THE owner of an injured protection pit-bull forked out a small fortune for restorative surgery - after claiming the dog saved his life. Marlon Grennan, 28, says four-year-old Ace once stopped him from being car-jacked at a gas station by attacking the would-be robber. So when his prized dog was left crippled after injuring its knee during training, Marlon didn’t hesitate to fork out $4100 to fix him.
