Marine Sergeant Ross Gundlach and bomb-sniffing dog Casey served in Afghanistan in 2011 and 2012, completing over 150 missions together, but then they were separated. They both came back to the United States eventually, but Gundlach returned to his hometown of Madison, Wisc. to go to college and Casey began working in Iowa as an explosives detection dog.
While they were in Afghanistan, Gundlach promised himself and Casey that if they made it out alive, he would do whatever it took to find her. Once he learned that she was working in the Iowa state fire marshal’s office, he wrote to the director, Ray Reynolds. Gundlach explained that he had a strong connection with Casey and that he loved her. Over a couple of months, he worked on convincing Reynolds to let him have Casey. Gundlach was told that if it worked out, he would have to drive to Iowa to get her, to which he replied, “I would swim to Japan for my dog.”
Reynolds invited Gundlach to Des Moines, Iowa, supposedly to plead his case to a committee at the state capitol, but Reynolds had actually already arranged for Gundlach to take Casey home with him. When Gundlach arrived, he was told that the meeting had been postponed, but invited him to participate in an Armed Services Day celebration. At that event, Reynolds surprised Gundlach by bringing Casey to him and letting him know that the dog was now his. 
This happy reunion was made possible because Reynolds and his colleagues understand the importance of the relationship between a Marine and his partner, a detection dog who saved many lives with her flawless work. It was also enabled by a donation of $8500 by the Iowa Elk’s Association to purchase another working dog for the agency. Casey was officially retired from active duty by Iowa Governor Terry Branstad at the ceremony in which Gundlach and Casey were reunited.
Gundlach has a tattoo of Casey with angel wings and a halo sitting by a Marine, and he gives her credit for his survival in Afghanistan. It seems only fitting that the two of them are together again.
