The ranch is in the grip of a heat wave, and to make matters worse, there's a raging rottweiler on the loose. It's up to Hank the Cowdog, Head of Ranch Security, to teach the visiting pooch some manners. It's rumored that Bruiser is all talk and no action, but when he attacks a defenseless fawn, Hank's not sure what to think. Has Hank got what it takes to take care of this crazy canine? Or are his dog days numbered?
