About the family of Livestock Guardian Dogs...
“To this day flocks are guarded in the hills of Asia, Europe and Africa* by powerful, robust dogs that are neither clumsy nor pacific. Despite the distances that separate them these breeds have much in common, and the Kuvasz is a member of this extended sheepdog family.”
