It is said that China Pastoral Dog is the dog with the lowest IQ. Why?

Let me analyze it from an objective point of view: first of all, you said that the IQ ranking of dogs is ranked by foreigners according to their preferences, which is not true. As far as I know, dog IQ rankings are published by dog researchers in more than 60 different countries after years of research. In terms of accuracy, we can see that. Of course, I mean the ability to train beginners. Border herders, including your schnauzer, should learn things quickly. And you are right to say that you didn't consider the overall situation, because there are only 80 or 90 dog breeds participating in the ranking, and there will be many omissions, and it is certain that there is absolutely no China garden dog, so others say that China garden dog has a low IQ, either out of context or according to their own feelings and preferences, and there is no scientific basis. By the way, my family can recite the animal husbandry training 30-50 times, so as long as you look at my family, the IQ ranking of shepherd dogs should be between 30-60, at least much smarter than myna and Beijing Terrier. At the same time, it is useless to say that a garden dog is familiar with people's wishes, especially those living in rural areas should be deeply touched. Second, it's a little hard to say. Police dogs in China, such as Kunming dogs, are indeed China breeds. However, there are breeds of dogs that are generally no longer called local dogs, and it is reasonable to be reluctant. But the police dogs in China are mainly German shepherds, so the comparison is still the same. . . Trouble, and sometimes, in the army, in order to get better dogs, they will cross, just like Golden Retriever and Labrador cross better guide dogs. Therefore, police dogs in China have something to do with foreign dogs, and there is no comparability. Third, your last point, IQ is related to training. I can only say that the general IQ is still the same, and it is difficult to change. Unless someone has been training a breed of dogs for generations, it may strengthen the heritability of memory and increase IQ. In short, it is difficult to have other methods, and the ranking is still relatively reliable. By the way, many so-called local dogs are not pure enough, and they are all hybrids. Of course, what kind of purebred China garden dog is still inconclusive, but the overall outline is a medium-sized dog with (temporary) random coat color, curly tail and brown eyes. As for the ear, standing ear or hanging ear is still controversial and uncertain. So, with all due respect, there is only one local dog in your house. It may be impure. In short, the garden dog is quite clever, we firmly believe!
