Janna returned home from school to find a terrible mess. "There was birdseed everywhere, and it was just awful," the teen told InsideEdition.com. There was only one suspect: Molly, the family's 7-year-old Bernese Mountain Dog. Janna tried to confront Molly about the crime, but "in her puppylike way, she just turned around when I tried to scold her." It added insult to injury. "Molly didn't even offer to help clean up," Janna said.
