I found a translation of what the newscaster is saying in the video of the dog risking its own life to save the life of a dog injured on a Chilean freeway.
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.
