesday night. He confirmed the dog was Guido. Alvarez said Rowell and her family were sad to say goodbye, but happy Guido was reunited with Murray.
