Sombody wrote about the polish tatra that they would actively do a killing chase to kill a wolf.

"Esteemed by shepherds, selected in respect of personality traits and of presence the Podhalans do not surrender to pull away too far and for a long time from guarded by them sheep. Returning they make circles with smaller and smaller rays and in moment when they are crossing the trace of the wolf leading the ewe robbed him earlier, they are starting a killing chase. The most difficult task falls to the bravest dog that first has run up the robber. Most often the wolf stands up to the dog and defends furiously his trophy. He is a very difficult enemy and often it happens that the wolf bites the dog painfully. But each and every Polish Tatra Mountain Dog holds his ground even when he has to fight against more than one enemy and tries to endure until another dogs will come running to him relief. The wolf seeing another dogs decides to escape. Saved ewe is escorting to the flock by the dogs."

Are there other accounts of this happening with LGD's ?
