Mang Dieke stepped outside the Fayetteville, Georgia, Walmart for a work break. That's when a Belgian Malinois jumped out of an SUV parked nearby and attacked him. Dieke tried to get away, but the dog clamped onto him, so he dragged it back into the store, where the dog's handler, a Fayette County sheriff's deputy, finally noticed the commotion and pulled the dog off. Dieke suffered deep bites to his chest, stomach and groin. Sheriff's officials say they don't know why the dog attacked Dieke.
