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.”
From: Dr. Buzády Tibor, Dogs of Hungary, trans. Bernard Adams, Budapest, Hungary: Nóra Kiadó, 2002, p. 90.
