From fighters to friends, Vick's pit bulls learn new life

His back resting comfortably against her chest, Hector nestles his massive canine head into Leslie Nuccio's shoulder. The big dog -- 52 pounds -- is social, people-focused, happy now, it seems, wearing a rhinestone collar in his new home in sunny California. But as Hector sits up, deep scars stand out on his chest, and his eyes are imploring.

Hector ought to be dead, Nuccio knows -- killed in a staged fight, executed for not winning or euthanized by those who see pit bulls seized in busts as "kennel trash," unsuited to any kind of normal life. Instead, Hector is learning how to be a pet. (CNN)
