The breed's ancestors were the mastiff-like, cattle-herding dogs of the ancient Romans who accompanied their armies as they swept across Europe. Some of these dogs were left behind when the army moved on, and in Germany, they bred with local sheepdogs and produced the Rottweiler.

This highly trainable breed is quick to learn new tricks and commands. However, despite their trainability, Rottweilers can quickly develop behavioural issues if not properly trained and are better suited to more experienced dog handlers.

Take appropriate measures to desensitize your Rottie to his stimuli. Introduce him to whatever bothers him at a slow pace. Use a clicker to mark good non-aggressive behavior and reward him. Always practice caution with your Rottweiler during meetings with other dogs and make sure everyone involved is on board.

Use positive reinforcement and avoid physical discipline and yelling. Rewarding your dog for his positive behaviors is an integral part of the training process. Understand that your Rottweiler will make occasional mistakes and that you must avoid physical discipline or yelling at him in these situations.
