To add to what Lies said :
Stay under threshold. That may mean that you don't leave your front yard for a couple weeks. Add distraction slowly and be prepared to take a step back. Move from the front yard to the street right in front of the house and don't progress any further until she is good there.
Any time you go too far, recognize your mistake and ease back on the distraction. Build good habits.
If she won't take food, withhold a meal before you know you are going into a difficult situation. Then the rewards will have more value and the effect will be greater.
When a dog saves the life of a man, it becomes clear that partnership knows no bounds.
