The sanctuary was a pet project of Werner Freund, who has since passed away. Freund wanted to teach others not to fear wolves and often spent time walking among the animals wearing a smock soaked in animal fat and blood. The wolves came to recognize him and accepted him as one of their own, according to the Telegraph.
Freund opened the sanctuary to help protect wolves. He worked closely with the animals, going so far as dressing their food up as sheep to allow the wolves to really tear into their dinner, according to the Telegraph.
Freund believed that humans fear wolves unnecessarily.
