But because of its huge size, it becomes very easy for a Great Dane to become bossy and dominant if undisciplined.

The Argentine Dogo was developed by Dr. Antonio Nores Martinez in the 1920s who wanted an ideal companion dog that was also a good hunter. The breeds that were used were the Great Pyrenees, Irish Wolfhound, Pointer, Great Dane, Dogue de Bordeaux, Boxer, Spanish Mastiff, Bulldog, Bull Terrier and the now extinct breed called the Dog of Cordoba. The result was a large, muscular white dog which was soon used for dog fighting. This, once again, gave the dog a bad reputation and it has since been banned  in numerous countries such as Ukraine, Iceland, Australia and the UK.

German Shepherds are used by the police force for good reason - they are strong, intelligent, confident and incredibly loyal. However, caution must be exercised with German Shepherds as they can become overprotective of their family and territory, and if not socialized correctly, can easily attack. German Shepherd attacks on both people and other animals are worryingly common, which places them in 4th place for the most dangerous dog.

The Siberian Husky is a medium-sized working dog breed that originated in Siberia, Russia. Generally speaking, a Husky is very friendly and loyal to people. However, they possess a strong natural predatory instinct and can be very dangerous to other animals. This breed is incredibly intelligent, but factors like improper training, poor socialization and bad social experiences can turn them aggressive to both animals and people. In 2012, a newborn baby was mauled to death by a Siberian Husky in Canada.

Rottweilers are eager to please and easy to train, but despite their good nature, they are powerful dogs that require early socialization and lifelong obedience training. Rottweilers often find themselves in the news for maulings and killings, which makes them number 2 for the most dangerous dog. However, Annie Colbourne from the Rottweiler Welfare Association says Rottweilers are "beautiful, faithful and intelligent", and make good pets as well as guard dogs - in the right circumstances. She says, "People get a Rottie and think 'OK I've got my big dog, here it is', well that big dog has a big brain, and that brain needs to be kept active".

Ranking number 1 for the most dangerous dog in the world is the Pitbull. Pitbulls are the most notorious for maulings and killings. They have been bred to be aggressive, and are the main dog of choice in dogfighting. Through selective breeding, Pitbulls have developed enormous jaw strength, as well as a "hold and shake" bite style, designed to inflict the maximum damage possible. No countries except Canada and the US allow the importation of pit bull type dogs.
