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.

They are only aggressive if you raise them to be that way. Sure, they may have an aggressive nature, but if you raise them right, they're actually very sweet and extremely loyal.

Because they are strong, intelligent dogs that are eager to please, pit bulls can be made into highly aggressive animals. 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 trained for that purpose.

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

This is one ferocious breed of dog! Its teeth can rip through human skin.

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

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 my life! I'm allergic to bees, and I accidentally hit a nest with a stick. Bees came out, and well... SPOT TO THE RESCUE! He pulled at my sleeve, then attacked those bees and barked super loud until my mom woke up and sprayed bug spray!

He's still a little aggressive today.

OMG. These dogs are trained to kill! It's basically the same thing as the Pit Bull, but it's not their fault!

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

4 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.

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.

I love German Shepherds, but yes, they are more prone to aggression issues than some other dogs. If not properly trained, they can become extremely aggressive.

My neighbor's German Shepherd attacked and killed my Corgi when I was a kid.

5 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.

The Doberman is a tall and confident dog. Its coat is very similar to the Rottweiler's.

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 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 feel like it. This breed's aggression is rooted in neglect and personality.

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. It tried to bite my leg off!

8 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.
9 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.
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... read more

This breed should be higher than Chow Chow. These dogs are even banned in some countries due to their aggressive nature.

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

There are friendly dogs in every breed. From what I've seen, Siberian Huskies are one of the most caring breeds of dog, but because they're so active, I would watch them around a little kid just to make sure they don't accidentally knock them down.

The Husky is a fast and high-energy dog breed. It is similar to the Alaskan Malamute.

12 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!

13 Manchester Terriers

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

14 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.
15 Cocker Spaniel Cocker Spaniels are dogs belonging to two breeds of the spaniel dog type: the American Cocker Spaniel and the English Cocker Spaniel, both of which are commonly called simply Cocker Spaniel in their countries of origin.
16 Miniature Pinscher The Miniature Pinscher is a small breed of dog originating from Germany. The breed's earliest ancestors may have included the German Pinscher mixed with Italian greyhounds and dachshunds.
17 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 Malamute is a sled dog, just like the Husky. The Alaskan Malamute has a very similar coat to the Husky.

18 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.
19 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.

Bruh - they would only be aggressive if trained that way.

20 Boxer The Boxer is a medium-sized, short-haired breed of dog, developed in Germany. The coat is smooth and tight-fitting; colours are fawn, mahogany, black or brindled, with or without white markings, and white.

The Boxer is an average strong dog that has an average size.

22 Cane Corso A breed of Italian origin, the Cane Corso is a large and powerful mastiff used for guarding property and as a companion animal. It has a short coat and is distinguished by its keen intelligence and trainable nature.
23 Perro de Presa Canario The Perro de Presa Canario, A.K.A. the Canary Mastiff, is a large Molosser-type dog breed originally bred for working livestock.

They are very strong and are only raised to be guard dogs, not family ones.

24 Yorkshire Terrier The Yorkshire Terrier is a small dog breed of terrier type, developed during the 19th century in Yorkshire, England, to catch rats in clothing mills.

My aunt has one, and it hates me. It jumped on me and tried to bite me twice, even though I never provoked it!
