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. 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.
