Kill Crazy (1990)

A group of veterans who have been hospitalized for a variety of mental disorders, are taken on a camping trip into a remote wilderness area. What was to have been a time of fun and relaxation turns into terror when they become the victims of white supremacist bullies who stalk and hunt the vets. One of the fleeing vets finds momentary refuge with two women campers and their dog. There is rape, countless gruesome deaths, and much violence in this film. Fortunately, none of it involves the dog, a beautiful and intelligent Rottweiler. His talents include fetching water from a stream with a bucket that he holds in his mouth. This comes in handy later when he uses the trick to revive an unconscious vet.
