Once you develop a strong bond with a Rottweiler, they are extremely loving, caring, and loyal. They have an even temperament as long as you behave in a cordial way with them. However, they can get really aggressive if they sense danger. This is what makes them good guard dogs. Their protective nature and powerful barks are capable of intimidating burglars and trespassers. Rottweilers have a well-balanced personality. While they can be calm and gentle with their owners and loved ones, they can get equally aggressive on sensing danger. Also, they are highly alert and intelligent dogs.
