A Rottweiler is always, by any breed club standards, black with well-defined mahogany or rust-colored markings that do not take up more than ten percent of the dog's body color. All Rottweilers standard to AKC specifications have one mahogany dot above each eye on the inner brow ridge, on the cheeks, one strip on each side of the snout; cheek markings do not cross over the bridge of the nose, the top of the nose should remain black. The Rottweiler is good-natured, placid in basic disposition, very devoted, obedient, biddable and eager to work.
