You’ll Never Guess – What Is the Most Aggressive Dog Breed in the World


So what is the most aggressive dog breed in the world?  The answer may surprise you.

But first let’s tackle a few concepts.

At PuppyDontBite.com, we try not to stress the importance of breed – at least not when it comes to aggression.  Every dog is so different.  And usually, environmental factors and personality play a much bigger role in aggression than DNA does.

With the right type of training:

  • You can take a cuddly Poodle and turn it into a monster
  • You can take a Rottweiler and turn it into a teddy bear

Dogs are highly social, intelligent, and adaptable animals who take their cues from us.  This is why “most aggressive breed” is misleading.

But certain dogs definitely have a reputation for violence, right?  When we think of vicious canine attacks, the first breeds that come to mind are Pittbulls, Dobermans, and Rottweilers.

This stereotype is a bit unfair.  You see, some breeds are preselected for certain duties because of their size and trainability.  For example, a Doberman Pinscher is a much more believable (and intimidating) guard dog than a Beagle is.  So you’re likely to see more Doberman attacks in the news.

Hollywood movies only reinforce this connection in our mind.

Many of these “stereotypical” breeds are so feared within the public that they’re required to wear muzzles in some regions of the world.  Other breeds are banned altogether.

But What Is the Most Aggressive Dog Breed in the World?

Okay.  So which breed is it?

Is it one of those banned dogs (like the Rottweiler)?

Nope.  Not even close.

According to research from Applied Animal Behavior Science and the University of Pennsylvania:

  • The 3rd most aggressive dog breed is the Jack Russell Terrier
  • The 2nd most aggressive breed is the Chihuahua

And the number 1 aggressive canine breed on the planet?  Are you ready for it?

It’s the Dachshund (more commonly known as a Hot Dog, Sausage Dog, or Wiener Dog).

What.  Really?

This survey included over 6,000 dog owners and looked at 33 separate breeds – including Pitbulls and Rottweilers (both of which scored below average for attempted bites).

Don’t Judge a Dog By Its Cover (or Breed or Size or Fur)

If you have an aggressive Chihuahua, Jack Russell, or Hot Dog – perhaps you’re not surprised by these findings.  And if you have a cuddly Doberman or Pitbull, you already understand the dangers of canine stereotypes.

But for the rest of you, keep an open mind.

Judging a dog’s aggression potential is difficult.  And you shouldn’t rely on breed and breed alone.  Personality and environment are way more important.  And you should focus on picking the right type of dog rather than the right type of breed.
