Meet the world’s strongest transport dog, the Alaskan Malamute. Descended from the Inupiat breed of dogs in Western Alaska, breeders developed him to carry heavy freight. He has a soft, but oily undercoat and a coarse outer coat to keep him warm in freezing cold temperatures.

This dog is vicious when provoked. A story in the Sydney Morning Herald surrounds a girl who lost a hand after a Malamute bit it off.

This hardy working dog is an indispensable companion once you control its aggression. Give him a job to do. Let him cart your groceries home. Remember that he has almost unending endurance, so it is important to have many activities planned for him. He may turn your house upside down otherwise.

22. Saint Bernard

Generally, saint bernards have good temperament.

Another working dog, the St Bernard, is an angel in times of trouble. Used for Alpine rescue, this Swiss dog is well-known for his gigantic size.

Having been bred for hunting purposes, the super sized dog has a powerful jaw. The Telegraph shares that a Saint Bernard bit a five-year-old, breaking her collarbone.

The St Bernard suits Suburban living. As expected, he loves a good romp in the snow. Keep his fierceness under control with lots of snow-based activities.

23. Boerboel

Boerboel is a task oriented dog. With proper training he can be a useful dog

The Boerboel, or South African Mastiff, is the dog you should have if you have property to defend. Breeders conjured this brindle-colored dog to defend homesteads in South AfrIca

A boerboel has a vile bite. Mandia Kunene, a postal worker who was delivering his daily quota of letters, suffered a traumatic attack by three of them. They are on alert almost 24 hours a day. Jackson, a Boerboel, passes his test as a guard dog.

A Boerboel has a balanced temperament that is very attractive. He instinctively knows who, when and what to attack, which makes training him a breeze. Gentle around children, he makes an excellent family pet.

24. American Bulldog

From the line of bulldogs that American migrant workers brought with them, the American bulldog served to guard farms and catch large animals during hunts. Stocky, this brown and white dog has strong muscles.

A bite from an American Bulldog is devastating. A breeder, who lost his arm after his bulldogs attacked him, received a prison sentence because his remaining animals attacked others.

When untrained, the American Bulldog is a terror. The Miami Dog Whisperer helps a bulldog with no social skills out.

Make sure that you introduce your American Bulldog to people from an early age. An active dog, he needs a twice-daily ration of vigorous exercise. He suits families that enjoy outdoor activities, such as trekking.

25. Neapolitan Mastiff

The Neapolitan Mastiff has unmatched courage. Used to fight people, elephants and other animals in battle, this dog is the quintessential war dog. When the breed neared extinction after World War 2, Premier Piero Scanziani set up a breeding kennel to guarantee its survival.

This dog is definitely susceptible to aggression. The Daily Mail shares a story of Dobo, a Neaopolitan Mastiff likened to the elf in the Harry Potter series of films. One bit a woman to death, nearly earning a jail term for his owner, Alex Blackburn-Smith. Law enforcement agencies worldwide use these dogs for protection.

Consider your readiness to own this dog carefully. Unless given obedience training, his fighting spirit is likely to show itself. With proper social training, he interacts well with people and other pets. He will humor children as well.

26. Fila Brasileiro

Welcome another member of the mastiff family, the Fila Brasileiro. This dog, developed in Brazil, served as a hunting, shepherd and guard dog. He still plays these roles.

This fellow is a unique blend of a Rafeiro do Alentejo, bloodhound and bulldog. His hunting style is as unique as he is. When he spots a prey, he waits for his owner to come and claim it instead of catching it himself. He is capable of showing extreme fierceness, especially when his family or territory is under threat. Out-of-control dogs, including the Fila Brasileiro, attacked a 14-year-old girl in Wigan. When well-honed, his protection skills come in handy. In this video, the Fila Brasileiro practices them in a controlled situation.

This dog does not need anyone to prompt him to show his ferocity, so make sure that you give him strict obedience training. Like other dogs, he will bond with you and protect you in times of need. Owners suggest that this dog, more than any other breed, loves his possessions and hates anything that threatens them. Separate him from children and young animals.

27. The Moscow Watchdog

A cross between the Saint Bernard, Caucasian Shepherd and the Caucasian Ovcharka, the Moscow watchdog resembles a big bear. Known affectionately as the Giant Protector, breeders in the Soviet Union created him for military guard duty.

He may look sweet and cuddly, but his sheer size and agility make him a force to reckon with. He tears off his trainer’s brace in a controlled attack situation.

Take the Moscow Watchdog home if you want a dog with a strong pack mentality. He will gravitate to you and your loved ones quickly, as your family will become his pack. So saying, he will guard you with his life. He will stay submissive to you, but do remember to set house rules lest his protective traits show themselves in destruction.

28. Newfoundland

Another war dog that makes lists of dangerous dogs regularly is the Newfoundland. Tough and diligent, this mastiff plays many working roles. Using his extensive capabilities, he served as a watchdog, war dog and even as a star attraction in a circus. One famous Newfoundland accompanied adventurers Lewis and Clark on their expeditions.

The Newfoundland has warlike traits like many mastiffs, and does show them when he is out of control. Two mastiffs, Chum and Champ, avoided euthanasia after attacking a Jack Russell in the neighborhood.

 Of course, he performs superbly during protection training.

A Newfoundland will make a wonderful addition to your family, because your loved ones will value his steady temper. Intelligent, he needs mental stimulation. Hone his working dog traits by giving him jobs around he home to do. He will love to guard your belongings or wake your children up.

29. Dalmatians

dalmatian are generally sociable but do not be deceived

You will associate the Dalmatian with the popular Disney movie series immediately.

It is difficult to miss his charming, liver-spotted coat.He hails from the Croatian region of Dalmatia, where he served as a border guard. Today, he is a popular family pet.

This does not mean that he has forgotten his war ancestry. In 2003, a Dalmatian attacked 2-year-old Niamh Smith. He scratched her eye, nose and throat. The wounds, of course, needed stitching. Dalmatians of old played a crucial role as firehouse dogs, often defending carriages carrying firefighters. Two would run with the coach, on either side. It still serves as a firehouse dog today. Meet Wilshire, the fire dog that teaches children about fire safety.

The 101 Dalmatians movies may have convinced you to get a Dalmatian as a pet. Do remember that he needs a lot of training. He flourishes if his owners have even temperaments. Exercise him regularly, as he is well-known for his destructive tendencies.

30. Bandog

The Bandog, born of various cross breeds, refers to a large-sized dog that home owners in Europe and America used as a guardian. He owes his name “bandog” to the chain he was bound to during the day, This dog, muscular and with a broad skull, guards homes faithfully today.

He is a vicious guardian, when provoked. The Bandog is a reliable Protection Dog. Watch how he refuses to let go of his “intruder” during a training session.He exhausts his trainer out completely.

This dog has a stable temper, and usually defers to his owner. If he receives proper social training, he is a hit with children. Stay aware of his strong defence, prey and hunting drives. Separate him from other animals and young children until you manage to teach him basic obedience.

31. Dogue De Bordeaux

Dogue De Bordeaux can be aggressive and protective of their owners

The elegant-sounding Dogue De Bordeaux, or French Mastiff, is a regular working dog, Bred in the Bordeaux region since the 14th century, he plays many working roles. Farmers use him to cart produce and heavy materials.

As gracious as he sounds, this fellow has a nasty nip. He ranks among banned dogs in some municipalities in the United States . He is an excellent attack dog, as this video shows.

This dog is not blindly obedient, so make sure that you develop a close rapport with him if you decide to take him home. Make sure that the laws in your region do not restrict you from owning. him. He is suspicious of strangers, so introduce him to your friends early. Harness his working dog inclinations, and get him to do jobs, like carting loads, for you.

32. Bully Kutta

The black-and-white coated Bully Kutta, or Indian Anglu Mastiff, is probably the most used guard dog in Pakistan. His origin is not well-known, but many experts suggest that he developed after British soldiers bred the mastiffs they brought with native Indian breeds.

Of the members of he mastiff family, the Bully Kutta is the most surly. His guardian instincts are strong. His small, but sharp ears stand erect when intruders approach. He makes an ideal Protection Dog.

Being the most dominant of the mastiff breeds, the Bully Kutta is not good with children. Make sure that you induct him in social situations and do not expose small animals to him.

33. The American Pit Bull

Pitbull training can be rewarding

These dogs are the Mike Tysons in the dog world. Fierce, aggressive and always making headlines for the wrong reasons. Due to their natural tenacity and endurance, many people abuse these traits by training them to be fighting dogs. This practice has led to the negative impression that all pit bulls are aggressive. But not pit bulls are aggressive. Cesar Millan has a very friendly and balanced pit bull on his show “The Dog Whisperer”.

Nonethless, there are documented attacks of pit bulls on children, the elderly and their owners. Pitbulls should never be provoked or taunted. They pack a strong bite. Once they bite, its hard to make them let go. And in this article, an 18 mth old baby is killed by the family pet, a pitbull.

Never leave a young baby or child alone with the pitbull. You are just asking for the unthinkable to happen if you do so.

Here you go, a comprehensive list of dogs breeds that can pose a danger to your family. But we believe that they will not be aggressive if given the proper training and guidance.

These most dangerous dogs, like all others, need an owner’s patient care. Stay attuned to their needs, and they will make wonderful companions.

    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!

    Felt a bit disappointed to see the Bullmastif as third on the list. My Bullmastif Tommy is my registered Assistance dog!!!

    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.

  • December 16, 2017 at 6:26 am

    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.
