In a world where dogs act like humans, Otto is a short, chubby Boston Terrier who works as a professor at P.U.P. University. He enjoys teaching philosophy, and his classroom is generally upbeat and fun for students. In his free time, he spends time in the university library or his office at home reading books while drinking coffee, even though it gives him a tummy ache. He is cheerful, absentminded, and intelligent.
