Without his uniform on, Fred Elwell's dog, Kaiser, might look like an ordinary German shepherd. But don't be fooled; Kaiser is a search-and-rescue machine and after three years of training, he's ready to chip in and help out area fire and police departments. Elwell, a Newburyport firefighter, adopted Kaiser as an 8-week-old puppy while he was out of work because of an injury. The pair soon became inseparable, and when Elwell returned to his job at the Newburyport Fire Department, he knew it was time for Kaiser to find work as well. On his first birthday, Kaiser started training to receive his wilderness search certification from the International Police Work Dog Association and began a series of tests and drills that would soon make him able to find a missing person in a 40-acre wilderness.
