Sans had communicated that he would be away for a while, so that the dogs wouldn't freak out too much. Dogs have never been very good at understanding that concept, though.

That changed a few hours ago. Since then, all they've been doing is tearing up the treeline of that carnival, howling and baying for attention, as they searched to find out here their master had gone. When people start returning it only becomes more frantic. Others are here, but Sans isn't here.
