33 Top Most Dangerous Dogs List – Fierce and Aggressive Dogs

11. Chow Chow

The Chow Chow, a Chinese breed, looks adorable and fluffy, but do not let his looks fool you. Approaching him when he is in a bad mood can lead to disastrous consequences.

Chow chow should be trained on how to behave

From North China, this “Fluffy Lion Dog” has this moniker for obvious reasons. Apart from having a thick coat that resembles a mane, he behaves like a lion. According to the Lijegren Law Group, out of 238 deaths from dog bites from 1979 to 1998, Chow Chows caused eight.

Aggressive inclinations are most common in the Chow Chow. Protective of his family, he will not willingly let strangers into their midst. He lives peacefully with other dogs, but of the opposite sex. Never unleash your Chow Chow, because he may attack nearby animals or people on a whim.

To curb aggression, give your Chow Chow work to do. Many Chow Chows serve as protection and surprisingly, therapy dogs as well.

12. Wolf-Dog Mixes

wolf dogs are unpredictable and can flick the aggression switch all of a sudden

The WolfDog, a cross between wolves and domestic dogs like the Spitz, German Shepherd and quite surprisingly, the poodle, is a popular hybrid.

He is as fearsome as he sounds. Some Wolfdogs, unable to keep their wild natures in check, have attacked their owners. Sandra L. Piovesan, who owned a pack of wolf dogs, died after they turned against her. Vets euthanized the animals after her death.

Having an unpredictable nature, the Wolfdog cannot live in an apartment. He is destructive and relatively difficult to introduce to other dogs. Being part wolf, he is wary of strangers and needs the hand of an experienced owner. And even so, they can turn against the owner for no particular reason. So be careful, they are really dangerous.

13. Siberian Husky

never leave a child alone with a siberian husky

You may imagine two lines of Siberian Huskies pulling their tired owner on his sled. This handsome working dog, originating from Siberia, is from the Spitz family, His thick, double-coat has distinctive markings.

Without proper training, a husky is dangerous if left alone with a child. The Fradettes, who left their female husky, Spot, alone with their baby, came home to a tragedy. Spot, who had escaped from the basement where they had locked her, had delivered a fatal bite to their baby’s head. She had apparently tried to comfort the baby, who was crying.

Huskies are naturally joyful, excitable and easy to train, if you start doing so early. Check any aggressive behavior by giving him a job to do. Diligent and loyal, he will tote your groceries in a small knapsack for you. Introduce him to social situations when possible.

14. Akita

Akita must be trained at a young age to prevent aggression

Hailing from Northern Japan, the Akita was originally bred for hunting deer. With his brown-and-white coat, he is graceful and handsome.

He is also fierce. In July 2015, Kayleigh Gallacher received an unpleasant dose of trauma when she tried to pet a Japanese Akita. The dog, mistaking her action as a threat, bit her arm to the bone. Despite this, Kayleigh plead with authorities for his life.

If you are an Akita owner, note that two Akitas of the same gender should never live together. An Akita can live with other animals, if they do nothing to push him too far. To prevent fights, separate your Akita from other animals during mealtimes. Make sure that he receives behavioral and social training early. Bring him to dog runs as often as you can. This is an example of how an Akita can blend with other dogs if you do this often enough.

15. Staffordshire Bull Terrier

The Staffordshire Bull Terrier, or Staffie, has Pitbull Ancestry. Such dogs were often used in dog fights, though this is illegal in many countries. The Staffordshire Kennel Club established the breed standard for the dog in 1835.

A Staffie is stocky, muscular and has sharp incisors that can grind. Mayzee Jo Gespa, a toddler attacked by a Staffie, needed 240 stitches after one attacked her face.

Staffies are highly energetic, and love physical activities. Letting him experience them will curb his aggressive nature. Separate him from other animals, because he may show dominance towards them. He is charming if trained.

16. Boxer

Developed in Germany, the Boxer, with his square, firm head, is regal. Hunters in the 19th century employed him to catch bear, deer and boar.

Boxers have history of vicious attacks on humans

To prey, the Boxer’s face is the face of terror. He has a strong bite, which he will hold until told to release. Police in Scotland killed a Boxer after it attacked a father and his two children. If you want a dog that deters people effectively, take a Boxer puppy home. His stern expression will scare any intruder. That said, he mixes well with people if you start introducing him to them early. Note that he is lively and needs constant exercise. To check any aggression, bring him on jogs.

17. Rhodesian Ridgeback

A dog breed developed in Zimbabwe, Southern Africa, the Rhodesian Ridgeback offers protection to the homes of the Khoikhoi people. They tapped on his hunting abilities.

Described as lean, muscular and ugly, the brown Rhodesian Ridgeback sounds like a member of the Dog Mafia. He is certainly not tame. An owner of a Ridgeback after his dog attacked a school boy in Cardiff.

This dog needs mental stimulation and exercise. He becomes frustrated and may bear his teeth if he does not receive it. Watch how a trainer manages to leash train a Rhodesian Ridgeback that tries to attack anything that moves.

18. Caucasian Ovcharka

Descended from Caucasian Mountain Dogs, the Caucasian Ovcharka makes a Russian farmer’s life easier. This working dog helps famers to gather their livestock. The breed is especially popular in Georgia.

Of the Molossan bulldog variety, this dog has a strong jaw. His thick coat protects him from the cold. This fellow can hold his own against wolves, and has killed two of them. Law enforcement agencies play on his fearsome demeanor and use him as an attack dog.

The Caucasian Ovcharka is assertive and means business. He will take guard duty seriously, and is alert. He is suitable around older children Let him meet people and their dogs as often as possible, and you will curb his dominant nature. Exercise him often as well.

19. Pharoah Hound

The Pharoah Hound is a resident of the island of Malta. You may find his lean frame and pointed nose familiar, because he is often found on Egyptian murals. In Egyptian mythology, his form depicts the God Raa. The Egyptians valued him highly, and used him on hunting expeditions.

The Pharoah hound is a sight hound, and runs fast. This dog is dangerous around animals and young children, as his chasing instinct will kick in. He bonds with people quickly, but do not take him off his leash when on walks.

20. Czechoslovakian Vlcak

dangerous when left alone with small children. Can flare up anytime

The Czechoslovakian Vlcak is the best of both wolf and dog worlds. He is the result of an experiment conducted in Czechoslovakia by breeders who wanted a dog that had the loyalty of a German Shepherd, and the strength of a Carpathian wolf.

Developed as an attack dog for the Czechoslovakian Military Special Forces, he has strong fighting instincts. He is now a valued member of the Russian Army, which trains him to attack perpetrators. His bite is so powerful that his trainer has to wear a metal brace on his wrist, underneath heavy padding, during training.

Note that this dog has strong hunting instincts as well. If you have small animals in the home, do keep them far away from him. To conquer his ferocity, stimulate him mentally. Make use of his senses and send him on food trails.

    There are some things about what people say. One of them is leaving a pit bull alone with a young child or baby. That is not going to provoke this animal to attack. I have lived with pit bulls my entire life. And not once did they attach me as a young child. My sister grew up with a pit bulls. She pushed on the dog and pulled on the dog. Not once did the pit bull bite nip attack my sister.

      That said, it’s still NOT a good idea to leave ANY dog with a young child or baby for that matter. Too many factors which might include the young child teasing the dog or the baby just crying it’s tiny lungs out could cause aggression in any dog. Not all pit bulls are designed the same as each has it’s personality so your sister was very lucky as some might just bit her as she pulled on it’s ear or tail too hard. We can’t LUMP all pits together! By leaving a dog (any type) ALONE with a child or a baby might provoke the animal so it’s easier to just lock the pit bull away. Then take the baby, toddler or young child away from the parent if left alone for ANY reason with no babysitter or parent in sight! Take it to the bank as I have a SINKING FEELING you’re childless so happy ’bout that k? Alo Ha!

    No dog, regardless of what breed, family pet or loyal friend should ever be left alone with children. You as their parent are their protectors and playmates. Please do not expect your dog to fulfil your parental duties. If more pictures were made available to the public of the horrific injuries made on children, I would like to think, we would all act more responsibly.

    • March 4, 2017 at 6:31 pm

      I wrote almost exactly the same thing Cheryl so CHEERS!! No Child ever nor a toddler not a baby should EVER be left alone at home by themselves much less with a dog of any breed. Too many times parents think they could dash out to the store for instance so what if the house burned down? Take your baby, toddler your young child with them to the store like I did as a single mother from birth. You made me laugh with your parental dog duties of raising a child huh? Really, Darwin’s Theory isn’t a theory! Thanks Cheryl. My nephew got bit my our family’s pit bull after teasing it in his 20’s so dogs of any breed should not be placed in a room with a young child, toddler or baby ever! It’s not the fault of the dog it’s the owner’s fault who is the parent also that is not much of one huh? Teasing or even crying their lit’l lungs out could trigger an attack even by the family pet so watch your children YOURSELF.

    Less than two weeks ago I was attacked by a vicious dog & bit several times…whether it’s pitbulls OR large vicious mix breed dogs, they all have teeth & can do serious injuries.
    I owned a beautiful girl pit bull named “Lexi Star” she never bit anyone BUT she was VERY protective over my 9 yr old son. I do believe IF someone had of hurt him she would of definately attacked for my son…her best friend.
    Some black man that I turned in for beating his 8 German Shephard, two had to be put to sleep for skull injuries, got out of jail & poisened our dear “Lexi Star”…RIP Lexi, we loved you dearly.
    You were my sons best friend…

    • March 4, 2017 at 6:37 pm

      I am so deeply saddened Cheryl M. for your tremendous loss of Lexi Star. RIP That’s tragic! OMG!! Very upset even in Hawaii most are cats that are poisoned or trapped then dumped which I lost five of ’em. I will be careful as I’m getting a NEW pit bull puppy with these Neighbors from Hell. I feel for you so the black man poisoned your pit bull after you complained? This is INSANE!! Such a huge loss for your young son & yourself my heart goes out to you Cheryl. I am DEPRESSED just reading your words & hope to God you have a TRO on this criminal to land him back in Jail. You lost your BFF along with your son’s BFF so terrible! After moving to Hawaii from Florida I can actually say I HATE the people in Kona, HI not Oahu. Mostly some locals & the Evil Spirits no Aloha Spirit older than dirt Cali. GEEZERS that trap & kill someone’s pets now up to 37+ of ’em. Humane Society Officer does NOTHING here in pair of dice so I pray to God they leave us alone with a Gotty (part) pit bull coming to the Big island of HI that won’t be so friendly!

    Pit bulls are UNPREDICTABLE.
    “Rescue” dogs are frequently emotionally unstable.
    As much as I feel for these abused animals,
    they will NOT be safe to adopt as pets for your family, even if very young.

    They have been selectively bred for hundreds of years to be tenacious and relentless killers.
    Many “loving and friendly” family pets have suddenly and WITHOUT WARNING
    turned on their owners and/or their children and other pets.
    Their style of holding on and mauling is much more damaging than that of other dogs
    (this also applies to the other “bully” breeds).

    This is a tragedy that humans have created through genetic selection.
    It cannot be undone by training or “rehabilitation”. Take care
    when around these animals, even if they appear to be very tame.
    They can be “triggered” – for no apparent reason – in an INSTANT.

    The amount of idiocy in these comments are insane.. You are talking about humans not dogs.. Ive been around tons of pits, germans etc.. Never have i ever had any of these bs comments talking about. I have plenty of friends and family that leave and have let their children home with the dogs just fine etc. You are responsible for teaching the dog as well as the child. Its very rare a dog attacks for no reason. Very rare normally due to something medically or the people dont want to admit they caused the problem. All the dogs ive been around you could push, pull, grab their ears etc. They didnt do anything because of responsible owners doing what they are supposed to do.

    Wasn’t Petey on Our Gang a Pit Bull? I’ve had many and I have always found them the most tolerant around people and kids. On the other hand, if a kid pulls and messes with a cocker spaniel they get nasty as well as other smaller breeds. Don’t think just size has to do with damage to a person or child.

  • February 6, 2018 at 8:40 pm

    There’s a lot of misleading information about the nature of these dogs. Nurture in this case is the deciding factor for aggressive behavior, not nature. It does not matter what animal you are, genetics works the same and attacking your family is not in genetics. Chihuahuas are a great example of how neglective training can lead to aggressive dogs, and I have had babies around the kindest dogs which were pit bulls and huskies. Of course, instinct is real but that will not determine how your dog WILL behave.

    I have owned several dogs, both purebred and curs. By far the best family dog we ever owned was a GSD/Standard poodle mix. He was brought into the family at 5 weeks due to his dam being killed after escaping her pen and being killed by a car. We went to pick up the puppy. My wife took a box to put him in. He would not fit the box, which was the best thing that could have happened. This was the first time he had been separated from his litter mates. She held him for over an hour on the way home, He imprinted on her, and was her guard dog. We had two children at home, five and three.. He never bit either of them, but he had them believing he would. He taught them respect for dogs, and no stranger could approach them without an introduction. During the day, if anyone was outside he would come to one of us adults and growl, but at night if there was a prowler, he would nudge one us awake and growl low. We always figured he did that so he would not alert them and he would not get a chance to bite them. He was fine with visitors if introduced, but watched them for any overt move. The dam of this dog was mild mannered, but the poodle was vicious. He was a guard dog at a car dealership, and a burglar made the mistake of trying to get in. Seventy some stitches later he got out of the emergency room. I was unsure about putting the pup with the kids. Those were his kids, and If they needed a spanking the dog had to be locked outside. He would come through a hollow core interior door.

    I disagree with the list. I wouldn’t leave a child unattended around any animal….but shepards ? COME ON….very loyal dogs. There are some really nasty canines out there. I’ve only been bitten by small yapper dogs. Once a chihuahua got me right in the face, ugh! The best thing you could do is get your dog trained. 🙂

  • September 22, 2018 at 10:36 am

    Fila brasileiro should be number 1 as it will attack anyone or animal he hasn’t met after 6 months of age

  • September 25, 2018 at 10:25 pm

    Ive had more small yappy dogs try to bite or nip than any of the large breeds. i’d trust an unknown larger breed dog over a chihuahua or pomeranian any day. I used to work in a shelter, most animals that came in were frightened and confused because all of a sudden they had thier family and home taken away from them. all needed an ajustment period to get used to the shelter. many a dog of cat are withdrawn and hiding in the cages, but take them outside on a leash, spend a little time with them, thier personality will start to show. By the way, the “pitbull” breeds were known as “nanny dogs” in the early 1900’s as they were good babysitters for children. “Petey” from the “Little Rascals” was a pittie.
