Now as long as we talk about canines, there will not be much expectation for their combat strength, after all, compared with the current cats, the canine family is relatively poor, the strength can be hard with the big cats, there is only the North American gray wolf, after all, other canines are not small or domesticated, whether in terms of strength or fierceness, they are not in the same grade as cats. But if the paleontology is also involved in the comparison, then the canine family will grow in an instant.
The largest canid on Earth is now the North American gray wolf, but if we move the time forward, 7 million years ago, a huge fierce dog occupied the position of the king of the beasts of North America, becoming a nightmare for local wildlife, and this canine is the Headney Upper Dog. From the name we can probably know what kind of existence this is, "on the dog", as the name suggests is the meaning of the dog, whether in terms of size or strength, this animal is indeed above the dog.
In fact, the size of the upper dog has also been growing with time, since entering the Pliocene, after millions of years of changes, finally appeared the largest Hideney upper dog, their strength crushed the canine family at that time, resulting in the instant decline of the canine bear family, and this animal also flourished rapidly in North America. However, in the subsequent history, the upper dog and other subfamily of dogs in the long biological evolution, due to the inability to adapt to the environment, gradually disappeared, and were eventually replaced by today's organisms.
The Hidney dog is huge, and their average weight can reach about 95-120 kg, which is equivalent to today's Sumatran tiger. However, in this period, among the felines, it is not as it is now, it is worth mentioning that the pasteur tiger in the contemporaneous cat family also evolved to the largest size - the Frick's pasteur tiger, which weighed similar to today's lions, with canine teeth up to 21 centimeters, and was the biggest competitor of the Hidney dog.
The huge size of the Hideney dog, coupled with the power of terror, allowed them to dominate North America at that time, they were like today's canines, they were social, hunting together, living together, the main food was the huge ancient camel, in the hunting style, may be a little different from today's canines, they are more inclined to kill directly, rather than saying first observe, and then lurk forward. Instead, just like Mount Tarzan pressing the top, the whole army rushed down directly from a high place, and the scene was very spectacular, scaring the animals half to death.
Tigers and wolves have clashed since ancient times, and today is no exception, such as the Siberian tiger and the Siberian wolf, there are often conflicts, but now the number of wolves and tigers is very rare, the probability of them being able to meet is greatly reduced, so there are very few such incidents. Millions of years ago, that wasn't the case. Breeds such as the local Babo saber-toothed tiger often meet with the Hedney dog, and the two are strongly competitive, and they will naturally fight.
However, unlike today's tiger-wolf battle, at that time, due to the huge size of the Hedney dog, it was superior in number, after all, the saber-toothed tiger was also a solitary animal, so when fighting, it was often the upper dog that had the upper hand, and the saber-toothed tiger often lost. But in the long process of biological evolution, neither animal escaped the survival of the fittest in nature, they were gradually replaced by stronger and larger beasts, and the canine family also evolved, eventually forming the North American gray wolf we see today.
