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 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.

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.

I like American Pit Bull Terriers and all, but they are aggressive dogs. If you want one, you should learn how to handle it responsibly.

Dangerous breed that should not be in households especially with children and smaller pets.

2 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.

3 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.

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.

Seriously, I don't know why my dad love them so much!

The is a very big and strong dog breed.

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

4 Chihuahua The Chihuahua is the smallest breed of dog and is named for the state of Chihuahua in Mexico. Chihuahuas come in a wide variety of sizes, head shapes, colors, and coat lengths.

This is one ferocious breed of dog! It's teeth can rip through human skin.

As much as I love chihuahuas, I wouldn't own one if I had kids.

They are scaredy cats

I've had 2 Chihuahuas attack Randy, but luckily Randy chased them off. I'm very concerned for those dogs, because they were unleashed and they might have neglectful owners. - Joshtition24

5 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.

The person who said German Shepherds are more dangerous than a pit bull is totally wrong. German Shepherds are NOT aggressive but like most dogs, they can be trained to be aggressive but only if they're trained as police/security dogs. My German Shepherds were never aggressive. They were intelligent, loving, loyal, kind & gentle. We treated them well & they treated us well. Once you've owned a German Shepherd dog, you'd never want to own any other breed.

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.

That's only if you don't train them well enough, then they could disobey you and turn aggressive. My tip is to train them early. Do not underestimate this breed, it is very powerful and very intelligent.

6 Chow Chow The Chow Chow is a dog breed originally from northern China, where it is referred to as Songshi Quan, which means "puffy-lion dog".

They're meaner than a Rottweiler. People only adopt them for their looks, and that's obviously the reason why the majority of this breed is untrained and aggressive. Due to their owners babying them, they believe they own everything and bark at anything with no warning. I know there are some actually smart owners who train their Chow Chows, but even the ones that are trained tend to still attack people if they want. This breed is just based on neglection and personality.

They look rude/mean

Ya they are mean.

7 Dachshund The Dachshund is a short-legged, long-bodied, hound-type dog breed with floppy ears, and short fur. Although, this Dog, which comes in a variety of colours, is not hypoallergenic.

I used to like Dachshunds until two attacked my old dog and one tried to rip my cat apart.
They're nasty dogs

One was really aggressive with me. Tried to bite my leg off!

8 Cane Corso
9 Bull Terrier The Bull Terrier is a breed of dog in the terrier family. There is also a miniature version of this breed which is officially known as the Miniature Bull Terrier.
10 Dogo Argentino The Dogo Argentino, also known as the Argentine Mastiff, is a large, white, muscular dog that was developed in Argentina primarily for the purpose of big-game hunting, including wild boar; the breeder, Antonio Nores Martínez, also wanted a dog that would exhibit steadfast bravery and willingly protect more.

Should be higher than Chow Chow. These things are even banned in some countries due to their being aggressive.

The Contenders
11 American Bulldog The American Bulldog is a breed of utility dog. There are two specific types of American Bulldog, Standard and Classic; additionally, there are also hybrids of the two types.
12 Rhodesian Ridgeback The Rhodesian ridgeback is a dog breed developed in Rhodesia. Its European forebears can be traced to the early pioneers of the Cape Colony of southern Africa, who crossed their dogs with the semi-domesticated, ridged hunting dogs of the Khoikhoi.
13 Dalmatian The Dalmatian is a breed of large dog, noted for its unique black or liver spotted coat and mainly used as a carriage dog in its early days.

The Dalmatian is a spotted dog that is tall and has lots of energy. They are good with kids at all.

14 Alaskan Malamute The Alaskan Malamute is a large breed of domestic dog originally bred for hauling heavy freight because of their strength and endurance, and later a sled dog.

The Alaskan malmute is sled dog just like the husky. The Alaskan malmute has a very similar coat to the husky.

15 Jack Russel Terrier The Jack Russell Terrier is a small terrier that has its origins in fox hunting. It is principally white-bodied and smooth, rough or broken-coated.

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.

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

16 Boerboel
17 Bullmastiff The Bullmastiff is a large-size breed of domestic dog, with a solid build and a short muzzle. The Bullmastiff shares the characteristics of molosser dogs, and was originally developed by 19th-century gamekeepers to guard estates.

19 Siberian Husky The Siberian Husky is a medium size, dense-coat working dog breed that originated in north-eastern Siberia.

They are the sweetest little goof balls. I have 2 they are super nice one is named Skye a grey and white 5 month old husky with brown eyes and I have one named Silver a whit whisky with one blue eye and one brown eye is he 1 year old. Great family dogs. I suggest getting one if you are active or if you have a family. Sorry if I misspelled something

I have one named Misty he is not aggressive at all! He is so cute! Yes they might be hyper but when they have no energy they get in cuddly moods. HE IS SOOOO FLUFFY! My younger sister she's 7 I am 11 Misty is great with her and other kids. My Husky likes yo jump and lick but he is not aggressive they are just hyper that's all.

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.

The Husky is a fast and high energy dog breed, it is similar to the Alaskan malmute.

20 Saint Bernard The St. Bernard or St Bernard is a breed of very large working dog from Swiss Alps and north Italy and Switzerland, originally bred for rescue.

Great with kids, but will attack if it has to.

Don't trust them

21 Akita

The Akita is a tall dog that has great hunting skills.

Those things have fat faces..

22 Manchester Terriers

Very similar to the Doberman, obviously the reason why people rarely buy this breed.

23 Pomeranian The Pomeranian is a breed of dog of the Spitz type, named for the Pomerania region in Central Europe. Pomeranian Dogs tend to get sick very often, however.

This little fur-ball is so aggressive!
