Hundreds of people in Michigan came together to say a tear-filled final goodbye to a cancer-stricken dog who served three tours in Afghanistan with the U.S. Marines.

Cena the 10-year-old black lab received a hero’s farewell Wednesday before being euthanized at the USS LST 393, a museum ship in Muskegon, and carried off in a flag-draped coffin.

The celebration for Cena was organized by his owner, Lance Cpl. Jeff Young, who was paired with the dog in 2009 and 2010 while on a combat tour in Afghanistan and who adopted him in 2014.
