We are located in the sand hills of southeastern Idaho. We have worked hard to produce good, brave, useful dogs and have some litters to sell occasionally. Our dogs must have the ability to herd large groups of cattle. They must also have correct conformation and the stamina to work long days. We concentrate on lines that are strong workers, good travelers and that have loyalty to their person.
Welcome to Mill Iron S Ranch. We are a working cattle ranch nestled in the beautiful mountains of Southeastern Idaho that specialize in exceptional cattle, good broke horses, and perhaps most importantly,STRONG WORKING BORDER COLLIES!
