Video from a traffic camera overlooking the busy Costanera Norte freeway in Santiago, Chile showed disturbing images of a dog wandering on the freeway and getting hit.

Later, in the video, another dog dodges traffic to run to the side of the injured dog. The rescue dog drags the severely injured canine across the inside traffic lane as cars swerve around it.

No motorists stopped to help either dog but the video shows a highway crew finally stopping at the end of the video.

The translation of the announcer is as follows, provided by Azteca America Colorado:

"These images seen from the surveillance cameras show a very common situation with our overpopulated highways. It is normal for us to see dogs run over. In the video, we can see this dog fighting for his life because he was run over by the vehicle.

"What is very touching is to see the very heroic actions of this other dog who is trying to pull him to the side of the highway. We are going to keep seeing things like this until we find a solution to the dogs living on the streets."

It is not known if the first dog survived and a check of Chilean newspapers indicates that the incident was not reported in the papers.
