Talk about a nightmare. A man by the name of Tommy Berglund was hunting moose with his dog Klara, when the next thing he knows she disappeared into the woods. As this came from a Swedish hunting magazine, Svensk Jakt, we can only assume this happened somewhere in Sweden.
When Klara returned, the poor girl was bloody with bite marks all over. Upon watching the GoPro footage he discovered she had been attacked by a pack of wolves. Fortunately a vet was only around 20 minutes away, and after three days Klara was able to make a full recovery.
