25 Most Dangerous Dog Breeds

Posted by on August 1, 2013

There are many factors that play a role when assigning a “danger” level to a dog but most critics and researchers disagree as to what these factors are. Consequently, it’s unfair to callously label a dog as dangerous. Nevertheless, it can’t be helped that some dog breeds have more potential to cause serious harm to a person if the dog were to decide to attack. Therefore, our 25 most dangerous dog breeds focuses on the potential of a dog to cause serious injury to a victim. It is important to note however that most dogs are bred with the desire to please their masters. Thus most incidents involving dogs stem from improper training and harsh ownership.

    I would as I had a Basenji. They are something and you would not believe what they can and will do unless you see it for yourself. One thing puts the Basenji ahead of most of these dogs is its intellect – the dog actually thinks and moves two or three moves ahead of its victim/prey I would never have another one.

    They are most dangerous animals on this world

    The only reason a pitbull would attack is if it has a crappy owner. Otherwise they’re the best dogs in the world

    I think the problem here is that the title of this list is misleading. Saying that these are the 25 most dangerous dogs implies that each and every one of these dog breeds is prone to being aggressive. That’s not necessarily true. A more accurate description would be something to do with 25 dogs breeds with the most potential to cause harm. As a Great Dane owner I was a bit shocked to see the breed on a list of dangerous dogs, but looking at it from the perspective of what my dogs COULD do, just based on size, I can see why they are there. This does not in any way mean that they would harm someone, just that, from an unbiased, completely physical standpoint, they could cause some serious damage.

      The Dane is also known as the gentle giant and it has earned that name….

  • Crissty Hopkins

    Where in the hell are the small dogs? Clearly this author is a small dog lover, but hates big dogs. I’ve owned some of these breeds and never had a problem! Hate the deed not the breed! Oh and fuck ignorance and intolerance against big dogs and bully breeds! The more people I meet, the more I love my pitbull.

    • Jenny

      I couldn’t possibly agree more!!!

  • Doc Stu

    How is it that a “video game fan that loves tech” qualified in any way to write a list about dangerous dog breeds (which is a ridiculous topic in the first place)? C’mon people… Check your sources of information.

  • Lexie

    No dog is dangerous if you raise it right. My parents had a German Shepard for 10 years, When I was being fostered at 3 months old he would play with me all the time, he was my best friend for 5 years until he passed away in 2006 and and never once hurt me or attempeted to. I understand that not all dogs are like this, but it’s lists like this who make people think that all of these breeds of dogs are dangerous.

  • Robert Galloway

    Grew up in the family of a veterinarian. Haven’t had experience with most of the breeds presented, but still many. Currently share the house with a 110# German Shepherd. My boss before I retired had several Rottweilers. I believe from my experience that it’s all a matter of how they are reared/conditioned. Wouldn’t be reluctant to trust my grand kids with any of the large dogs I’ve experienced. Snappy Scotch Terriers on the other hand… Give me a large well trained dog any day.

    Dogs are generally placid. As long as they have haven’t been antagonised or have had bad memories most dogs will not bite. Also, it depends what you class as aggressive. You would be surprised how many people class violent tug of war, running or even chasing a rabbit as aggression. Around 83% of dog violence is natural responses to something like rabbits would be a good meal to a slightly dominant wolf gene. Basically, dogs are good but get a bad reputation.
