Vampires have a long and unpleasant history of persecuting, oppressing and hunting werewolves, whom they consider to be inferior beings. As such, vampires have been known to abduct werewolves and force them into "dog fights". One werewolf is pit against another in a brutal fight to the death. The winner keeps fighting, held captive in human form the other 29 days of the month, while the loser dies.
The Werewolf Fights are an ancient and lauded vampire tradition. The Dutch show a particular interest in them upon their awakening from their fifty year sleep.
