Ball crazy

The one thing I wish she wasn't and that is ball crazy.  She forgets all manners when there is a ball around and becomes this frenzied rude, snappy and pushy dog.  If there was a survivor which tested dogs and their loves of balls, she would be a sure contender for the prize.  Hey ho.   I am not sure what training I can do to make her more respectful around people who have a ball in their hand.   It's a work in progress for sure.
