ABOUT: Serbian Defense Dog Ben Akiba 4 month\r\nThe Serbian Defense Dog is a re-creation of the old Serbian Mastiff of the Middle Ages.\r\nIt was developed by Nenad Gavrilovic, a Bosnian herbalist and medicine man in the early 1980\\\'s, but the final standard was written in 1991. Using his domesticated pack of Serbian wolves, working Bosnian Tornjaks, German Rottweilers, Neapolitan Mastiffs, American Staffordshire Terriers and game-bred Pit Bull Terriers, Gavrilovic created a breed of immense physical strength, fantastic guarding instincts and impressive fighting abilities.
