Ever since his official Changing of the Collar on February 29, 2020, Butler Blue IV has served proudly as the official mascot of Butler University. Blue has been part of the Butler community from the start -- his breeders, handler, and veterinarian are all Butler alums. This original illustration captures Blue in his element, ready to root on the Bulldogs at Hinkle Fieldhouse with a basketball in paw. Products are mocked up on a size S. Graphics may appear smaller on larger sizes.
