A makeshift lock on a chain link fence was no match for the dog employees at Mann's Welding call Winston.
The 80-pound pit bull mix managed to break free Sunday. That's when Michael Emerling received a call from police.

Quote from the article:

"When they said he attacked a car," said Emerling, "I wasn't prepared for what I saw." Winston chewed the front bumper of a patrol car completely off, bit through two tires, and left teeth marks in the side panel of the vehicle. The Chattanooga Police Officer behind the wheel was clocking speed when Winston launched his attack.
