muffysb, thanks for the comments.
You're right on all your comments. The animation composition was done like this:
1) Create a simple dog head turn.
2) The head turn is due to something calling the attention from the left side of the dog (and that's why it moved the tail)
3) I modified the eyes direction and added the ball passing.
So you're right, the dog's behavior is not consistent with the ball passing

I was just animating "on the fly" nothing on mind to communicate.
