Revenge of the Dogs

A spooky, fictional story for ages 10+ about three men and their unwanted hunting dogs.
Pig hunters, Jim, Digger and Isaac, like most serious hunters, owned dogs that knew what to do, whether by instinct or through training. Every once in a while, a dog failed to fulfil its role, and if not suitable as a pet, the dog was put down. Things, however, would come back to bite the men in the butt.
