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. The breed is known for its strength, loyalty, and controversial history regarding breed-specific legislation.

    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.

    The comments make me so sad. Pit bulls aren't born bad dogs. In fact, they aren't bad at all.

    However, people buy them because of their sturdy build and strong jaws, then train them to become killers. They're all very sweet, cute, energetic, and extremely loyal!

  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. While they can sometimes be aggressive, Chihuahuas can also be lovable, especially if trained from birth or known from a young... 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 historical uses was to herd livestock and pull carts laden with butchered meat to market. Today, Rottweilers... read more

    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 in English is German Shepherd Dog. In Britain and Ireland, it is also known as the Alsatian, a name that was used more commonly during the 20th century.

    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, also known as the Dobermann or Doberman, is a medium-large breed of domestic dog originally developed around 1890 by Karl Friedrich Louis Dobermann, a tax collector in Germany.

  6. Chow Chow

Characterized by a dense double coat and a distinctive blue black tongue, the Chow Chow often has a lion like ruff around its head and shoulders. Weighing between 45 and 70... read more

    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. Jack Russell Terrier

    The Jack Russell Terrier is a small terrier breed originally developed for fox hunting. It is predominantly white-bodied with smooth, rough, or broken coats. The breed is known for its high energy, intelligence, and strong hunting instinct.

    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.

    The Dachshund is a short-legged, long-bodied hound-type dog breed with floppy ears and short fur. It comes in a variety of colors and coat types, including smooth, longhaired, and wirehaired. Although popular as pets, Dachshunds are not considered 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!
