There is no saying that white-tailed dogs cannot be raised. This is superstitious. Dogs with white tails are mostly due to genetic inheritance. For example, Samoyed, Bichon Frize, Scottish Shepherd, etc. all have white tails. They are not only bred by many people, but also very popular with the public. Dogs are friends of humans. When choosing to raise a dog, Be responsible and don't abandon your dog because of all kinds of nonsense.
