This astonishing video showing a chihuahua being rescued by a rottweiler from the mouth of a hungry coyote was posted in 2010 but only went viral in the past couple days. According to the owner of the CCTV footage, Trixxie, the chihuahua, was tied up outside when she was spotted by a hungry coyote. Only the intervention of the neighbour’s rottweiler, Happy, saved the life of the smaller dog. Credit: YouTube/John Pettit
