#10. The Chow-Chow

The Chow-Chow comes in at number 10. The males usually weigh between 60-80lbs and come stacked with a ton of fur and thick hair, hence the reason they are also called the Puffy Lion Dog. These dogs are just naturally mean and usually only stick to one dominant owner, and if one isn’t present, they will attack anyone they don’t feel comfortable around, which is usually everyone.
#9. The Rottweiler

The Rotweiler is a very powerful and strong physical dog, and like many other breeds, if this type of dog isn’t socialized and trained properly, it will become extremely aggressive and mean. The males weight ranges from 70lbs-130lbs, depending on the genetics of the dog of course. They were originally bred for herding, but due to stamina issues they were phased out and kept as guard dogs due to their large jaws and bodies.
#8. Cane Corso

The Cane Corso is a relative of the Neapolitan Mastiff. These dogs are extremely bulky, weighing between 80-110lbs. Originally they were bred during the Roman Empire as War Dogs, and the most distinct thing about these dogs is the gigantic head. They require a very dominant owner and should be socialized as soon as possible and as much as possible. If they are treated poorly, all hell will break loose.
#7. The Tosu Inu

The Tosu Inu is a Japanese breed that comes from such breeds as the Mastiff and Bull Terrier. They are fighting dogs – although not what you’d expect from such a large breed. When these dogs fight, they are expected to fight silently without barking, growling or whimpering. Get this, they are illegal to own in Denmark, Malta, Norway and other countries.
#6. The Caucasian Ovcharka

The infamous Russian prison guard dog. The Caucasian Ovcharka weighs between 100-160lbs. These dogs looks extremely massive due to their extremely thick fur coat built and bred for harsh cold winter conditions. The toughest prison in Russia, where the baddest of the bad go, is exactly what these dogs help guard. Even the craziest of inmates would think twice about trying to escape with a pack of Caucasian Ovcharkas just waiting to pounce.
#5. The Pitbull

Ahhh, the famous Pitbull. I’m sure you have read stories of a pitbull eating a child, or dismembering a human being for absolutely no reason at all. If raised properly, these dogs are harmless, but something in their genetic code gives them a knack to just attack and destroy anything that annoys them. They are built like brick shithouses, very low center of gravity, shortest dog in this list, but at the same time, they are the most muscular. Their jaw is extremely poweful and if it latches on, goodluck.
#4. The German Shepherd

The German Shepherd is one of the smallest dogs in our list weighing between 60-90lbs, but don’t let the small size compared to the other dogs in the list fool you. This is the smartest dog in the list, with great agility and powerful jaws it makes one great family gaurd dog. Also known as just “The Shepherd,” this breed is used commonly in police forces around the world to sniff out drugs and help track down escaped convicts. They also help the disabled due to their loyal companionship and ability to learn so quickly.
#3. The Doberman Pinscher

The Doberman Pinscher, also referred to as the 80s dog, or the Junk Yard Dog. Reason for these names is because this dog became famous in the 1980s and was used very often to guard junk yards from would be theives. Weighing between 80-130lbs, the “Doberman” is a taller breed with thin legs but a very stalky body and neck. These dogs are extremely agile and their endurance is the highest in this list. Occasionally the Doberman is used for police force purposes, and is also highly intelligent, right behind the German Shepherd.
#2. The Wolf Hybrid

The Wolf Hybrid is an extremely rare dog, but they do in fact exist. It is a mix between usually a wild Grey Wolf and a large breed dog, such as a Mastiff or Alaskan Malamute. The weight depends greatly on the mix, but usually it’s between 100-180lbs. Due to being half-wolf, this dog is very untrustable. It could turn on you at a moments notice, and dealing with the speed of a wolf and the power of a mastiff, you would be crazy to try and own one. They are usually extremely shy and timid towards humans, often running away, but if panic is caused, they will attack and aim for a major artery such as the jugular.
#1. The Cordoba Fighting Dog

The Cordoba Fighting Dog. Holy. Shit. This dog is so insanely crazy, that it went extinct, because it would rather fight than mate, no matter what breed. It just wouldn’t mate, it would literally fight rather than have sex. These dogs were bred obviously, for one thing, fighting. They couldn’t even hunt in packs or stay around other dogs because a fight to the death of one of the dogs would immediately break out. The only way to mate the dog was to basically force it. They weren’t the biggest, the strongest or the fastest, but they were by far the meanest dogs ever created. The Cordoba Fighting Dog didn’t take shit from anyone or anything, it would fight a honey badger any day of the week instead of getting laid.
