Oren Abeles, an English department graduate assistant at the University of North Carolina, Chapel Hill, brought his dog, Ginger, and his roommate's dog, Molly to his class, Mar. 22, 2013. Abeles said the students enjoy the dogs in the class that can be stressful at times. "My mind is always thinking even when it doesn't look like I'm thinking," Abeles said. "There is never a dull moment in my mind."
