You wont believe the size of the world’s largest dog breeds! Though there is no universal height or weight at which a dog breed is officially classified as a big dog, some groups define giant dog breeds as those heavier than 100 pounds (45 kg). The heaviest dog ever recorded was a St. Bernard named Benedictine who weighed 366 pounds (166 kg)! But despite their threatening body proportions, most of the biggest dog breeds make excellent family pets. If you are thinking about owning a big dog, take a look at 25 of the world’s largest dog breeds found in today’s list.
Originally bred by nomadic cultures of Tibet, China, Nepal, and Central Asia, the Tibetan mastiff is an ancient breed of a large, muscular dog with thick, usually dark coat. Its name is misleading though – it’s not a mastiff. A better name for the dog would be Tibetan mountain dog. Males can reach heights of up to 83 cm (33 inches) and weigh between 45–72 kg (100-160 pounds) but overweighed dogs are quite common. As a flock guardian dog in Tibet, it is capable of confronting predators the size of wolves and leopards.
Developed in Argentina primarily for the purpose of big-game hunting, Dogo Argentino is a huge, muscular dog with a white, very short coat. Males can grow up to 30 inches (76 cm) long and weigh over 120 pounds (55 kg).
Greater Swiss mountain
The Greater Swiss mountain dog is another large dog breed which was developed in the Swiss Alps. This big dog is robust and heavy-boned with great physical strength but is still agile enough to perform the all-purpose farm duties it was originally used for. Among all the Swiss mountain dogs, this breed is considered the oldest and largest with males often weighing well over 150 pounds (72 kg) and reaching heights of almost 30 inches (76 cm). The Greater Swiss is a happy, intelligent and sociable dog with an enthusiastic nature and a strong affinity to people and children.
Also known as Pakistani Mastiff, the Bully Kutta is a descendant of the extinct Alaunt, an ancient dog breed that originated in present day Pakistan. The Bully Kutta is predominantly white in color. However, fawn, brindle, brown, black and various bi-colors are also common. These extra large dogs are usually about 35 inches (90 cm) tall and can weigh as much as 210 pounds (95 kg). The breed is generally docile, friendly, and very trainable.
Dogue de Bordeaux
Also referred to as Bordeaux mastiff or French mastiff, the Dogue de Bordeaux is one of the most ancient French dog breeds. It is a very powerful and muscular dog that has been put to work in many different capacities, from pulling carts and hauling heavy objects, to guarding flocks and even the castles of the European elite. Dogue de Bordeaux is not as tall as some other breeds on this list but is massive with a powerful build with males weighing in well over 150 pounds (68 kg). One of the distinctive features of the breed is a wide, massive head, claimed to be the largest head in the canine world, in proportion to the rest of the body. Unfortunately, these dogs are prone to numerous diseases and their average lifespan is one of the shortest among all breeds, usually ranging around 5 to 6 years.
