I have experienced this in my Realm, as has my wife. If a wolf gets wet from rain or a water block it will make the sound for shaking off water in a loop. The sound doesn't stop even in broad daylight unless you avoid that wolf or kill it. Even if it is turned to your dog it continues to make the noise. We killed off our wolves because the noise was so loud we couldn't hear anything else in the game.
