Is mass the same as great? Already on this list! If you’ve always wanted to know which dogs weigh the most pounds, then you’ve come to the right place. Big dogs, heavy dogs, gentle giants: these dog breeds are truly impressive!

In the dog world, there are true giants and numerous heavyweights. But basically, it is not just about the kilos – it is also important that they are well distributed on the body! Obesity in dogs is (similar to us humans) a major health risk and unfortunately also an increasing trend.

The situation is different, however, if the body size is correct in relation to the weight. That is why many of the heaviest dog breeds are also among the largest dogs in the world – and can therefore impress twice as much.

The following list should not be understood as a definitive evaluation of dog breeds, because of course there are always individual individuals of the bulkiest dogs that deviate from the norm – and would probably tolerate a diet well. Basically, males are usually larger and heavier than females.

That is why many of the weight specifications are designed for male representatives of these breeds. We have summarized some of the heaviest and largest dog breeds in the world for you – and added one or two places.

Some of these heavyweights weigh more than their owners. The following dog breeds are among the heaviest dogs in the world.

For some of these breeds, weight and size are important, for example when chasing fast game or earning respect as a guard dog.

Other dog breeds use their large, muscular bodies to pull heavy loads or even take down bears. Here are the most important details about the heaviest breeds.


The 31 Heaviest Dog Breeds Worldwide 61

The Mastiff is a large, bulky, and well-proportioned dog. Males reach a height at the withers of at least 80 cm.

The 31 Heaviest Dog Breeds Worldwide 62

The Boerboel (Afrikaans for “farm dog”) is a stocky farm dog of South Africa. This breed protects the farms from wild animals and cattle thieves.

These dogs are intelligent, trainable, and controllable. They exhibit strong protective behavior and respond to threats with confidence, calmly, and fearlessly.

Training and socialization for Boerboels should begin early, before the puppies develop too much dominance.

The Boerboel (Afrikaans for “farm dog” or “farm dog”; pronounced “Burbul”) originally comes from South Africa and was used as a guard dog. At that time, there was still little value in targeted breeding – the focus was on functionality. The mastiff-type dog should serve as a protector and guardian. In South Africa, the Boerboel was given a whole host of tasks. He was to take the children to the fields during the day, catch them a rabbit to eat at noon, and protect the house and yard in the evening.

In addition, whoever spoke of a Boerboel did not have the breed known today in mind. It was a term for a dog that did the work described. Only through selective breeding did the Boerboel that we know today become established.

Even today, his protective instincts are unrestrained and the breed needs its own territory, subject to its guarding skills.

If you are a novice dog, this dog breed is not ideal for you, as it requires a strong leader. The bond between Boerboel and the owner is very intense, but the dog must clearly recognize that the human remains supreme. Ideally, this dog breed is adopted as a puppy so that the animal grows up in the same environment and can mark out its environment and territory from the start. A change of home is often uncomfortable for the dog, as it bonds very strongly to a reference person, and even when moving to a new home, the Boerboel needs time to adapt to the change.

In order to enable this breed of dog to have an adequate and pleasant dog life, a large refuge is necessary for the animal. Problems could arise in the terraced house due to the strong protective instinct. A garden is great, but not suitable as a sole outlet. The dog has a strong urge to move, it should be exercised two to three hours a day. You should note that the Boerboel is not unfriendly, but attaches little importance to contact with other dogs. You should also never ignore the dog’s hunting instinct.

Quick Facts: With up to 91 kg, the Boerboel is the second heaviest dog breed in the world.

Thanks to his strong nerves, he remains calm in most situations. However, Leonberger should be brought up consistently. He is loyal to his people. He brings with him a sovereign composure and self-confidence. However, the Leonberger is not an uncomplicated beginner’s dog. If you want to get a Leonberger as your first dog, you should study the breed well and give the guard dog a loving upbringing. Sufficient exercise is important for the dog.

Leonbergers require a lot of grooming due to their long and thick coat. Daily brushing is a must to keep the coat from matting and remove the undercoat. The big dogs are not really suitable for the city, unless you have a large apartment and the opportunity to run around a lot. In principle, however, a little house in the countryside is the better option for the “Leo”. In terms of fur, Leonbergers are suitable for kennel keeping, but the good-natured giants feel more comfortable with their pack.

It should be rather rare that a dog breed is bred for a city. Leonbergers are actually named after the town of Leonberg in what is now the state of Baden-Württemberg. At the end of 1830/beginning of 1840, the city councilor Heinrich Essig is said to have crossed his Newfoundland bitch with a St. Bernard male. Later, a Pyrenean mountain dog and another St. Bernard were crossed. Actually, Essig wanted to breed the heraldic animal of his hometown, the lion, as a dog breed. The enterprising town councilor is said to have had success with the mane dog in his day and to have supplied some gentlemen with animals from his breeding. Essig was bred from non-pedigree Leonberger cattle dogs. By the way, Essig bred not only golden Leonbergers, but also white and silver dogs of this breed, which had a dark mane. The first Leonberger was born in 1846. As an adult, he weighed 160 pounds and was 80 cm tall. According to tradition, the dog had the mind of an angel. But it took a while before the breed was recognized. Envy spread among many breeders, because Essig is said to have even sold his dogs in palaces. Nobody less than Empress Sisi Leonberger is said to have bought it. Napoleon and the Italian King Umberto are also said to have been among Essig’s customers.

During the two world wars, the Leonberger breed almost died out. Nobody needed the big, good-natured dogs anymore. It is thanks to the commitment of a few breeders that the Leonbergers still exist today. Today the Leonberger has developed into an excellent family dog. However, he is one of the rather rare breeds – but with an increasing tendency.

The appearance of the Leonberger was established in 1895, but revised in 1938 and 1955. The current standard was defined in 1995. Incidentally, on June 10, 1948, the German Club for Leonberger Dogs e.V. was founded.

Caucasian Shepherd Dog

The 31 Heaviest Dog Breeds Worldwide 90

Up to 100 kilograms

The Caucasian Ovcharka (Russian: Кавказская овчарка) is a particularly resilient livestock guardian dog. That’s why these robust dogs need a lot of exercise in the great outdoors, even in wind and weather. Adult males can weigh up to 100 kilograms.

Caucasian Shepherd Dogs are medium to large-sized dogs with a strong to coarse build; they are sharp by nature and suspicious of strangers. These features, plus their endurance, undemanding nature and ability to adapt to a wide variety of weather conditions, give the opportunity to use Caucasian Shepherd Dogs in almost all climatic regions of the Soviet Union.

Caucasian shepherds are most widespread in the Georgian, Armenian, and Azerbaijan Union Republics, in the autonomous republics of Kabardino-Balkaria, Dagestan, and Kalmykia, as well as in the steppes of the North Caucasus, and in the Astrakhan region.

In the Transcaucasian areas, the dogs are usually more massive, in the steppe areas, on the other hand, they are lighter, longer-legged, and often even short-haired. Strong, well-balanced, calm personality with a well-developed defensive response that is expressed in an active form.

The Caucasian Ovcharka is typically characterized by both loyalty to family and fearlessness and intrepidity towards strangers.

Within the family, the Caucasian Ovcharka is extremely affectionate and sensitive. This behavior changes abruptly towards unknown persons, especially when threatened. Since the Caucasian Ovcharka has an innate sharpness, he is reserved and suspicious of strangers. This innate guarding and protective instinct can quickly get out of control if the owner deliberately encourages the protective instinct, e.g. at a dog park. Then a Caucasian can become a danger to humans.

Since the Caucasian Ovcharka are not generally barkers but are alert guards, they will reliably bark if anything is noticed at the door or on the property. One should accept this trait, since the dog was bred for this purpose, among other things.

The property should be fenced in, as the Caucasian Ovcharka also considers the adjacent area to be its territory and therefore also guards it.

In the family, the Caucasian Ovcharka is nice and has a pleasant personality. He is a strong, balanced and calm dog. A Caucasian Ovcharka wants and should be a friend and family member in equal measure, which of course does not exclude a loving, consistent upbringing, but rather requires it. However, its independent nature should never be restricted too much.

The urge to move of a Caucasian Ovcharka is to be regarded as rather low in relation to other “typical” working dogs. According to the breed description in the breed standard, his typical gait is a short trot, which turns into a somewhat clumsy gallop when he accelerates. In connection with the family, he likes to exercise, but is not suitable for hours of cycling training, for example.

English Mastiff

The 31 Heaviest Dog Breeds Worldwide 91
English Mastiff

Up to 100 kilograms

Despite its imposing appearance, this dog breed is the epitome of a gentle giant. In their nature, English Mastiffs are well-balanced resting poles that usually tend to shy away from excitement and action. While the females of the English Mastiff weigh a relatively “slender” 55 to 75 kilograms, males even reach up to 100 kilograms. Both are between 70 and 91 centimeters high.

The Mastiff – also known as the Old English Mastiff or Great Dane – originated in England and is one of the largest dogs of all.

It is considered the original breed of many large dog breeds, such as St. Bernard, the Newfoundland or the Great Dane. Today, this breed is rarely seen except in England.

Mastiffs are by no means as dangerous as they look, even though they are listed dogs in many federal states. They were once kept as war dogs or used to hunt bears. As a result, they used to have a stronger aggressive potential. Today, on the other hand, the mastiff has a particularly high stimulus threshold and hardly shows any combative traits.

In ancient times, imposing animals were mainly used as war and protection dogs. From the Middle Ages, their purpose was to be companion and protection dogs, as well as a hunting dog on big game hunts for the nobility. However, the origin of the Mastiff cannot be clarified with absolute certainty. There are several theories: Shaw and Beckmann, for example, claimed at the end of the 19th century that the English mastiff descended from the Tibetan mastiff, the Do Khyi, while others put forward the thesis that the mastiff developed completely naturally, i.e. without further crossbreeding.

Then there are hypotheses that he is a descendant of the Molosser dogs from Epirus and Macedonia who came to England on merchant ships. The name “mastiff” first appeared in the late 14th century. There is evidence that Mastiffs were used in a variety of ways: the first reports of their use to hunt bulls, wild boar and bears go back as far as the year 1050. Here, for example, there is talk of “a fight between a bear and six bear dogs”.

In general, fights between captured large animals and massive dogs for the amusement and entertainment of the nobility were the order of the day. In the 16th century, a purpose-built arena was built near London, where the popular “Bear and Bullbaiting” took place. The brutal fighting was also supported and financed by the British royal family.

The first solid evidence that the massive dog was also bred and used as a “war dog” dates back to the late Middle Ages. One of the lore tells of the Battle of Azincourt in 1415, where one of the massive dogs on the battlefield protected his wounded master.

Official pure breeding of the dog only began between 1820 and 1835.
