Why is dog used to describe bad in traditional culture?

Because in ancient times, China has not been a dog as a pet breeding habits, in fact, this is also considered a recent habit, let's say that in ancient times the average rural family, even can not afford to keep a dog, even if the dog is used to watch the role of the door, but in the kind of their own food and drink are a problem, how can they also afford to raise a? Watchdog?

And those who are a little rich and noble family, their home to raise the dog is not used as a pet, raised to slip, are ? The dog is a watchdog. And this kind of dog's defense can be who, naturally is lower than these rich people to some class of people, and usually these dogs will be raised majestically, which leads to the poor, people for these dogs even worse.

Relatively speaking, horses, cows and goats are more popular with the public.

Mainly because our country in ancient times is mainly farming, these animals, then, relatively speaking, more useful, but also more valuable, some will not become their own extra burden, so you can see in the Chinese culture, the image of the horse cattle and sheep is very positive.

And the positive image of the dog, a good partner of mankind, loyalty, etc. This is in fact from the Western side of a cultural thought, because the Western fishing and hunting situation is more, in the pursuit of prey, have a good dog is very important, can make hunting twice as easy. That's why in the West, the idea that a dog is a good companion for people is a bit more advanced than in the East.

Again, in ancient China, the rich people they keep pets, most of them are mainly elegant, fish and birds are mainly more, and then do not help to raise a few crickets and grasshoppers fight a bit, the women's words to raise a cat there are a few, raise a dog is really only a handful of a vulgar and elegant literati holding a big dog in the street slipped the scene does not quite meet his image. The fact that you are carrying a bird or a box with crickets is much more sophisticated.

So ah, the ancient not love the dog is justifiable, but in the rural areas now, the dog can be said to have a family.
