“His baby brother had been wild as a winter storm since he learned Robb was riding off to war, weeping and angry by turns. He'd refused to eat, cried and screamed for most of a night, even punched Old Nan when she tried to sing him to sleep, and then next day he'd vanished. Robb had set half the castle searching for him, and when at last they'd found him down in the crypts, Rickon had slashed at them with a rusted iron sword he'd snatched from a dead king's hand, and Shaggydog had come slavering out of the darkness like a green-eyed demon. The wolf was near as wild as Rickon; he'd bitten Gage on the arm and torn a chunk of flesh from Mikken's thigh. It had taken Robb himself and Grey Wind to bring him to bay.”
—Bran observes the rage of Rickon Stark and his dire wolf Shaggy Dog, A Game of Thrones, George R.R. Martin
