Danny and Kenny visit the police department in Terre Haute, Ind., to test a group of dogs' reactions to live gunfire. One of the animals becomes anxious, and when his handler tries to subdue him incorrectly, he winds up with a vicious bite. The guys have to take the dog back to the kennel to determine if the dog has issues, or if the real issue was poor handling. Meanwhile, Luther has four dogs who he must teach to detect explosive odors in only a few short days before a new Tactical Explosive Detector Dog (T.E.D.D.) class. If he can't get the job done they'll have to work through the weekend, which means no turtling.
