Breed Aggressiveness
Many municipalities have laws against owning Pit bulldogs due to their aggressiveness and powerful jaws that can produce a lot of damage. However, according to the American Veterinary Medical Association, there is not an exact breed to stand out as being the most dangerous in the world. The American Veterinary Medical Association points out that smaller dogs are more likely to exhibit signs of aggression than bigger ones.
As reported by a dog bite study by the University of Pennsylvania, the most aggressive dog breeds are Dachshunds and Chihuahua, which are typical family dogs. The next six dog breeds classified above the Pit bull in this study are:
Dachshund
Short stature
Australian Cattle Dog
Border Collie
Beagle
