Chihuahua

Seeing this breed at the top of the list likely conjures a specific image. Often dubbed “little devils,” Chihuahuas, while adorable – especially when sleeping – 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, particularly when they feel their status is threatened.

Rottweiler

Rottweilers are renowned for their imposing size and their innate abilities in herding livestock. Their natural courage and unwavering loyalty to their owners often lead to a protective demeanor, which can be intimidating to strangers and, at times, may result in aggressive behavior.

While they can get along well with children, it’s crucial to closely supervise their interactions, as Rottweilers might misinterpret rough play as a genuine threat.
