Steven Rosales, the former school resource officer in Kewaskum, is facing allegations of bestiality.
Fond du Lac County prosecutors filed five felony counts related to bestiality against Rosales yesterday.
During an investigation into his inappropriate communication with a teenage girl from Kewaskum High School, evidence emerged suggesting he engaged in a sexual act with his dog.
Rosales is scheduled to appear in court today to address these charges.
Earlier this month, he lost his job and faced sex-related charges for an improper relationship with a student.
