Top 10 Most Aggressive Dog Breeds

This is a list of the top ten most aggressive dog breeds.

The Top Ten

1 American Pit Bull Terrier American Pit Bull Terrier The American Pit Bull Terrier is a dog breed. It is a medium-sized, solidly-built, short-haired dog whose early ancestors came from the British Isles.

3 percent of the dog population, 50 percent of fatal attacks - Murphdog405

Its only dangerous IF its trained to kill. On the other hand, this shouldn't be at the top of the list. Its plain wrong. - IceFoxPlayz

Not true. Pitt Bulls are hunting and bull baiting breeds. They are even considered master of dog fighting. If a Pit Bull were to fight a wild wolf The Pit Bull would kill the wolf. Studies also show that Pit Bulls make up 1/3 of all dog attacks in America. Studies also show that Pit Bulls are most likely to turn on their owners as well. They're more prone to aggression as I mentioned earlier they are a bull baiting and hunting breed. The Pit Bull has a tendency to lock on to its prey in a vital organ and shake until it's dead. - RobertWisdom

Because they are strong, intelligent dogs that are eager to please, pit bulls can be made into highly aggressive killing machines. That said, reputable studies clearly demonstrate pit bulls are not inherently aggressive. In fact, pit bulls are less aggressive towards people than average which makes them relatively poor guard dogs unless they are trained for that purpose.

They kill more people a year than spiders do in the US. I'm not saying all pit bulls are aggressive, their not. But they are much more prone to aggression than lots of other dog breeds. But its proven that chihuahuas are more aggressive, but I would rather have a aggressive 6 pound chihuahua than a tearing aggressive 80 pound pit bull. - BlueberryCatfish

2 Rottweiler Rottweiler The Rottweiler is a breed of domestic dog, regarded as medium-to-large or large.The dogs were known in German as Rottweiler Metzgerhund, meaning Rottweil butchers' dogs, because one of their uses was to herd livestock and pull carts laden with butchered meat to market.

They are featured in Grand Theft Auto 5

These dogs KILL maybe...

We are owning a Rottweiler in my house, and she is not aggressive at all

I have one named spot. He was mean and scary at first but he saved mah life! I'm allergic to bees and I whacked a nest with a stick on accident...bees came out and well... SPOT TO THE RESCUE! He pulled at my sleeve and then attacked those bees, began barking super loud until my mom woke up and set bug spray down! He's still a little agressive today.

3 German Shepherd German Shepherd The German Shepherd is a breed of medium to large-sized working dog that originated in Germany. The breed's officially recognized name is German Shepherd Dog in the English language. The breed is known as the Alsatian in Britain and Ireland.

These things are more dangerous than a pit bull and bigger too.

Only aggressive towards black people. - Murphdog405

I've owned 2 German Shepherd dogs at different stages, both adult dogs when they first came to live with me, and neither of them were aggressive. They never bit nor attacked anyone and they were great with children. However, there are people who are scared of German Shepherds which is ridiculous. Mind you, I would never approach nor touch a German Shepherd dog I didn't know. Treat all dogs with the respect they deserve and they will repay you with love and devotion a gazillion times over.

German Shepherds can be trained to be aggressive but from my experience, they are not naturally aggressive... my German Shepherds were not trained to be aggressive & they never attacked or bit anyone. They're the most intelligent, devoted, loving, loyal dogs in the canine kingdom.

5 Doberman Pinscher Doberman Pinscher The Doberman Pinscher, or Dobermann, or Doberman, is a medium-large breed of domestic dog originally developed around 1890 by Karl Friedrich Louis Dobermann, a tax collector from Germany.

If a Rottweiler and a Doberman bred, would they have puppies that look just like them due to the parents having similar coats and patterns?

The Doberman is a tall and confident dog. Its coat is very similar to the rottweiler. - Awesomelionking

No this is not true. I had a jack russel he passed sadly. And I still cry to this day thinking about him. - Gravityfallsfan11

They aren't really very aggressive. I have one and he's fine. Yeah, he sometimes snaps, but he's a puppy and still learning. Huskeys and Akitas are way more aggressive.

There are friendly dogs in every breed. From what I’ve seen, the Siberian huskies are one of the most caring breed of dog, but because they’re so active, I would watch them around a little kid just to make sure they don’t knock them down by accident. - 3DG20

23 Labrador Retriever Labrador Retriever The Labrador Retriever, also Labrador, is a sporting dog bred for aquatic game. The Labrador is one of the most popular breeds of dog in the United Kingdom and the United States.

I'm not so sure if this is the right type of dog that I'm talking about, but I'm just gonna post it here. So one day I was walking home from the bus stop, when all of a sudden a black lab dog just came booking it out of his fence and bit me near the waist. I actually had to hide behind a neighbor's car while the neighbors fought it off. There was also this brown dog who was a lot more cowardly than the black one. But after this event, I was TRAUMATIZED. I have cynophobia now.

I have a uncle with a black lab female. She attacked my dog and was very aggressive over a play toy they were using. But she is very sweet towards me and other people, she just struggles with aggression towards other dogs. But generally I'm not fond of labs. - BlueberryCatfish

Some Labradors are pretty mean

Maybe but they have to get a hold of it first, you must live in Middle East. Pits will get the neck or belly first, will fight to exhaustion, while kangal bleeds out, that's like fighting a elephant with a lion
