High Quality Content by WIKIPEDIA articles! Jack the Bulldog is the official mascot of the Georgetown University Hoyas athletics teams. Jack has been the name of at least four live Bulldogs since 1962, when the name first came into use. The current incarnation of Jack is an English Bulldog born in 2003 whose full name is John S. Carroll. Jack is also portrayed by a costumed character Bulldog mascot, a tradition dating to 1977. Jack was not always the name of the Georgetown Hoyas` mascot, nor was the mascot always a bulldog, as other types of dogs, particularly bull terriers, were associated with the sports teams before 1962. Today, Georgetown is among thirty-nine American universities to use a bulldog as their mascot.
