Wolf Update

I think wolf is really old mob and doesn't update that much since 1.9 which looks like it's out dated, I think it should have more animations like when you sleep, it sleep along with you like a cat, or when it has low health, it looks exhausted and also I don't think it's make sense that the dog can eat raw chicken and rotten flesh since it can make player got bad effect but wolf doesn't. Sometime wolf looks all the same (except the color on its neck) it should have more different color like gray/white, black/white, black/gray. To make it different. And sometime thinking of it behavior. Many player has this problem, wolf doesn't care if creepers gonna explode and just ran into it and died. So it would be better if it just ran out of the place to make them safe (more make sense since no one gonna go hug creeper).
