Streeljaw

Steeljaws are wolf-like creatures used by  Lockdown to hunt down intruders and prey that venture into his ship.

Fiction
As Cade, Tessa, and Shane fled Lockdown's ship, the ruthless bounty hunter sent in multiple Steeljaws to find them and kill them. Cade picked them off while Shane and Tessa crossed the anchor wires. While some of the alien attack dogs attempted to terminate the humans (which pretty much just resulted in getting shot), others chewed through the wires and eventually broke them. The Steeljaws watched all of their chewing go to waste as the trio of fleshlings were rescued by a conveniently-nearby  Bumblebee. They probably didn't care much. Why? 'Cause they're animals.
