Wild and tamed wolves have begun glitching by looping the beginning of their shaking animation, where they would shake off water from their fur. It would also create the looped sounds of the ruffling and splashing, sounding like rattling, and the models' heads would twitch as they tried to shake the water off. They wouldn't be able to move, and only stare at the player if they came too close.
