The Chechen's Rottweilers

The Chechen's Rottweilers were a pack of vicious attack-dogs, owned by The Chechen.

A Rottweiler attacked Batman, resulting in a hideous scar and more protective gear.

Towards the end, the Joker had The Chechen taken away, cut up into pieces and he was apparently fed to his dogs.
