A dog police force that is meant to sniff out drugs, and bad guys. They know how to attack and send their opponent on the ground bleeding and crying and eventually die if there were not their handlers to arrest them and let them bleed out as they give them a ticket for fleeing the law and going 5 MPH over the speed limit in a 80 km/h zone.

But sometimes if your luck they will shoot you before they let the hounds loose on you. Just like Mr. Burns from the Simpsons who always lets the hounds loose on trespassers like Girl scouts and orphans!
Example 1:
Mark: Why you running
Kevin: Cause the K-9's are after me
Mark: You better run they bit off Matt's balls last week!

Example 2:
Burns: Release the hounds!
Smithers: Their out for cleaning
Burns: Well you go get them then!
Smithers: Right away, Sir! Bark!
