When choosing a dog, you need to look at the color of the dog. One yellow and two black, three flowers and four white. It means that yellow dogs are the best, black dogs are second, and flower dogs are the third, and white dogs are considered the least good. The black dog, whose folk customs are widely circulated, has an unusual working ability and can bypass unhappy things.

Spring dogs are born with smelly bodies, summer dogs often attract stinky cockroaches, autumn dogs bark blindly at night, "Winter dogs are born with the smallest elf." In other words, dogs born in the coldest days are more aura. Many people think that the autumn pregnancy dog is the best to be born in winter.

One dragon, two tigers and three leopards are the beard on the dog's jaw. If one is so good, two are also very good. Three are the little leopards, and the little leopards have the habit of stealing food. Therefore, you cannot buy 3 beards for local dogs.

Dogs with deep eyes can identify the relationship between people and people. Dogs with protruding eyes usually have myopia and don’t even recognize their owners when they go home, and they will keep barking at their owners. The heavier the dog's eyes, the better.

Local dogs generally have two kinds of small tails. One is rolled upwards, called the tail of money, which is said to be prosperous. Another type of sheepdog that is standing up toward the sky is called "gun tail" which is a sign of a good sheepdog.
