Three young girls — Carlie, Lacey and Victoria — were just planning to take a dog named Lucy for a quick stroll in their Atlanta suburb, when they say that Lucy pulled them toward a trail, ultimately getting them lost in the woods. Neighbors, police and firefighters searched for the girls when they didn’t return home — but it took Bell the Chihuahua, who belonged to neighbor Carvin Young, to track them down.
