Wolves are missing some idle sounds

Wolves are still missing these idle sounds. (still affects 1.2.x)

When your pet tamed wolf is sitting when left alone for a while

• wolf wine

There is another sound but it's not to my knowledge if it was ever heard in the game. Therefore I cannot confirm if this sound is in the game or not.

• wolf howl
