As more and more people enter the city, it is difficult for us to see dog mating scenes again.
However, many people should often see this kind of scene when they were young, especially for children in rural areas. Dogs usually use back-to-back postures when mating, and it looks like their tails are bonded together. If the dog is forcibly separated, it is likely that they will be injured. Why is this happening to
?
There are tens of millions of species on Earth. During the evolution process, different reproduction strategies will evolve due to different environments. The mating method, time, etc. are very different. Some are quick to fight and some are long-lasting.
For example, lions may only have a few seconds each time, but the number of matings will reach hundreds of times a day!
There are also those who pay the price of their lives to complete mating. For example, male bag shrew will look for females during estrus. When they find only one, they will start mating crazily, even if they don’t eat or drink. In this crazy state, male pouch shrews are likely to die!
. Dogs usually adopt a long-term mating reproduction strategy, which lasts for about 30 minutes and is difficult to separate during mating. This is the "knot lock phenomenon".
However, the environment of nature is very unsafe, and it is difficult for dogs to separate during mating. Once they encounter dangers, such as being attacked by large predators, the dogs are likely to die. So why are they still evolving this way of reproduction?
Simply put, this is the result of natural selection. This "knot locking phenomenon" is not only found in dogs, but most canine animals have it.
Indeed, long-term mating is likely to be captured by natural enemies, but if the mating time is too short, the chance of conception will decrease. In the animal world, there are usually no fixed partners. When the male wants to mate again, he may not be able to find a suitable female.
The reproduction of the animal kingdom is selfish and everyone hopes to inherit their own genes. Therefore, long-term mating can not only increase the conception rate, but also prevent females from being seized by other males, so that their offspring can be left behind.
At the same time, relatively speaking, the living environment of dogs is relatively safe, and long-term mating is in line with their reproductive strategies.
So, what happens if dogs are forced to separate them during back-to-back mating?
I believe many friends have done this kind of thing when they were young. Out of curiosity, when they see a mating dog, they will find ways to separate the two dogs, but they find it difficult to separate them. Why is this happening?
This is caused by the special physiological structure of dogs. When a dog is mating, a spherical structure on the male genital organs will expand rapidly, while the female genitals will contract, which will cause "knot locking" and make it difficult to separate.
At the same time, there is a bone in the male dog's genitals, which can ensure longer mating time, while human males lose this bone during evolution.
If the mating dog is forcibly separated, it is likely to cause injury to the dog and damage to the reproductive organs, and the consequences are very serious.
So, if you accidentally encounter a dog mate in your life, don’t disturb them, let alone force them to separate them!
