Tracker - Season 1 Episode 6 The Beast

A blind man is led into the middle of an intersection and left to be run over by his German Shephard. While picking up Mel from an aborted date, Cole senses the presence of one of his prisoners, and soon determines the German Shephard has been taken over by one of the last arrivals on the train: Medoran, Zin's bodyguard. Zin is putting his bodyguard to use, killing a councilwoman who stands in the way of his desire to have a district of Chicago rezoned. Cole tracks down the dog, which can shift forms into a werewolf-like humanoid, and manages to capture it.
