"I didn't see no sign, 'Beware of dog' and I parked my truck about ten feet from the house," said Gillis. "The trailer door was open, I thought maybe the subject might be home. So I walked up to the door, no sign of dogs. I said, 'Hello, Hello.' And I turned to leave for my truck the pit bull came charging on a chain maybe about 20-feet long. That's when he latched onto my arm and I started screaming help, help."
