In early April, Cleveland Police picked up a large, yellowish stray dog. The kennel City Dogs Cleveland took the animal in and found a microchip during an exam. Workers there called the listed number but were in for almost as much of a surprise as the owner was. Michael Joy, who at one point was a recruiter for the U.S. Army, was the dog’s owner. The animal’s name was Sam, and he was very much loved — and missed. But he’d been missing for over four years.
