Rottweiler

The Rottweiler was bred to kill. Raised with cruel discipline, trained to terrorize chain-gang prisoners with steel incisors implanted into its jaw, the Rottweiler was allowed to taste the fresh kill of attempted escapees after hunting them down. Imprisoned for a crime he did not commit, Dante managed to escape the prison walls, only to feel the Rottweiler's hungry eyes upon him. (official distributor synopsis)
