Penguins were being wiped off of an island by foxes — until these 2 dogs showed up

Penguins were being killed by foxes on an island off the coast of Australia and nearly became extinct, but then two dogs showed up.

The trained Maremma sheep dogs were brought to the island in 2006 to protect the tiny penguins. Not only have no penguins been killed since their arrival, but their population has increased! It’s safe to say these good dogs have been successful on their mission! 🙂
