The Rottweiler is a stocky dog with short, coarse black hair. The dog has tan or mahogany marks on its head, chest, and legs. Rottweilers resemble Doberman pinschers. When full-grown, they stand about 27 inches high. Rottweilers were developed in one of the valleys of southern Germany, near the village of Rottweil. They are descended from the camp dogs that followed Roman armies in their conquest of southern Germany about 1,900 years ago. The Romans used these dogs to herd the cattle and sheep that provided meat for the armies.
