See the moment a Rottweiler saves Chihuahua from vicious coyote

This dog is sending a message not to mess with its little buddy.

Check out this amazing video of a dog rescuing its neighbor, captured by a closed-circuit television. When Trixxie, a chihuahua, is left alone momentarily in her driveway one morning, a hungry coyote discovers her. Just when you think the story is going to have a tragic ending, Happy, the neighbor's Rottweiler, swoops in to save the day. At the sight of Trixxie's large companion, the coyote quickly changes his tune and skadaddles.

John Pettit, who uploaded the video, said that this happened in the middle of a city with no prior history of coyote attacks. The video was uploaded in 2010 but just went viral.
