The moment a heroic Amazon delivery driver in Las Vegas ran to aid a young woman whose dog was being mauled by a dangerous pit bull was recorded on dramatic doorbell camera.
Lauren Ray, 19, is shown caressing the pit bull only seconds before her own dog walks outside, causing the other dog to become enraged and attack her pet, Max, whom she picks off the ground.
Ray cries as she tries to keep the pit bull away from her scared white dog, but Amazon employee Stephanie Lontz jumps in to help by putting herself between the resident and the rampaging canine on her rounds.

"Bad dog!" shouts Lontz as she leaps from side to side to keep the pit bull at bay as Ray hurries her dog back inside.
