The title of Eat Dog or Die! refers not to the literal consumption of dogs, but to the will to fight and survive. The book is basically a revenge thriller along the lines of Hang 'Em High. The hero is strung up by baddies arrayed against him in a land squabble, but when he's cut down by rescuers, he quickly goes about ventilating everybody that crossed him. C. William Harrison, aka Chester William Harrison, was mainly a western author, but wrote a few youth books, and two technical manuals, as well as the environmentalist book Conservation: The Challenge of Reclaiming Our Plundered Land, which is funny, because that's exactly what the hero of Eat Dog or Die! aims to do. The violent cover art is by Rafael DeSoto, for Lion Books, 1952.
