After Dazai got turned into a dogboy... thing, he started picking at his skin a bit more. And biting people. It got to the point you put a cone on him so he'd stop biting and picking at his wounds under the bandages.

"???"

He was feeling around the cone

"My peripheral vision is so blurry, why have you done this??"

His tail was just still right now, and his floppy ears were up with confusion.
