While dogs are extremely loving, they can also be big, aggressive, and terrifying for some people. It is important to remember that dangerous dogs come from poor environmental upbringing; it is the owner that makes the dog that way and not the dog that makes the owner. Here are the top 9 most dangerous and scariest dog breeds.#1. Dobermann: the Dobermann can be considered a Frankenstein monster breed. This breed was created in the 19th century by a tax collector named Karl Friedrich Louis Dobermann in Germany. He wanted to create a dog that would protect him in confrontations with dangerous people. He achieved this by mixing Rottweiler, German Pinscher, and Beauceron. The hybridization of these breeds created a 28inch tall, 80pound breed which he aptly named after himself. While the Dobermann has been used in all kinds of aggressive jobs, they thrived in the role of protective services. They are used in guarding businesses, hunting down criminals, and even rescuing injured soldiers on the battlefield. #2. Wolfdog: As the name implies, the wolfdog is a mixture of wolf and domestic dog breeds. Dogs and wolfs have been bred in nature for hundreds of years. While domestic dogs are no longer a part of the wolf category, they do share almost 100% of their DNA, making them very easy to breed together. The Wolfdog came about by breeding grey wolves, timber wolves, and Ethiopian wolves with dogs like Siberian Husky, German Shepherd, and Alaskan Maltese. Weighing in at over 100pounds and standing nearly 3feet tall, you can easily spot a Wolfdog from far away. Bans were originally placed on Wolfdogs due to their bad temperament and bad reputation. In recent years, many have come forward, stating that Wolfdogs have been unfairly vilified for their temperament. #3. Great Dane: While Great Danes are gentle, many are afraid of them because of their sheer size and their complex breeding history. The breeding history of the Great Dane is long, starting in the 1600s in Germany with the crossbreeding of Irish Wolfhounds and the great English Mastiffs. Representation of the Great Dane can be found in Egyptian physical monuments and Chinese literature. Typically bred for their ability to hunt boar, they became popular due to their size, tenacity, and intelligence. Eventually, Danes even found their way into European royalty. #4. Pit Bull: Pit bulls were created by crossbreeding bulldogs and terriers. While the Pit Bull can be incredibly cute, they come with a dark reputation and a history that is chalk full of brutality. Used exclusively in England for blood sports like bear baiting and bull baiting in the 1800s, they were eventually pitted against one another. This only came about because bear and bull baiting was banned in 1835. #5. Rottweiler: the Rottweiler originated from Germany and was named after the city it came from, Rottweil. It is one of the oldest dog breeds. Some believe that it was crossbred from the local dogs with ancient Roman Mastiffs in order to drive carts and herd livestock, earning the nickname, Butcher’s Dog. Being bred for their strength, Rottweilers attained large sizes that makes them one of the most intimidating breeds in the world. #6. Canary Mastiff: The Canary Mastiff ‘s history dates back to the 16th century when it was bred in the Canary Islands by the Spanish or Portuguese conquistadors. This breed is known for its ferocity, unique coat, and their weight. These dogs would weigh in over 100pounds and were unmistakable due to their size. Thought to be from the crossbreeding of Sheep Dogs and Bulldogs, the Canary Mastiff was used as guardians, dog fighters, herders, and hunters. #7. Bullmastiff: the Bullmastiff is a powerful and ginormous breed. Originally crossbred by game keepers who wanted to keep rich and noble estates safe during the 1800s, the Bullmastiff ended up becoming an aggressive breed when provoked. In order to create this breed, game keepers used English Mastiffs with Old English Bulldogs which resulted in the large, strong, and fast, Bullmastiff. In South Africa, Bullmastiffs were used to guard diamond mines. #8. Dogo Argentino: while the fear of this white dog breed is reserved to South America only, it is on par with that of the Pit Bull. Dogo Argentino was bred in 1930, by Antonio Martinez, who wanted a big dog for hunting wild boars. The Dogo Argentino was created by crossbreeding the Cordoba Fighting Dog with the Bull Terrier, Great Pyrenees, the Pointer and the Great Dane. #9. Boerboel: while this breed came from the Dutch, it was crossbred in South Africa. The other name for the Boerboel is South African Mastiff and is nicknamed as “Farmer’s Dog”. In South Africa, there are a lot of farms, a lot of massive predators, and people want to protect their land, crops, and homes from intruders, so Boerboels were used. The South African Mastiff’s ancestry is unknown, but other Mastiff types, Terriers, and Hounds were in the South African region when the Boerboels emerged.
