Video captures the disturbing moment that two pit bulls maul a man after trying to protect his dog. The victim, John Brady, was walking with his dog on Avalon Pier on Santa Catalina Island in California when they were mauled by the pit bull. Brady attempted to protect his dog, Josh, and the pit bulls attacked him so severely that they ripped out a chunk of his calf as well as biting both of his arms. Eventually, Avalon Harbor Patrol officers were able to pull the dogs off of him. Brady was airlifted to UCLA Harbor Medical Centre.
