The homeowner and father are due in court Wednesday in Fond du Lac County.
Sheriff's Lt. Cameron McGee says the alleged incident happened Friday in the Town of Osceola.
Authorities say the homeowner had the dog attack once as a means of interrogation. The teen was then allegedly bound and hung upside-down from porch rafters while the dog attacked again. McGee says the teen's father may have participated.
The teen was treated for dog bites all over his body.
The Fond du Lac Reporter says another person arrived at the home and called 911.
