When Torgeir Berge's dog, Tinni, struck up a friendship with a fox in a Norwegian forest, he saw an opportunity to educate people about the realities of the fur industry.

Berge photographed Tinni and Sniffer the fox as they played, and with the help of his friend Berit Helberg, he wrote a book about the unlikely friends.

That book now has an accompanying song that was written and performed by Helberg. Take a listen to the video.
