Spuds MacKenzie is a Bull Terrier dog character used for an extensive advertising campaign marketing Bud Light beer in the late 1980s. The Spuds MacKenzie mascot and campaign was the idea of a 23-year-old art director, Jon Moore. At the time, he was working at Needham, Harper, and Steers, a Chicago advertising agency. The dog first showed up in a Bud Light Super Bowl XXI advertisement in 1987.
