Jiggs II (September 22, 1925 – March 30, 1937), also known as Silent White Richard, was the second of a number of English Bulldogs to serve as mascots of the United States Marine Corps.

[3] At the time of his donation, Jiggs II was 17 months old, stood 15 inches (380 mm) high, and weighed 47 pounds (21 kg).

[2][3] Some months after Tunney donated Jiggs II, the dog was temporarily transferred back to the boxer to serve as mascot at his Chicago training camp before being returned to Marine service.

[3] Early in his military career, the Boston Globe described Jiggs II as "ferocious looking" but with a "mild manner and gentle disposition".

[2] Writing in a 1937 issue of American Kennel Gazette, then retired Sergeant Major Clarance Proctor affirmed this description of Jiggs II.
