10 Most Dangerous Dogs In World by Priyanka ,  Jul 31, 2013
Dogs are the perfect companions – exceedingly loyal and unfailingly faithful.  But while they can be your best friends, they can also be your worst enemies. This is particularly true if you do something to threaten their well-being, their owners, or their owners’ property. After all, there is a good reason why canines are also used as guard dogs; they can be aggressive and, in some cases, even fatal.
People believe that pets are our best friends. People love them so much that sometimes they eat together, sleep together, and go for walks together. Many people like dogs because of loyalty and security advantages, some dogs are cute and small but some are big and dangerous. Here is the list of ten most dangerous dogs on earth.

While domesticated dogs are almost always extremely friendly and amicable, on rare occasions, dogs can be dangerous. There are many different breeds of dogs, but the most dangerous dog breeds are quite well known, however looking at the top 10 most dangerous dogs by bite fatalities came up with some interesting results.

The Journal of the American Veterinary Medical Association conducted a twenty year study on the most dangerous dog breeds, and here are the top 10 most dangerous dog breeds based on the amount of fatalities they have caused:

Pit Bulls (Weight: 55-65 lbs.)

Pit BullsPit bull is one of the most brave and dauntless dogs that usually takes on any opponent. Therefore they take part in dog fighting. It is common knowledge that this dog breed can even mangle the human to death as pit bull locks its jaws onto the booty until it is dead.


The Dalmatian is a breed of dog whose roots are often said to trace back to Dalmatia, where the first illustrations of the dog have been found. The Dalmatian is noted for its unique black- or brown-spotted coat and was mainly used as a carriage dog in its early days. Today, this dog remains a well-loved family pet, and many dog enthusiasts enter their pets into the competitions of many kennel clubs. Via

Origin: Balkans, India, Middle AgesHeight: 20-24 inches



(Weight: 50-70 lbs.)

Origin: Germany, 1850-iesHeight: 20-25 inches

Dobermann: Dobermann's were considered one of the most dangerous dog breeds a few decades ago but thanks to careful breeding the temperament of the Dobermann has improved and he is much less likely to be aggressive nowadays. Still a fantastic, loyal guard dog, the Dobermann is still likely to be suspicious of strangers and should be trained properly to avoid overly aggressive behaviour.

Origin: Germany, XIX centuryHeight: 26-28 inches

German Shepherds (Weight: 70-100 lbs.)

German ShepherdsThis breed of dogs is known as a smart and vigilant one. As German Shepherds proved to be confident and fearless local authorities such as the police K-9 unit use German Shepherds as a police dog.

Chow Chow: I was a little surprised when the Chow Chow popped up several times during my research as I had worked at a Chow Chow breeder's kennels and never encountered any aggressiveness from any of the 30 ish chow chows there. But apparently they can be very aloof and independent and fiercely protective of their owners and property. They could raise the cost of your household insurance as they are classed as "high-risk" dogs i.e. more likely to bite someone than other breeds.

(Weight: 50-70 lbs.)

Origin: China, antiquityHeight: 18-22 inches

Alaskan Malamutes (Weight: 75-100 lbs.)

Alaskan MalamutesThis breed requires a lot of exercises to be happy as being bored they become disobedient. On the whole their characteristic features are energy and activity.

Next on the list of most dangerous dog breeds is the Rottweiler. This is based on studies conducted by the American Veterinary Medical Association, the Humane Society, as well as the Center for Disease Control. With a weight that ranges from 46 kilograms to 59 kilograms, Rottweilers pack a lot of stopping power that surely no one wants to put to a test.

The territorial instincts of this particular dog breed is second to none, while the power of its jaws is unrivaled by any other dog all across the world. Rottweilers are remarkably smart, but you’ll have to devote a ton of attention and love to them. A poorly trained Rottweiler can be quite defiant and hostile.

The Rottweiler is a large size breed of domestic dog. The dogs were known as “Rottweil butchers’ dogs” because they were used to herd livestock and pull carts laden with butchered meat and other products to market.Some recordsindicate that earlier Rottweilers may have also been used for hunting, although the modern Rottweiler has a relatively low hunting instinct.

Saint Bernard


The St. Bernard is a breed of very large working dog from the Italian and Swiss Alps, originally bred for rescue. The breed has become famous through tales of alpine rescues, as well as for its enormous size.

Origin: Switzerland, Middle AgesWeight: 110-180 lbsHeight: 24-29 inches

Presa Canario: A huge dominant dog bred for dog fighting. These dogs have a very strong character and need to be trained daily until the age of two to help establish a bond with their family. They are suspicious of strangers and there is a woman currently serving 15 years in jail due to her two Presa Canario's randomly attacking another lady in a San Francisco apartment corridor and tearing her to death. Banned in Australia and New Zealand.
