Dachshund
Surprise! According to a recent study, this small normal dog was recognized as the most aggressive breed in the world. And despite the fact that the dachshund can not cause serious harm to humans, no matter how much they bite, this little monster is known for its hatred of strangers. As it turned out, one of the 5 taxis at least once in a bite stranger, and one of the 12 - attacked its own master.
Chihuahua
On the second place is another breed, which hardly anyone can take seriously
Rottweiler
Rottweiler is one of the most popular breeds in the world. These four-legged are really amazing dogs.
Chow Chow
Chow-chow look attractive and cute. But it is not so. Adult chow-chow does not apply to dogs you can trust, especially when it comes to children and strangers: they are very irritable and their right to food is proven by aggression.
Pitbull
While rock fans often praise the character, softness and friendliness of the pit bulls, no one can deny that the pit bulls still have aggressive instincts.
