Although dogs are known to be the humans best friend, they’re not originally meant to be with humans, instead – theyre predators from the wild. They’re very intelligent, good at hunting and can be the ultimate protection for a family. However, there have been reports of well tamed dogs where they have randomly attacked their owners. One should always be aware of what dogs are capeable of, especially some dog breeds that i have listed down below.

1. Caucasian Shepherd

Caucasian Shepherd

This dog comes originally from russia and has been used in the mountains for centuries to protect farm animals. But would it be able to protect the farms from predators such as wolfs? Answer is : Yes. The Caucasian Shepherd can weigh more than 100 kg ( 220lb) And that is weight in muscles. It’s also extremely good at fighting too, no wonder why this breed is so dangerous. It is recommended to stay at least 100 meters away from this dog (at all times).

2. Pitbull


This breed has been banned from multiple countries and has quite a reputation for being a dangerous dog. They have an extremely agressive behaviour, and if they haven’t been in training from the moment they have been born, this is a killing machine. Their capability of fighting have been used in illegal activity such as dog fighting, where the owners would bet money on their dogs and often let them fight to the death.

3. Perro De Presa Canario

Perro De Presa Canario

Made in the Canary Islands. Yes , this was made by mixing several different breeds together to get the perfect fighting dog. There’s no clear evidence that this is true, but considering the dogs capability and the big culture of dog fighting on the island, it’s most likely true. The dog has been banned in several countries for its dangerous behaviour. Many people does however decide to smuggle this dog and possess it illegaly for the use of dog cage fighting. It is extremely dangerous to try to tame this dog as it is not very cooperative with humans. It is more likely to tame you, with its teeth…

4. Rottweiler


If there’s one dangerous dog breed that is responsible for a lot of deaths, it’s this one. Reports have been made claiming that this dog alone is responsible for almost half of all deaths caused by dogs in USA. Their strong bite combined with their amazing jump, makes them capeable of biting a human’s throat. The dog is commonly used for self defence purposes as well as underground dog cage fighting, which is illegal in most countries of course.  Be careful with this dog, seriously.

5. Fila Brasileiro

Fila Brasileiro

If you don’t like agressive dogs, don’t get one of these. This originally brasilian dog was used to hunt wild boars and has an uncontrollable agressive behaviour. Many fatalities have been reported after families have made decisions to adopt one as a family protection dog, which turned completely around against them.

6. Midacet Sula Shephard

Midacet Sula Shephard

A complete mix of unknown breeds, for one goal only – to create the most dangerous dog breed ever. This dog would be the ultimate guarding dog if it wasn’t for its temperement and agressive behaviour.  The breed is banned in many countries for obvious reasons. Many families have reported fatal attacks.

7. Wolfdog


This dog is a hybrid between a german shepherd and a mountain wolf. That combination makes this type of dog very dangerous. They can act as perfectly protective dogs or completely wild beast depending on the situation. They are banned in countries such as Norway.

8. Bullmastiff


Keep your children away from this dog. In 2014 a Bullmastiff jumped over a fence and attacked two teenagers playing in the neighbours garden. It killed one of the boys and then went to attack it’s owner.

They are originally guard dogs and with their huge size, this is a dog breed that should definitely be treated with respect.

9. Huskies


A very popular dog due to their eyes. But it’s not just the eyes that makes them special, they are extremely good at pulling things for a long period of time. Huskies are used for sled pulling in the most arctic places in the world without getting tired. Huskies are usually safe if they are tame and alone, but even when they are fully tamed, you should never approach a flock of them as there have been several reported cases where they have randomly attacked their owner and killed him.

10. Doberman Pinschers

Doberman Pinschers

Because this dog is so strong and intelligent, it makes the perfect guard dog. It’s perfect as a family protection dog and is even used in the police to hunt criminals. However, if it’s not raised and tamed in the proper way, it could suddenly attack someone completely innocent. The Doberman Pinschers is perfectly capeable of killing a humans, as history unfortunately tells us. If you thought this dog was scary, hah!, keep reading.
