Tamed Wolves Appear Hurt on Login

Upon player login, all of that player's tamed wolves appear to be near-dead. Tails are down all the way and they wimper as if hurt. If fed, tamed wolves stay healthy for the duration the player is logged in and if the tamed wolf hasn't taken damage. Upon relogging in, the tamed wolves revert back to their 'hurt mode'.

This affects both single and multiplayer.
