they're just dogs with a metallic plating around the head. They're Omnivores, meaning when they can't hunt, they can feed on plant life, and Copperhead Valley and the surrounding desert has random growth spurts of tough grass. These things collect in herds and roam to follow the movements of prey, burrow for lizards, insects and snakes, and hope to stumble on the plant growth.<br/><br/>They're the reason its called Copperhead Valley. Some of them even make good pets :) its only when they live in the wild that their suspectible to the mood swings of E-Ther damaged environment, so if brought up right, they can be quite placid.
