Chihuahua
Seeing this breed at the top of the list probably conjures up a certain image. Often referred to as "little devils," Chihuahuas may look adorable—especially when they’re asleep—but they may not be the best choice for households with small children.
Naturally territorial and eager to be the center of attention, Chihuahuas can be surprisingly aggressive and stubborn, especially if they feel threatened in their status.
Rottweiler
Rottweilers are 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 behavior.
Although they can be good with children, it's important to closely supervise interactions, as Rottweilers might misinterpret rough play as a genuine threat.
