The ideal Rottweiler is a medium large, robust and powerful dog, black with clearly defined rust markings. His compact and substantial build denotes great strength, agility and endurance.
Dogs are characteristically more massive throughout with larger frame and heavier bone than bitches.
Bitches are distinctly feminine, but without weakness of substance or structure. Correct proportion is of primary importance, as long as size is within the standard' s range. The length of body, from prosternum to the rearmost projection of the rump, is slightly longer than the height of the dog at the withers, the most desirable proportion of the height to length being 9 to 10. The Rottweiler is neither coarse nor shelly. His bone and muscle mass must be sufficient to balance his frame, giving a compact and very powerful appearance.
