Sean told BuzzFeed News Willy is a 7-year-old miniature Shetland collie who he loves having around.
"He's a relaxed fun dog," Sean said.
Sean said he actually tried to bring Willy last semester as well, but his parents caught him when he was about to leave.
"After that I got the feeling from them it wasn't too big of a deal," he said.
