The 20 Most Dangerous Dog Breeds

20 most dangerous dog breeds

It is hard to say that there are specific breeds of dogs that are dangerous. The way that a dog turns out depends on how the dog is raised, how he is treated, and his living conditions. That being said, there are some breeds of dog who are more prone to aggressive behavior than others. This doesn’t mean in any way that these breeds are going to turn into aggressive dogs with a mean streak.

It just means that if they are treated poorly, they will be more likely to become aggressive than other breeds of dog. Under the right conditions, the dogs on this list can be loving, happy, family pets.  That said, The Journal of the American Veterinary Association (JAVMA) conducted a study that took place over 20 years to determine which breeds were the most dangerous based on bite fatalities.

Most of the dogs on this list were also found in the final results of the study.

Labrador Retriever

20. Labrador

The Labrador is generally a friendly, easy going, and lovable dog. If these dogs are not properly trained and treated well, however, they can be very dangerous. According to the Merritt Clifton Dog Bite Statistics, between 1982 and 2014, there were 56 attacks that resulted in serious injury. Of that number 17 were children.

Also, this breed is responsible for causing one death during this time period. In 2011, a three year old boy was mauled by a Labrador, which resulted in very serious facial injuries. As with any dog, it is the owner’s responsibility to make sure that their dog is loved, properly trained, and properly cared for. Proper care can prevent a deadly attack.

19. Cocker Spaniel

It is very surprising, but this dog actually belongs on this list. At first glance, and if he is trained and treated well, he makes a great and lovable family pet. These dogs are, however, very emotional. Because of this, poorly trained dogs tend to attack. According to JAVMA’s study, the Cocker Spaniel has been responsible for over 59 fatal attacks over the last 25 years. In 2016, an elderly man in Jacksonville, Florida was attacked by a pack of stray dogs, and at least one of them was identified as a Cocker Spaniel. The man didn’t make it.

Tosa Inu

18. Tosa Inu

This is a very dangerous breed of dog as it is known to be a fighting dog. It is also a very rare breed. Because this dog is so dangerous, it has been banned in several countries including the UK, New Zealand, Denmark, Norway, Hong Kong, Australia, and many others. The reason for the ban was due to the increasing number of attacks on humans, especially children. Twenty years ago, the number of attacks was in the thousands. Since the ban has been placed on owning one of these dogs and because there are almost no breeders left, according to the ASPCA, there has only been one attack by this breed in the last three years.

bullmastiff

17. The Bullmastiff

The Bullmastiff is a very large, very muscular dog. He can weigh up to 130 pounds and he can grow as tall as 27 inches. Unless these dogs are well trained and well behaved, they can become violent. Poorly trained dogs can become very unpredictable. In 2014, a 13 year old boy from New Jersey was attacked by a Bullmastiff and he was fatally injured. Another boy was also attacked and he was severely injured.

According to the Merritt Cliffton Dog Bite Statistics, there were 111 attacks in a 15 year period. Of that number, 46 were children and 63 of the attacks were fatal. With proper care and training, however, these dogs can make excellent family pets.

Malamute

16. Malamute

The Malamute is often mistaken for the Husky. These dogs are very large, and they can weigh up to 85 pounds. These dogs tend to be passive and they make excellent work dogs. Like the Husky, the Malamute is known for pulling sleds in the blistering cold. Because of their size, they are not the best pet to have around young children. According to the JAVMA study, this breed was responsible for 12 fatal attacks during a 20 years period.

In February 2014 in the UK, a woman’s six month old daughter was killed by the family’s Malamute. On the other hand, in Cornwall, UK, a man was walking his Malamute when a “pit bull-like” dog started to attack him and his dog saved his life.

st. bernard

15. The Saint Bernard

If you have ever seen the Beethoven movies, you think of a Saint Bernard as an intelligent, protective, and loving family pet. This is actually true. This breed of dog comes from the Italian and Swiss Alps and has become famous for his ability to rescue hikers who became stranded on the snowy mountains. While these dogs can be friendly and protective, they can also be very territorial. If you want to keep a Saint Bernard from growing up and displaying territorial and aggressive behavior, you need to start socializing him with strangers and other animals at a young age.

As long as this breed is trained properly, he can be a great dog. If he isn’t, he can be potentially dangerous due to his size and aggression. The average weight of this breed is between 140 and 260 pounds. The largest can reach over 310 pounds. If this dog is trained to be aggressive, he can do a great deal of damage considering he weighs so much. According to JAVMA’s study, there were only 7 fatalities from a St. Bernard attack during the 20 year period.

The number of attacks is likely much higher, and many go unreported. In July 2016, a Canadian woman was walking by a bus stop when a Saint Bernard at the end of a leash began attacking her. According to the victim, the attack was unprovoked and she ended up losing a lot of blood. She needed 40 stitches and her kneecap was broken. It is not known what type of home life the Saint Bernard had, however, it was the size and the strength of the dog that made it difficult for the owner to pull the dog off of the victim.

American Bulldog

14. The American Bull Dog

The American Bull dog is incredibly muscular and he has a stocky build. He can weigh between 60 to 120 pounds, which packs a great deal of power behind his muscular body. He was originally bred to work on a farm where he would help his master catch and hold cattle and wild boar. He would also kill the vermin that tried to take over the farm and he would guard his master’s property. Today, he is more of a family dog.

Like any dog, with proper training, he will be friendly. He is a very confident dog, which can cause him to be stubborn at times. He also has a very emotional personality at times. As long as you can break him out of this behavior at an early age, he can be a loving and friendly pet. In 2016, a 3 year old boy from Halstead, Essex was mauled by an American Bull Dog. The boy didn’t make it and the owner was arrested for allowing the dog to get dangerously out of control.

These dogs typically love children, and many will allow small children to ride on their back like a horse.

If these dogs get the love, attention, and training that they need, they will make a wonderful family pet. According to JAVMA’s study, between the years of 1978 and 1998, the Great Dane had a total of 7 fatalities.

Over those years, there were thousands of attacks and bites that did not result in death. In February 2016, a woman took her four children with her to check on her boss’ four Great Danes. The El Paso woman entered the home with her family, and the children were attacked by all three dogs. All three of the children required live saving surgery. The Great Dane has also been called a hero when a woman was being beaten by her ex-boyfriend with a hammer and the dog jumped in front of the man and saved the woman’s life. The man was arrested and the dog was hailed a hero.

Akita Inu

12. Akita

Unfortunately, a higher percentage of these dogs are likely to be dangerous and to attack humans and small animals.

The JAVMA study listed 14 fatalities and 364 attacks. The actual number of attacks may not be accurate, as some dog bite incidents are not reported. In May 2013, a neighborhood Wolf Hybrid turned on a 5 year old boy, causing serious injury. In 2009, a Wold Hybrid took a sleeping baby from his crib and the baby died. Many people blamed the dog, considering that he is part wolf. Others blamed the owners for not properly training their dog.

This is the only dog on this list who can become aggressive and dangerous, even under the best conditions, only because he has the genetic makeup of a wild animal.

Many states consider this breed, “unacceptable”, and they require that the owners carry a special insurance to cover any damage that these dogs can cause. If they are not able to get the exercise that they need and they cannot be physically active due to lack of space, they can become very aggressive and dangerous. There are Chow Chows who have risked their lives and proven that these dogs aren’t all bad. Chow Chow, Jared, proves this point.
