The 9-week-old English bulldog set to become the new mascot for the U.S. Marine Corps has arrived at the Marine Barracks in Washington.

Chesty arrived in the nation's capital Thursday, at which point the young pup was unveiled to the world.

Chesty is set to become Pfc. Chesty XIV on March 29, replacing Sgt. Chesty XIII. Until then, young Chesty will undergo obedience training.

After his arrival in Washington, Chesty met Bonnie Amos, wife of Gen. James F. Amos, commandant of the Marine Corps, according to the U.S. Marines. The pup is in the care of Staff Sgt. Jason Mosser, a member of the U.S. Marine Drum & Bugle Corps, and his wife Christine.

As the Marines' official mascot, Chesty's responsibilities will include marching in the Friday Evening Parades, as well as supporting events around the nation's capital.

Chesty comes from five generations of championship bulldogs, which are bred by mother-daughter team Sara Gomez and Abigail Callahan of Stephens City, Va., according to the Marines.

Marine mascots are named for the late Lt. Gen. Lewis "Chesty" Puller, one of the most decorated officers in the history of the Marine Corps.
