Chihuahua
Seeing this breed at the top of the list probably brings a specific image to mind. Often nicknamed the “little devil,” Chihuahuas may look adorable—especially when they’re asleep—but they might not be the best choice for households with young children.
Naturally territorial and eager to be the center of attention, Chihuahuas can be surprisingly aggressive and stubborn, especially when they feel their status is being threatened.
Rottweiler
Rottweilers are well-known for their large size and cattle-herding abilities. Their natural courage and loyalty to their owners often make them protective, which can be intimidating to strangers and sometimes lead to aggressive behaviors.
While they can get along with children, it's important to carefully supervise interactions, as Rottweilers might misinterpret rough play as a genuine threat.
