Meet the firefighters in a town called Bertioga in Brazil.
They are an example of human kindness and show we can all make a positive contribution to the world around us.
Not only do these brave men and women risk their lives daily to save humans they also rescue dogs that have no home.
The firefighters told me the story of when they found an old blind dog wandering the streets.
They couldn’t find his family so they adopted the blind dog and called him Cyclops.
Three years later an old man was walking past the fire station and saw the dog.
He began shouting the name ‘Madruga’ and the blind dog ran excitedly for the man.
The man was the dogs owner and had been so upset when he lost his dog.
Finally they were re-united.
