The puppy is black all over and its four paws are white. What's the matter or is there a sign?

They are superstitious, saying that such dogs are not good, and they are Dai Xiao dogs. Because at that time, only doctors and people who carried the dead would wear white gloves, and the white paws of dogs seemed to wear white gloves. Also, if dogs bark, the old people can't say it well. They are all superstitious, as long as dogs like it. In this way, if I have a husky, it will only howl, not bark.
