Top 15 Most Aggressive Dog Breeds
It seems like you’re looking for information on the most aggressive dog breeds in various contexts. There is a lot of misinformation out there about the aggression of particular breeds. A dog’s inclination toward aggression depends on a wide array of factors, including whether they’re in pain or suffering from a lack of physical and mental stimulation, a victim of previous trauma at the hands of irresponsible or abusive owners, neutered or intact, or carrying certain genetics. While I can’t provide an exhaustive list, here are some breeds that are sometimes considered more prone to aggression, though it’s important to remember that individual temperament can vary widely within a breed:
Pit Bull Terrier
The pit bull is a medium-sized breed of dog that was originally bred to be used as a fighting dog. It has short hair and an athletic build, but it’s also one of the most popular pet breeds in America today because people love its gentle temperament!
Pit bulls are known for their spirited nature so they need plenty of exercise every day or else they’ll become bored and destructive inside your home. They also tend to be territorial and aggressive towards other dogs, so socialization is important for this breed.
Rottweiler
This is how they’ve been bred. Their heritage is in protecting livestock. Rotties are classified in the working group, and without a job, they can become bored, destructive, and aggressive. Because of their brute strength – they can weigh up to 135 lbs. – many people take advantage of them and train them to attack.
Rottweilers make affectionate pets that can get along with other animals in the home, but they can get highly aggressive when protecting their family members if they have not been appropriately trained. Rotties are also used in the illicit dog fighting industry, where they are trained to be aggressive.
German Shepherd
German shepherds frequently serve as police or military dogs, but not because of their aggressiveness. Instead, it’s because they respond well to training. German shepherd owners can use this to their advantage and train their dogs to behave well. They are extremely intelligent, highly trainable, and athletic dogs. Their medium to large size and above-average strength makes them formidable opponents for intruders. These dogs also have very strong jaws; their bite is strong enough to break bones. It’s no surprise that an aggressive German Shepherd could pose a real danger.
Chow Chow
The Chow Chow is also considered one of the most aggressive dog breeds in the world. Distinctive and extremely independent, the Chow Chow breed requires a lot of attention as well as proper and regular training. They are known as one of the most aggressive dog breeds, which means that recorded bites are higher for this breed than for many others. Chow Chows also require a lot of exercise or can become unpredictable, aggressive, and dangerous. Chow chows sure are cute with their squashed faces, furry manes, and fluffy double coats. They’re also often unsociable and stubborn. These Chinese dogs often bond with just one person, and they can become possessive.
Akita
Their strong prey drive will also have them pouncing on wildlife, so be careful with other animals in the home. The remedy is proper training and socialization at a young age. When you place a potentially aggressive dog around other animals as a puppy, they begin to build connections that can overpower hunting instincts. They learn that not all animals are made to be hunted.
Their loyalty to guardians is almost unmatched. The most famous Akita, Hachiko, held a vigil at a train station for years, where he previously met his guardian after his owner died. That’s some powerful loyalty.
Alaskan Malamute
Alaskan Malamutes are snappy dogs that can bite without warning. They are also known for being very aggressive and territorial. Alaskan Malamutes are strong dogs that were originally bred for sledding. They are still used for this purpose in some parts of the world, but they have also become popular as pets.
Malamutes are loyal and affectionate with their families, but they can be aggressive toward other dogs and strangers. They need a lot of exercise and space to run, and they should not be left alone for long periods. Malamutes are not good candidates for apartments or small homes.
Siberian Husky
Siberian Huskies are caring, and docile dogs, but their aggression issues are mainly territorial and linked to poor training. They are high-energy dogs, and first-time owners may find it difficult to manage and train them. If they are kept locked all day, anxiety and stress develop, leading to uncalled aggression. This breed is famous for its stubbornness and dominance hence is very difficult to control and a pet parent needs to keep them busy at all times. These large working dogs are very active and need physical stimulation, and they have high prey drives. They’re also a little wild and can be unpredictable. Ownership comes with a responsibility—you must socialize them early and keep them away from small children, or they may unintentionally be too rough.
Bullmastiff
These dogs are seriously large. They’re huge. They average in size between 100 and 130 pounds. No matter what attitude they’re exhibiting, they make for an imposing form.
They’re bred with a guarding instinct but are an easy breed to train and socialize. Taking them out for regular walks can help curb potential bad behavior and early socialization for puppies should ensure they don’t guard you aggressively.
Paradoxically, given their enormous size, Bullmastiffs are excellent apartment dogs in many ways. They’re generally quite lazy and lethargic so they do better with smaller spaces and fewer walks than many other breeds.
Boxer
They can be wonderful family pets if their owner has had previous dog-handling experience and can dedicate time and effort to training. But without this, they can be boisterous, dominant, and aggressive, meaning they can be a danger to people.
This breed is known to be extremely affectionate towards the family it lives with, and seeing this well-loved breed on a list with other dangerous breeds may come as a shock. But it is not recommended to pick this dog breed if you have never owned a dog before.
Dalmatian
The Dalmatian is a medium-sized dog in the working group that ranges in size from 45 to 60 pounds. Predominantly these dogs have a short, dense, glossy coat that is white with either black or brown spots. The exact origin of the Dalmatian is not known. This breed is been used as a carriage, guarding as well as cargo dog, since the late 18th century. The Dalmatians are very reserved with other dogs and hence need to be socialized right from the puppy stage. They are child-friendly but are seen to develop some behavioral issues if enough attention is not given by their master. These energetic dogs need a good place to release some of their energy.
Presa Canario
Originating from the Canary Islands, Presas Canarios were bred for working livestock. Their powerful build combined with a sharp instinct makes them effective guardians. They can be very dominant and require a handler who understands canine behaviors and can establish themselves as the pack leader.
With proper training and socialization, they can be calm and affectionate companions. However, due to their strong guarding instincts and potential for aggressive behavior if not correctly raised, they are not recommended for first-time dog owners.
Dogo Argentino
Dogo Argentino is territorial, aggressive towards other dogs, and also at risk for developing hip dysplasia. They might not be the best breed for pet owners who live in apartments or have busy schedules. They’re also extremely protective of their pack which makes them great guard dogs! The Dogo Argentino is a massive, white, muscular dog bred in Argentina, mainly for big-game hunting. The hunting involved puma and boar hunting. Just imagine the strength and level of danger the breed can pose to the victim. These dogs are extremely athletic and strong. It was bred to be a non-aggressive species towards humans.
Doberman Pinscher
Doberman Pinscher is known to be one of the most aggressive dog breeds in the world today. The Doberman Pinscher is a very loyal and alert dog breed that is known to be one of the best guard dogs around today. They attack only when provoked and are quite aggressive towards other dogs and strangers.
The Doberman Pinscher is a medium-sized working group dog that ranges from 70 to 90 pounds and has a thick, glossy, short-haired coat that comes in red, black, blue, or fawn colors. This medium-sized breed is very intelligent and to date is used mainly as guard dogs and for police work.
Staffordshire Bull Terrier
The British cousin to our American mentioned above, the Staffordshire Bull Terrier, also affectionately known as the Staffy, this dog has a reputation that doesn’t seem to fit the bill. Fearless, loyal, energetic, and strong-willed, all this dog needs is a lot of stimulation, training, and early socialization to keep him out of trouble. Nevertheless, it’s still one of the breeds to watch out for.
The only thing that makes this one of the most dangerous dogs is that it doesn’t like other dogs very much, but they are good with kids.
Great Dane
The Great Dane is another breed, that may instill fear in some people due to its large size, but is beloved by many, who discovered how affectionate and gentle these dogs are. They develop a strong bond with their owners and get along with children, which makes them great companions and family dogs. They can also cooperate with other dogs, especially if raised together. You may want to train your lovely paw giant some basic manners, as due to their size they may be a little uncoordinated, especially in small apartments. The level of energy of this breed, similar to other large breeds, is rather low. They may be more energetic during their puppy phase, but adult dogs are rather calm and a bit lazy.
