According to the American Kennel Club Rottweilers have a natural gathering style with a strong desire to control. They generally show a loose-eye and have a great amount of force while working well off the stock. They make much use of their ability to intimidate.
The Rottweiler often carries the head on an even plane with the back or carries the head up but with the neck and shoulders lowered. Some females lower the entire front end slightly when using their eyes. Males also do this when working far off the stock in an open field. This is rarely seen in males when working in confined spaces such as stock yards.
The Rottweiler has a reasonably good natural balance, force-barks when necessary, and when working cattle uses a very intimidating charge. There is a natural change in forcefulness when herding sheep. When working cattle it may use its body and shoulders and for this reason should be used on horned stock with caution.
The Rottweiler, when working cattle, searches out the dominant animal and challenges it. Upon proving its control over that animal it settles back and tends to its work. Some growers have found that Rottweilers are especially suited to move stubborn stock that simply ignore Border Collies, Kelpies, and others.
Rottweilers use their bodies to physically force the stubborn animal to do its bidding if necessary. When working with sheep the Rottweiler shows a gathering/fetching style and reams directions easily. It drives sheep with ease. In some cases Rottweilers have begun herding cattle without any experience at all.
If worked on the same stock for any length of time the Rottweiler tends to develop a bond with the stock and will become quite affectionate with them as long as they do as it directs.
The Rottweiler is also exceptionally suited for and is commonly used in the dog sport.
