What dog has the most attacks on humans?

Answer 1

It is sometimes argued that certain breeds are inherently aggressive towards humans and shouldn't be allowed at all, or that, due to the popularity of certain potentially dangerous breeds, these dogs are often owned by irresponsible owners who provide insufficient training or, worse, aggressiveness training. An opposing argument is that no breed is inherently aggressive towards humans and that regulating one breed simply moves the irresponsible owners to start focusing on breeds that haven't yet been regulated, moving the problem to other breeds. This is one of the positions taken by the American Veterinary Medical Association.

It is stated that Pitbulls and Rottweillers have the most attacks on human. On the other hand, most attacks are atributed to pitbulls because authorities could not tell the breed and theorefore stating to be pitbulls.
