Can you get her to follow you with the food in your hands BEFORE you let her eat? Maybe you could lead her near a gate to your yard, then move the food closer to the gate every time you feed her, and eventually into the yard.

I don't think I'd let her continue to wander the neighborhood. I'd surely hate to be the one to hit her with my car.

I fed a stray dog for a week, sitting 10 feet from the food until she decided to come to me. She followed me home finally--and had three puppies a few days later.

Patience is the key.
