Chihuahua
Seeing this breed at the top of the list might conjure up a certain image. Chihuahuas, sometimes referred to as "little devils," can look incredibly cute, especially when they're asleep, but they might not be the best fit for households with small children.
Naturally territorial and always craving attention, Chihuahuas can become surprisingly aggressive and stubborn when they feel their position is threatened.
Rottweiler
Rottweilers are a large breed known for their ability to herd livestock. Courageous and fiercely loyal to their owners, they can be very protective, which may make them seem intimidating to strangers and can sometimes lead to aggressive behavior.
They can get along well with children, but constant supervision is important as they may misinterpret rough play as a threat.
