The largest breed of dog in the world is the Caucasian dog. Although they are as old as the Tibetan mastiff, the popularity of the Caucasian dog is higher in the world. This is because during World War II, the Soviet Union used 126 Caucasian dogs to tie up bombs and blew up more than 300 tanks of the enemy. Since then, the Caucasian dog became famous in the first World War and became a "national treasure" of the Soviet Union.
However, the Caucasian dog is only the largest dog on average. According to the current records, the largest known dog is a great dane named "big George" from Arizona, USA. its height has reached 2.2 meters, and its weight has reached 111 kg, which is much larger than the largest known Caucasian dog. Therefore, the largest dog in the world is, strictly speaking, big George.
After watching the largest dog, let's take a look at the smallest tiger? The word "breed" is only suitable for animals domesticated by humans. Take dogs for example. There are at least 100 kinds of dogs. These are species. They are not biological "species". Biologically, all dogs in the world are domestic dogs, and domestic dogs are one of the subspecies of gray wolf.
The tiger is different. It has not been domesticated, so there are only species and subspecies, and there is no variety. Among them, tiger is the species name of all tigers. As for South China tiger, northeast tiger, Bengal tiger and so on, they are subspecies of tiger. The original tiger has 9 subspecies, of which Bali tiger is the smallest. Their average length is only about 1.2 meters and weight is about 100 kg.
However, it is a pity that the Bali tiger was killed by humans as early as 1937.
There are 6 existing tiger subspecies, of which South China tiger has been extinct in the wild, and the smallest existing tiger subspecies is Sumatra tiger, which is only distributed on Sumatra island in Indonesia. It is also the most endangered tiger subspecies. The wild number is less than 400, and it is an extremely dangerous species.
The size of Sumatran tiger is relatively small. The average weight of adult females is only about 90 kg, the average weight of males is about 120 kg, and the comprehensive average weight is about 105 kg, which is nearly twice as small as the existing largest tiger subspecies northeast tiger.
Can the biggest Great Dane beat the Sumatran tiger? In general, the body shape of predators is an important reference standard for winning or losing. From the comparison between the body shape of the Great Dane and the Sumatran tiger, the Great Dane is a little larger than the female Sumatran tiger and smaller than the male. Therefore, we won't compare the male Sumatran tiger with the Great Dane dog, because even the female can't beat the Great Dane dog. Why? Let's talk about it from the following three aspects:
First: body shape.
Although the largest Dane weighs 111 kg, we should not only look at the weight data, but also look at its actual body shape. The Great Dane is a kind of dog with long limbs and body, which is also the reason why it is tall. However, with a height of more than 2 meters and only 111 kilograms, the Great Dane is doomed to be thin.
It is precisely because of the thin body shape of the Great Dane that it is easy to suffer from bone diseases, resulting in their average life expectancy being much lower than that of most dogs (less than 10 years).
However, Sumatran tigers are different. They are well proportioned, with developed and strong limbs. Although they are the smallest tigers, they still have strong explosive power. From this point of view, the Great Dane is a bit weak.
Second: combat effectiveness comparison
The fighting power of carnivores is mainly reflected in "weapons", that is, claws and mouths. In terms of the diversity of weapons, the Great Dane is much worse than the Sumatran tiger, because the claws of canine animals can not be retracted, which leads to their claws are very blunt and can hardly be used as weapons.
However, tigers are different. Their claws are retracted into the claw sheath when they are not in use, which protects the sharpness of the claws. In actual combat, in addition to the slapping of the tiger's paw, the 5 cm long claw can also cause serious trauma to the other party.
As for the mouth, it is the length of canine teeth and the bite force. In terms of the length of canine teeth, the average length of Sumatran tiger's canine teeth is about 5cm, while the average length of Great Dane dog's canine teeth is only about 2cm. In this way, it is obvious that Sumatran tiger with longer and coarser canine teeth will cause more fatal damage when the other side takes a breath.
Compared with the bite force, the Great Dane has no eyes. The bite force of ronaway, one of the dog breeds with the strongest bite force in the dog industry, is only about 75 kg, which is considered as the ceiling level. Obviously, the skull of the Great Dane is not as thick as that of ronaway, so the bite force is smaller. (the figure below shows Rowena who kills bitdogs with combat power and bite force)
Although the Sumatran tiger is the smallest tiger, its bite force is still as high as 700-1000 pounds (about 317-453 kilograms), which is at least four times that of the Great Dane. With such a big difference in bite force, the result of their biting each other is that the tiger has the most skin injuries, while the dog's bones can be bitten through.
Although the Sumatran tiger and the Great Dane dog have no chance to meet, we can use two kinds of canine and feline animals to make an analogy, because the wild wolf is the ancestor of the dog, and its wildness and combat effectiveness are better than the dogs of the same level. In the nalipoki forest of Belarus, there is a cat with a body size such as the wolf, which can not only kill the wolf alone, but also drive the wolf away from its original habitat. It is the lynx.
The lynx is equivalent to a female Sumatran tiger, and the Great Dane is equivalent to a wolf. Since the lynx is killed by a wolf that is very wild and has a body advantage over itself, there is no problem for the Sumatran tiger to kill a larger dog.
To sum up, the largest known dog in the world is a Great Dane. Its weight has reached 111 kg. Although it is a ceiling level dog in the dog industry, it can at most deter the dog. In the face of wild tigers, even female Sumatran tigers will not have the slightest fear. Moreover, in the face of the Great Dane, Sumatran tigers can end the battle in less than 1 minute.
However, considering that the Sumatran tiger eats more than ten kilograms of meat at a time, the only chance for the Great Dane dog to win is to kill the tiger with more than 100 kilograms of meat.
