The only dog I remember is the one who challenged Mushmouth Pacetti and lost based on a technicality in a pizza eating contest.
"Mushmouth" Mariano Pacetti officially won the contest by default.
His challenger on Cleveland’s famous
Hoolihan and Big Chuck show was a 65-pound German shepherd named
Chris "The Fairview Fireball". Chris easily out-ate the legendary champion, inhaling a fully loaded medium pizza in less than 30 seconds.
However, the judges consulted the official rulebook—specifically invoking a technicality that required all competitive eating contestants to be
human. Because of this rule, Chris was disqualified, and Pacetti retained his title as the reigning pizza-eating king.
