Vicious

 IT WAS SUPPOSED TO BE A QUIET, RELAXING, WEEKEND GETAWAY... The cabin is not deserted. It is the summer retreat of Jeremy Liden, an author who has just started to taste the fruits of success and the good life, which includes the summer cottage in Wisconsin. The same weekend Jeremy and his friends decide to get away from it all two dogs seek shelter beneath the summer house porch. Two dogs who have been trained to fight. Trained to Attack. Trained to kill. What Jeremy and his friends find at the house is sheer, snarling terror, and as things get desperate, they begin to wonder if they will ever get out alive. Nature made these dogs, but man made them VICIOUS.
