Although animal behaviorists have testified that any dog, trained and properly socialized, would not exhibit any more dangerous characteristics than any other breed of dog, some breeds just have a bad reputation. These breeds have been forced to succumb to their bad habits or natural instincts. For example, the pit bull, when forced to take his ability to hunt and lock his jaw around prey to the extreme, will let judgment fall to the wayside when deciding on a target. Speaking of Michael Vick…*cough*. Force a chihuahua to focus all of its energy on nipping people’s ankles and that breed will appear on the next updated list. A lot of limpers will be roaming the streets.
In order of most to least US fatalities…
