Jack the Bulldog
Jack the Bulldog is the official mascot of the Georgetown University Hoyas athletic teams. Jack has been the name of at least five live Bulldogs since 1962, when the name first came into use, though Georgetown counts seven official bulldog mascots including the two living ones. The current incarnation of Jack is an English Bulldog born in 2013 whose full name is John B. Carroll.
Arkansas Razorbacks
The Arkansas Razorbacks, also known as the Hogs, are the mascots of college sports teams at the University of Arkansas in Fayetteville, Arkansas. The University of Arkansas student body voted to change the name of the school mascot (originally the Cardinals) in 1910 to the Arkansas Razorbacks after a hard fought battle against LSU in which they were said to play like a "wild band of Razorback hogs" by former coach Hugo Bezdek. The Arkansas Razorbacks are the only major sports team in the US with a porcine nickname, though the Texas A&M–Kingsville Javelinas play in Division II.
