How do you stop your Rottweiler from snapping at your wife?

To stop your Rottweiler from snapping at your wife, first ensure that the dog feels secure and is not threatened. Use positive reinforcement training techniques to reward calm behavior and obedience. Gradually introduce supervised interactions between your wife and the dog, allowing them to build a positive relationship. If the behavior persists, consider consulting a professional dog trainer or behaviorist for tailored guidance.
