Dog tail docking is when people cut off the dog's tail through surgery, so dog tail docking occurs. There are many methods of tail docking surgery, but the most common method is to use sterilized thin thread to tie the tail below the part that needs to be cut off when the puppies are just a few weeks old. In this way, blood circulation is hindered, and after a few weeks, the tissue that needs to be cut off will become necrotic and fall off naturally. Therefore, there will be no bleeding during this process, and the newborn puppies' nerves are not fully developed, so they will not endure much pain. (Variety)
