The team started play in 1999 as the
Mankato Mashers, effectively serving as a replacement for the
Kenosha Kroakers club which had folded after the 1998 season. In their inaugural season, the Mashers were the only team in the Northwoods League to broadcast their games on television. The Mashers were renamed in 2002 to the MoonDogs when the franchise was acquired by Joe Schwei. The Moondogs were again sold in January 2013 to Mark Ogren. The current ownership group of Chad Superenant and Kyle Smith took over the club in 2018. From 2008 to 2018 the MoonDogs made the playoffs eight of eleven season, making it to the NWL Summer Collegiate World Series on three occasions. In 2014 the MoonDogs were defeated by the
Lakeshore Chinooks in a two-game series sweep. == Season-by-season ==
