What Are the Biggest Dog Breeds? 25 Largest Dog Breeds

Do you love big dogs? Many people prefer larger dogs to smaller ones and if you are one of those people we have created a list of the ’25 biggest dog breeds’. We have included information on their history, temperament, characteristics and common health conditions.

Characteristics of the Biggest Dog Breeds in the World

The largest dog breeds in the world are surprisingly different when it comes to their characteristics and even their physical abilities and stature. Some big dogs are bred to hunt and guard while others are gentle giants that roll over when anyone comes in the room.

Many of the largest dog breeds in the world have been bred to perform jobs such as protecting farmers from wild animals or to hunt large animals. For this reason it is important to learn your dog breed’s history. If your dog’s breed was created to work all day, they are going to need more exercise than some other breeds.

Unfortunately, many large dog breeds have a short lifespan compared to smaller breeds. They also tend to have more health complications than their smaller counterparts and can be more costly to own.

Bigger dogs also tend to need more space than smaller canines, which means they may not be suitable for apartment living. They can also need more training as a misbehaving Great Dane is probably going to be a bigger problem than a badly behaved Boston Terrier.

The 25 Largest Dog Breeds in the World

Below we have listed the 25 biggest dog breeds in the world. We have included information on their history, characteristics and more. Note: we have ranked the breeds below based on their weight.

English Mastiff (54 – 113 kg)

This massive breed holds the record for the greatest weight ever recorded for a dog at 155.6 kg (343 lb). The record setting English Mastiff was known as Aicama Zorba, and he stood 94 cm (37 inches) at the shoulder and was 251 cm (8 ft 3 inches) from tip to tail.

English Mastiffs can trace their roots back to Roman times with part of their ancestry being the Pugnaces Britanniae (Dogs of Roman Britain). It is unsure when exactly the Pugnaces Britanniae breed came into existence, but some believe they were descended from dogs brought to Britain by the Phoenicians in the 6th century BC.

The Alaunt is likely to have been another contributor to the English Mastiff. Alaunts were introduced into Britain by the Normans. Over the course of centuries, the English Mastiff breed developed and they were primarily used as guard dogs.

English Mastiffs feature a massive body with an extremely broad head. They are the largest dogs in the world in terms of mass, although Irish Wolfhounds and Great Danes can be taller. Most male English Mastiffs tend to weigh between 68 to 113 kg (150 – 250 lb), while females tend to be 54 – 91 kg (120 – 200 lb). Heights are usually around 76 cm (30 inches) for males and 70 cm (27.5 inches) for females.

Despite their enormous size and appearance, English Mastiffs tend to be quite gentle and docile dogs. They are powerful and loyal, but due to their physical size they are not suited to city life.

It is extremely important that these dogs be fed well and exercised correctly. Excessive running for the first two years of an English Mastiff’s life is not recommend as it may damage the growth plates in the joints. The breed tends to suffer from hip dysplasia, gastric torsion, obesity and more.

English Mastiff Stats

• Male weight – 68 to 113 kg (150 to 250 lb)
• Male height – 76 cm (30 inches)
• Female weight – 54 to 91 kg (120 to 200 lb)
• Female height – 70 cm (27.5 inches)

Caucasian Shepherd Dog (45 – 100 kg)

The Caucasus Mountains are home to some of the oldest living dog breeds, such as the Azerbaijani Volkodav, Azerbaijani Shepherd Dog and Georgian Shepherd Dog. During the 20th century Soviet breeders selected some of these varieties and created the Caucasian Shepherd Dog.

The different varieties of Caucasian mountain dog have been used as hunters, guardians and shepherds for thousands of years. The traits of these dogs were passed onto the Caucasian Shepherd Dog and the breed is still used to protect livestock from predators.

Caucasian Shepherd Dogs are extremely muscular and strong boned. Plain Caucasian Shepherds have a shorter coat and appear taller as they are less strongly built, while Alpine types are more muscular with a heavier coat.

With an average weight of 50 – 100 kg (110 – 220 lb) for males and 45 – 80 kg (100 – 180 lb) for females, the Caucasian Shepherd Dog is one of the heaviest and largest dog breeds in the world. Males tend to stand 72 – 90 cm (28 – 35 inches) tall and females are usually 67 – 78 cm (26 – 31 inches).

Caucasian Shepherd Dogs are extremely independent, intelligent and fearless. They are highly protective of their territory, which makes them an excellent guard dog. Additionally, the breed can be aggressive towards other dogs, which means socialisation and obedience training is extremely important.

With a lifespan of 10 – 12 years, the Caucasian Shepherd Dog is a long-lived large breed of dog. They tend to be healthy dogs, however, hip dysplasia, obesity and heart disorders can be a problem.

Caucasian Shepherd Dog Stats

• Male weight – 50 to 100 kg (110 to 220 lb)
• Male height – 72 to 90 cm (28 to 35 inches)
• Female weight – 45 to 80 kg (100 to 180 lb)
• Female height – 67 to 78 cm (26 to 31 inches)

Tosa Inu (36 to 90 kg)

This breed of dog originates from Japan and was originally bred in Tosa, Shikoku (present day Kochi) as a fighting dog. They are considered to be rare and ownership in many countries is restricted as they are considered to be a dangerous breed.

Tosa Inus were first created in the second half of the 19th century. The breed started from the native Shikoku-Inu (an indigenous dog that weighs about 25 kg (45 lb). Breeders then cross the Shikoku-Inu with European dog breeds such as the Old English Bulldog and the English Mastiff. The aim of this was to create a larger, more powerful breed of dog.

Coats on Tosa Inus tend to be short and smooth, and are often red, brindle or fawn, but occasionally they can be dull black. The coats require very little maintenance.

Interestingly, Japanese breeders tend to focus on producing smaller dogs, while non-Japanese breeders focus on larger Tosa Inus. Japanese dogs tend to weigh between 36 to 61 kg (80 to 135 lb), while those from other countries are usually anywhere from 60 to 90 kg (130 to 200 lb). The larger foreign Tosa Inus tend to stand anywhere from 62 to 82 cm (24 to 32 inches) tall.

Tosa Inu Stats

• Japanese weight – 36 to 61 kg (80 to 135 lb)
• Non-Japanese weight – 60 to 90 kg (130 to 200 lb)
• Height – 62 to 82 cm (24 to 32 inches)

Tibetan Mastiff (55 – 90 kg)

The Tibetan Mastiff is not only one of the world’s largest dog breeds, it is also the world’s most expensive breed with one selling to a Chinese businessman for an eye-watering $1.5 million.

Tibetan Mastiffs are known as ‘Dogs-Khyi’ in Tibetan and they have been used to protect herds, flocks, tents, villages and more for thousands of years. They are traditionally allowed to run loose at night and they are known for their fierce loyalty.

Interestingly, the Tibetan Mastiff is not a true Mastiff and it gets its name from the Europeans who first came to the country. In Europe, almost all large breeds of dog were referred to as “mastiff”, so they carried on the tradition. In truth, the Tibetan Mastiff should really be called the Tibetan Mountain Dog or the Himalayan Mountain Dog.

There are essentially two types of Tibetan Mastiff: the first being the ­Do-khyi and the second being the Tsang-khyi. The Tsang-khyi is referred to as the “monastery” type and is generally taller, heavier and bigger boned. The Do-khyu is regarded as the “nomad” type and is typically used for more active jobs. Both types can be produced in the same litter.

Male Tibetan Mastiffs can reach heights of up to 83 cm (33 inches) and usually weigh between 55 – 90 kg (121 – 198 lb). In some cases, Tibetan Mastiffs can weigh in excess of 115 kg (254 lb), however, these are generally not used as working dogs as they would cost too much to feed.

The breed features a long double coat that can be found in a wide variety of colours, including solid black, black and tan, various shades of red and more. Tibetan Mastiffs also lack the unpleasant smell that affects many larger breeds of dog.

Like many large dog breeds, it is important to train and socialise Tibetan Mastiffs. They are incredibly intelligent and known for being somewhat aloof with strangers. Tibetan Mastiffs often sleep during the day and can be more active at night. They have a very loud, strong bark that means they should not be left outside at night.

Compared to many other larger dog breeds, Tibetan Mastiffs tend to have a longer life expectancy (breeders often claim 10 – 16 years). They tend to have fewer genetic health problems although Hypothyroidism is fairly common in the breed.

Tibetan Mastiff Stats

• Weight – 55 to 90kg (121 to 198 lb). In some cases they can exceed 115 kg (254 lb)
• Height – Up to 83 cm (33 inches)

Boerboel (55 to 90 kg)

This large, mastiff-type breed of dog originates from South Africa and is bred for the purpose of guarding homes and farms. They are one of the strongest and most powerful dog breeds in the world with a bite force of 800 psi.

It is generally believed that Boerboels were created from the interbreeding of native African landrace dogs, such as the Africanis, with breeds brought into South Africa by British, Dutch, and French settlers.

Boerboels are large with a very strong bone structure and well-developed muscles. They tend to have a blocky head, with a short length between the stop and nose. The coat is short and sleek with a dense coverage of hair. The recognised colours are brindle, fawn, brown and black.

Male Boerboels usually weigh between 65 to 90 kg (143 to 198 lb), while females are smaller at 55 to 70 kg (121 to 154 lb). Heights typically range from 60 to 77 cm (24 to 30 inches).

This is a highly intelligent and energetic breed. They are often called “Velcro” dogs, as they always want to be with their owners. While they tend to be good with children, Boerboels need firm training and good socialisation from a young age. The breed can be somewhat aggressive to other dogs.

Overall, Boerboels are healthy dogs but they can suffer from hip and/or elbow dysplasia. The average life expectancy is ten years for this breed.

Boerboel Stats

• Male weight – 65 to 90 kg (143 to 198 lb)
• Female weight – 55 to 70 kg (121 to 154 lb)

Bully Kuttas are working dogs that are primarily used for hunting and guarding purposes. They have also been kept as pets by ruling families in India and the surrounding region.

Male Bullys can weigh anywhere from 70 to 89 kg (154 to 196 lb), while females can be 60 to 70 kg (132 to 154 lb). Heights typically range from 76 to 86 cm (30 to 34 inches) for males and 75 to 80 cm (29.5 to 31.5 inches) for females.

This breed is often described as intelligent, alert, responsive and aggressive. They should only be owned by experienced dog owners and they need to be trained and socialised from a young age.

St. Bernard (54 – 82 kg)

The St. Bernard breed is an extremely large breed of a working dog that originates from the Western Alps in Italy and Switzerland. They were originally bred for rescue by the hospice of the Great St Bernard Pass on the Italian-Swiss border.

The hospice was built by and named after the Italian monk Bernard of Menthon. The earliest written recordings of the breed date back to 1707, while the first evidence that the dogs were used in the monastery date back to 1690 in paintings done by Italian artist Salvator Rosa.

The most famous St. Bernard at the hospice was a dog called Barry. According to reports, Barry saved somewhere between 40 and 100 lives during his service. There is a monument to Barry in the Cimetière des Chiens, and his body was preserved in the Natural History Museum in Berne.

St. Bernards can have either a smooth or rough coat. The smooth coat is usually close and flat, while the rough is dense, flat and more profuse around the neck and legs. Most dogs are typically a shade of red with white, or mahogany brindle with white. Black is also usually found on the face and ears.

Most St. Bernards weigh between 54 to 82 kg (120 to 180 lb) and they usually stand anywhere from 66 to 76 cm (26 to 30 inches) tall. However, the breed is known to get much larger. A St. Bernard by the name of Benedictine V Schwarzwald Hof reached a weight of 143 kg (315 lb), which made earned him a place in the 1981 edition of the Guinness Book of World Records.

Due to the incredibly fast growth rate of St. Bernards, it is incredible important to feed and exercise them properly, otherwise they can suffer from serious joint and bone problems. Hip and elbow dysplasia are common and Osteosarcoma (bone cancer) is hereditary. Most St. Bernards have a lifespan between 8 – 10 years.

These dogs are known as gentle giants and they tend to be very calm and patient with adults and children alike. They also tend to be very friendly with other dogs, but correct obedience and socialisation training is important.

Great Dane (50 – 82 kg)

In the 16th century, the nobility in many European countries imported strong, long-legged dogs from England. These dogs were descended from crossbreeds between English Mastiffs and Irish Wolfhounds. They were given the name “Englische Dogge (English dog)”, however, there was no formal breed for them.

The dogs were primarily used for hunting bear, boar, and deer, with the favourite ones staying at night in the bedchambers of their lords. When firearms become more prominent Englische Dogges become rare and were only kept as pets or as a hobby.

During the 19th century the name of these dogs was changed a number of times. It was known as the “Deutsche Dogge” in Germany and the “German boarhound” in English-speaking countries. The breed would later become known as the “Great Dane”, after the grand danois in Buffon’s Histoire naturelle, générale et particulière

Great Dane’s have a powerful and muscular body with a coat that can come in Fawn, Black, Brindle, Mantle, Blue, Grey, and Harlequin. Other colours are possible, but not acceptable for show dogs.

The breed also has natural floppy, triangular ears that, in the past, were commonly cropped to make injuries less likely during hunts. In the United States it is common to find Great Danes with cropped ears that stand up, however, in many other countries the practice is banned.

Great Danes are one of the largest breeds of dog with most weighing between 50 to 82 kg (110 to 180 lb). They can also be very tall with males usually standing 76 to 79 cm (30 to 31 inches), while females are typically 71 to 76 cm (28 to 30 inches). The tallest dog ever was a Great Dane called Zeus who measured 111.8 cm (44 inches) from paw to shoulder.

Dilated cardiomyopathy and many congenital heart diseases are also commonly found in the Great Dane. Additionally, they tend to suffer from bloat and can develop Wobbler disease, a problem that affects the vertebral column. Average lifespans tend to be 6 to 8 years.

Great Danes are usually a very friendly and gentle breed of dog, but they can become very fearful or aggressive if they are not socialised or trained properly.

• Male height – 76 to 79 cm (30 to 31 inches)
• Female height – 71 to 76 cm (28 to 30 inches)

Landseer (60 – 80 kg)

During the colonial times, large white and black “Newfoundland dogs” were brought to England because of their excellent swimming abilities. Fishermen used these dogs to tow nets to the shore and to save them or other fishermen from drowning.

Because of the breeds impressive appearance, many painters made them the subject of their work. The most famous of these paintings was created by renowned English animal painter Sir Edwin Landseer in 1838. Later the breed would be named after Sir Edwin Landseer.

Male Landseers are very big dogs with a bodyweight of 65 to 80 kg (143 to 176 lb), while females are slightly smaller at 60 to 75 kg (132 to 165 lb). Heights can range from 72 to 80 cm (28 to 31 inches) for males and 67 to 72 cm (26 to 28 inches) for females.

Newfoundland (55 – 80 kg)

This massive breed originated on Newfoundland and it is descended from a breed indigenous to the island known as the lesser Newfoundland, or the St. John’s dog. Newfoundlands around closely related to other Canadian retrievers such as the Labrador and Golden Retriever.

The Molosser-like appearance of the breed is a result of an introduction of Mastiff blood. It is believed that the Mastiffs introduced into the breed were either from Portugal or England.

Newfoundlands tend to be black, brown, grey, or white and black in colour. They have extremely large bones and a muscular body. Additionally, Newfoundlands have enormous lung capacity and webbed feet for swimming extremely long distances, and a thick, oily, waterproof double coat that protects them from the cold.

Male Newfoundlands tend to weigh anywhere from 65 to 80 kg (143 to 176 lb), while females are usually 55 to 65 kg (121 to 143 lb). the largest ever recorded Newfoundland was 120 kg (260 lb) and measured 1.8 m (6 ft) from tip to tail.

Leonberger (45 – 77 kg)

In the 1830s, Heinrich Essig, a dog breeder and mayor of the town of Leonberg in Germany, claimed to have created the Leonberger by crossing a Newfoundland with a Great St. Bernard Hospice and Monastery. Later, a Pyrenean Mountain Dog was added, which resulted in very large dogs with long, white coats.

The first dogs registered as Leonbergers were born in 1846 and they featured many of the prized qualities of the breeds from which they were derived. It was believed that only five Leonbergers survived the First World War and almost all were lost in the World Ware II as well. During both wars, Leonbergers were used to pull ammunition carts. Leonbergers today can be traced to eight dogs that survived the Second World War.

The breed features a water-resistant double coat and a large and muscular body. A striking black mask adorns the head and projects the breed’s distinct expression of intelligence, kindness and pride. A variety of colours are acceptable, including red-brown, yellow, sand, black and more. The nose, paw pads and lips should always be black

Male Leonbergers tend to weigh anywhere from 54 – 77 kg (120 – 170 lb), while females tend to usually weigh around 45 – 61 kg (100 – 135 lb). In terms of height Males are usually 71 – 80 cm (28 – 31 inches) and females can be 65 – 75 cm (26 – 30 inches).

Leonbergers are excellent family dogs and once socialised and trained they are self-assured, submissive to family members, friendly with children and insensitive to noise. They tend to be very intelligent, loyal dogs that are also playful. Proper training and socialisation is essential.

Overall, Leonbergers are strong, healthy dogs and don’t usually suffer from hip dysplasia (Many breeders screen their Leonbergers for the problem). However, while they tend to be quite healthy dogs, they have a short lifespan of around 7 – 8 years, around 4 years shorter than the average purebred dog.

Leonberger Stats

• Male weight – 54 to 77 kg (120 to 170 lb)
• Male height – 71 to 80 cm (28 to 31 inches)

Bernese Mountain Dog (40 to 75 kg)

Bernese Mountain Dogs are one of the four breeds of Sennenhund-type dogs from the Swiss Alps. They were bred from crosses of Mastiffs and guard-type breeds, and were brought to Switzerland by the Romans 2,000 years ago. However, despite the breeds ancient beginnings, it was only officially established in 1907.

The breed was originally used as an all-purpose farm dog for guarding property and to drive dairy cattle long distances from farms to alpine pastures They were also used to transport carts of milk and cheese, and as such, they were given the nickname “Cheese Dogs”.

Bernese Mountain Dogs have a highly muscular body with a very strong, wide back. The head of these dogs is flat on the top and they feature a distinctive tri-coloured coat that is black, white and rust in colour.

Males typically weigh between 45 to 75 kg (100 to 160 lb), while females are usually 40 to 65 kg (90 to 140 lb). Most males stand 64 to 70 cm (25 to 27.5 inches) in height, with females being 58 to 66 cm (23 to 26 inches).

Bernese Mountain Dogs can have quite a varied temperament, however, they should not be aggressive, anxious or shy. As they are outdoor dogs at heart, it is important to exercise them regularly. If they are not exercised correctly, Bernese Mountain Dogs can harass their owners or bark continuously.

Unfortunately, Bernese Mountain Dogs have a much higher rate of fatal cancer than most other breeds of dog. As such, they have quite a low life expectancy of around 7 to 8 years.

Bernese Mountain Dog Stats

• Male weight – 56 to 75 kg (100 to 160 lb)

One of the first descriptions of the breed comes from Fray Miguel Agustín’s book the Libro de los secretos de la agricultura, casa de campo y pastoral, which was published in 1617. The spread of the breed occurred in the 19th century with the first of them being introduced into the United States in 1824.

Pyrenean Mountain Dogs feature a weather-resistant double coat that consists of a long, flat, thick, outer coat and a fine, woolly undercoat. The main coat colour is white, but varying shades of grey, red, or tan are acceptable.

Neapolitan Mastiff (50 – 70 kg)

This massive breed of dog derives from the traditional guard dogs of Central Italy. Selective breeding began in 1947 by Piero Scanziani. He created the standard for the breed and it was officially recognised in Italy in 1949, while it would have to wait until 1956 for its international recognition.

The most prominent feature of Neapolitan Mastiffs is the abundant and loose skin around the neck and head (although they do have loose skin in other areas as well). Around the neck and head, the skin hangs in heavy wrinkles much like a Chinese Shar-Pei.

Neapolitan Mastiffs tend to have black, grey or leaden coats, however, other colours such as fawn, mahogany, hazelnut and more are accepted. White markings on the toes and chest are tolerated for this breed.

Males tend to weigh anywhere between 60 to 70 kg (130 to 155 lb), while females are usually smaller at 50 to 60 kg (110 to 130 lb). Heights can range from 65 to 75 cm (26 to 30 inches) for males and 60 to 68 cm (24 to 27 inches) for females.

Irish Wolfhound (48 – 70 kg)

The Irish Wolfhound is a historic breed of sighthound that originates from Ireland. The original Irish Wolfhound breed was presumed extinct by most knowledgeable experts but was recreated by Captain George A. Graham in the late 19th century.

It is believed that the original Wolfhound breed dates back to the Roman times and they were used for hunting. During the 1836 meeting of the Geological Society of Dublin, Dr. Scouler presented the “Notices of Animals which have disappeared from Ireland“, with the wolfdog mentioned.

Modern Irish Wolfhounds were created from the best examples of the Scottish Deerhound and the Great Dane, two breeds which are believed to have been derived from the original Wolfhound. It is also believed that some other breeds such as the Tibetan Mastiff were used to develop the modern Irish Wolfhound.

Irish Wolfhounds have a rough coat with a very muscular, strong build that somewhat resembles a Greyhound. They can come in a variety of colours including grey, red, black, fawn, and wheaten.

Male Irish Wolfhounds usually weigh between 54 to 70 kg (120 to 155 lb), while females are typically 48 to 61 kg (105 to 135 lb). They are considered to be the tallest dog breed in the world with males coming in at 81 to 86 cm (32 to 34 inches), while females are usually around 76 cm (30 inches).

This breed tends to be introverted and intelligent. They are considered to be poor guard dogs and will protect individuals instead of the owner’s house or possessions. Irish Wolfhounds are favoured for their loyalty, affection and patience, and they tend to be good with children.

Like many large breeds of dog, Wolfhounds have a relatively short lifespan of about 7 years. Dilated cardiomyopathy and bone cancer are the leading causes of death in this breed.

Due to their power and size, the breed has been put to work in many different capacities from pulling carts to guarding flocks and European castles.

The Dogue De Bordeaux features a well-balanced, muscular build. A massive head with proper proportions and features is an important trait of this breed. Compared to a breed like the English Mastiff, Dogue De Bordeaux are set somewhat low to the ground. The coat should be short and fine, with a soft to the touch feel. Colours tend to be fawn to mahogany with a black, brown, or red mask.

Kangal Shepherd Dog (41 – 66 kg)

The Kangal Shepherd Dog is a large breed that was originally created to serve the people of Anatolia. The breed has been in use for thousands of years, and despite its name, it is not a herding dog but rather a guardian. Kangal Shepherd’s often live with flocks of sheep and actively fend off predators of all sizes.

Compared to many other Mastiff breeds, the Kangal Shepherd Dog is not as heavy. This allows the breed to be much more agile and faster than other large dogs. Kangal Shepherds have a short and dense coat that is pale fawn or tan in colour, and all of them have a black facial mask with black or shaded ears.

In America, the standard for the breed is a weight of 50 to 66 kg (110 to 145 lb) for males and 41 to 54 kg (90 to 120 lb) for females. Heights range from 76 to 81 cm (30 to 32 inches) for males and 71 to 76 cm (28 to 30 inches) for females.

This breed tends to have a temperament that is calm, controlled, independent and protective. They can be aloof to strangers, but a well-socialised dog will be friendly with visitors and children. Kangal Shepherd Dogs are not recommended for inexperienced dog owners.

Anatolian Shepherd (40 – 65 kg)

This breed originates from Turkey and is named after the peninsula of Anatolia. Anatolian Shepherds are members of a very old breed of dog and are probably descended from the powerful hunting dogs of Mesopotamia.

They were developed over time to meet a specific set of circumstances. The most important of these was the ability to live in both very hot and very cold environments. Additionally, they had to be able to guard flocks moving great distances across the Central Anatolian Plateau. Today, they are still used to guard livestock and can be found in many parts in rural USA.

Male Anatolian Shepherds can be between 50 to 65 kg (110 to 143 lb), while females are typically smaller at 40 to 55 kg (88 to 121 lb). Heights are usually 74 to 81 cm (29 to 32 inches) for males and 71 to 79 cm (28 to 31 inches) for females.

As this breed was developed to be independent and forceful, they can be challenging to own as pets. It is vitally important that socialisation and firm training are undertaken at a young age. They tend to roam, so microchipping and tagging is highly recommended.

Like most breeds of dog, the primary cause of death in Anatolian Shepherds is cancer. They tend to live around 11 years on average, higher than most other breeds of similar size.

Akbash (34 to 63 kg)

This rare breed of dog originates from Turkey and goes by several other names such as the Coban Kopegi, Akbaş Çoban Köpeği, and Askbash Dog. The breed is primarily used as a livestock guardian or a shepherd dog.

Not much is known about the history of the breed, but it is thought that they were created about 3,000 years ago. Modern day versions of the breed were first introduced into the United States in the 1970s and they were officially recognised by the United Kennel Club in 1998.

The coats of this breed only come in white and as such, they blend in with flocks of sheep. Additionally, the coat is of the double variety and it is medium length.

Akbash dogs tend to weigh between 34 to 63 kg (75 to 140 lb) and stand 69 to 81 cm (27 to 32 inches) tall.

The Akbash breed is predisposed to some of the same health conditions that Mastiff-type breeds may also face. The most common health issues include hip dysplasia, hypothyroidism and gastric torsion (bloat).

Akbash dogs tend to be very protective of their family and they are fiercely loyal. They are intelligent dogs and if they sense anything amiss, they can growl or bark. A well trained and socialised Akbash should not be aggressive or shy.

Greater Swiss Mountain Dog (36 to 61 kg)

This large breed of dog was developed in the Swiss Alps and at one point it was believed to have been one of the most popular breeds in Switzerland. The exact origin of the Greater Swiss Mountain Dog is not known, however, the most popular theory on the creation of the breed is that it is descended from the Molosser.

The Molosser was a large, Mastiff-type dog, which accompanied the Roman Legions during their invasion of the alps more than 2,000 years ago. A second theory is that in 1100 BC, the Phoenicians brought a large breed of dog with them to settlements in Spain. These dogs later migrated eastward to the Swiss Alps.

It is believed that Greater Swiss Mountain Dogs almost died out in the 19th century but the breed was rediscovered in the early 1900s. Today, numbers of the Greater Swiss Mountain Dog have grown, but it remains a rare breed.

Males of the breed are usually 41 to 61 kg (90 to 135 lb) in weight, while females are typically 36 to 50 kg (80 to 110 lb). Heights range from 65 to 72 cm (25.5 to 28.5 inches) for males and 60 to 69 cm (23.5 to 27 inches) for females.

Greater Swiss Mountain Dogs tend to be very happy and enthusiastic, especially when they are around people or other dogs. While the breed does need exercise, they do not need a vast space to play in, unlike some other larger dogs.

For the most part, Greater Swiss Mountain Dogs are relatively healthy for their size and have far fewer health related problems than other breeds of similar size. Despite being healthy dogs, they still have a relatively short lifespan of about 8 to 11 years.

Black Russian Terrier (45 – 60 kg)

The Black Russian Terrier (BRT), also known as the Chornyi Terrier is a breed of dog that was created by the USSR in the late 1940s for use as military/working dogs. Breeds used in the development of the BRT largely came from countries where the Red Army was active during the Second World War. The main breeds that make up the BRT include the Giant Schnauzer, Airedale Terrier, Rottweiler, Newfoundland, and Caucasian Shepherd Dog.

BRTs were bred solely by the state-owned Red Star Kennel in Moscow until 1957, when some puppies were sold to civilian breeders. In time, the breed spread to other parts of the USSR and then to the rest of the world.

The breed has a double coat with a coarse outer guard hair over a softer undercoat. The coat is hard and dense, and it should b trimmed to between 5 and 15 cm (2 to 6 inches). A beard and eyebrows should form on the face, and there is usually a slight mane around the neck that is more pronounced on males.

Male BRTs should weigh between 50 and 60 kg (110 to 132 lb), while females should be 45 to 50 kg (99 to 110 lb). The height of the breed should be 72 to 76 cm (28 to 30 inches) for males and 68 to 72 cm (27 to 28 inches) for females.

This breed is typically calm, confident and courageous, however, some can be stubborn and lazy. They tend to be highly intelligent dogs that respond well to training. BRTs can be somewhat aloof with strangers, but are extremely friendly once they get to know a person.

Compared to many other large breeds of dog, BRTs have quite a long lifespan of 9 to 14 years. They are mostly healthy dogs, but suffer from hip dysplasia, elbow dysplasia and Hyperuricosuria

Komondor (40 – 60 kg)

The first written reference to the Komondor breed dates back to 1544, however, it is believed that the breed started much earlier. Komondors are descended from Tibetan dogs and came from Asia with the Cumans. The Cumans had to flee westwards when the Mongols began to expand their territories. Komondors are related to the South Russian Ovcharka, the Puli, the Old English Sheepdog and more.

With a long, thick, strikingly white coat, Komondors are a unique looking breed. Their coat features a soft undercoat and a coarser outer coat that combines to form tassels or cords. The coat is usually around 20 to 27 cm long and it is the heaviest in the canine world.

Male Komondors tend to weigh between 50 and 60 kg (110 to 132 lb), while females are usually 40 to 50 kg (88 to 110 lb). The average height of males is 80 cm (31.5 inches), with females being 65 cm (25.5 inches).

Cane Corso (40 to 50 kg)

This breed of dog comes from the South of Italy and is closely related to the Neapolitan Mastiff. They are descended from the old Roman Empire Molosser dogs and the name is derived from cane da corso, an old term for catch dogs used in rural activities for cattle and swine.

Cane Corsos were used to protect property, livestock and families, and some continue to be used for these purposes today. The breed become rarer in the 20th century when life changed for Southern Italian rural farms. In the late 1970s a group of enthusiasts began a program to bring the breed back from near extinction.

The most distinguishing feature of Cane Corsos is arguable the large and imposing head. They appear in two basic colours: black and fawn. Brindling of varying intensity is common on both coat colours and white markings are common on the chest, tips of toes, the chin, and the bride of the nose.

Male Cane Corsos tend to weigh between 45 and 50 kg (99 to 110 lb), while females are slightly smaller at 40 to 45 kg (88 to 99 lb). Heights range from 62 to 70 cm (24 to 28 inches) for males and 58 to 66 cm (23 to 26 inches) for females.

Cane Corso dogs are usually docile and affectionate to their owners. They can be easily trained, but very aggressive to strangers and difficult to handle for vets. The average lifespan of this breed is around 9 years with some colours living longer than others.

Scottish Deerhound (34 – 50 kg)

The Scottish Deerhound is not only one of the largest dogs in the world, it is also one of the fastest. It is a large breed of sighthound that was originally bred to hunt Red Deer by coursing.

Scottish Deerhounds are somewhat similar in appearance to a Greyhound but with a heavier build and longer, rough coat. The breed is closely related to the Irish Wolfhound and was a contributor to the breed when it was re-created at the end of the 19th century.

With the demise of the clan systems in Scotland, Deerhounds became sporting animals for landowners and the nobility. Due to their speed and silent hunting ability they are capable of making quick work of any game the size of a hare or larger.

Male Deerhounds are usually 76 – 81 cm (30 – 32 inches) in height while females are typically around 71 cm (28 inches). Weights for males can be anywhere from 39 – 50 kg (85 – 110 pounds), while females can be 34 – 43 kg (75 – 95 pounds).

This breed is known to be gentle and extremely friendly. They need considerable amounts of exercise when they are young to properly develop their health and condition. While they do not need considerable amounts of space to live in, apartment living is not recommended for these dogs.

Scottish Deerhounds tend to live around 8 to 9 years and they can suffer from cardiomyopathy, osteosarcoma, bloat, stomach or splenic torsion, and a variety of other health problems.

Dogo Argentino (35 – 45 kg)

The Dogo Argentino is a large, muscular breed of dog that was originally developed in Argentina for the purpose of big-game hunting. It was first bred in 1928 from the Cordoba dog, along with a number of other breeds, including the Great Dane.

Antonio Nores Martínez was the man behind the creation of the breed, and he wanted a dog that would exhibit steadfast bravery and an unwavering willingness to protect its owner. The breed is so determined and strong that they are known to take down mountain lions.

Dogo Argentinos have a short, white coat with black spots in its skin. The body is strong and muscular, and there are rarely any markings on the coat. The breed is often described as looking similar to the American Bulldog.

Males are usually 40 to 45 kg (88 to 99 lb), while females are typically 35 to 40 kg (77 to 88 lb). Heights range from 60 to 68 cm (24 to 27 inches) for males and 60 to 65 cm (24 to 26 inches).

Dogos are highly intelligent and courageous with a strong, natural instinct to protect their home and family. They are very social dogs, but they make a strong distinction between familiar people and strangers. This means it is very important that they are trained and socialised correctly.

As with Dalmatians, white Boxers, and white Bull Terriers, Dogos may experience pigment-related deafness. There is a possibility of around 10% deafness in Dogos, but this problem can be dramatically reduced with proper breeding.
