A new way to protect sheep
The Swiss authorities are experimenting with a new way of protecting sheep flocks from wolves: llamas could be used in some cases to replace protection dogs, which are frightening hikers in remote mountain areas.
Llamas are being tested as part of a pilot project in 12 alpine areas. Swiss TV visited one of the llama guards at Col des Mosses in the canton of Vaud. (RTS/swissinfo.ch)
