The United States Marine Corps adopted the bulldog as its unofficial mascot at the end of World War I. Generally, the bulldog is recognized as a loyal, courageous, and tough breed. Chesty—the Marine Corps bulldog—is symbolic of these traits and all those that capture the spirit of the "devil dog." Historically, "teufel hunden" or "devil dog" is the nickname that the Germans gave to the Marines that fought so fiercely in the battle of Belleau Wood in France during World War I. The nickname stuck and Chesty's legacy in the Marine Corps continues to this day.

Fun Facts

• The first of a long line of Chestys enlisted in 1957, named after the most decorated Marine in history—Lt. Gen. Lewis B. "Chesty" Puller.
• The current Chesty, Chesty XVI, reported for duty in early 2022. He is the 16th Chesty in line to serve. He is expected to retire at the end of Summer 2026. The incoming Chesty—Chesty XVII—was introduced at Marine Barracks Washington, D.C. in June 2026. 
• When training is complete, a newly enlisted Chesty reports to his home at Marine Barracks Washington D.C. where he, like his fellow Marines, performs official duties such as attending ceremonies and participating in parades with the Marine Corps Silent Drill Team.
• Chesty VI was demoted in 1979 for destroying government property among other offenses. He was reported for chewing up a punching bag, and received 14 days extra duty for biting the two corporals, according to the charge sheets.
