Despite having been domesticated for thousands of years, a dog’s size, strength, origins and environment often lend to its aggressive nature. How a dog is treated will often dictate its response — in other words, if a dog is abused and feels threatened, fearful or hurt, it can act out.
On the other hand, with the proper socialization, training and love, every dog can be a loyal family companion and best friend, including the breeds on this list. While studying several resources in researching the most dangerous dog breeds, these are the 20 that came up most often, and many of them are on the banned lists or uninsurable lists.
However, any dog has the propensity to be dangerous without the proper training and treatment, just as much as they can make wonderful family pets with it.
