If there is no redness, swelling or pustules, the breeder can use scissors to cut them short by themselves; if there is redness, swelling or pus, the owner should pay attention and purchase disinfectant and anti-inflammatory drugs, apply them daily and treat the puppy. Some breeds of dogs undergo tail docking surgery at birth. Tail docking can protect the dog from injury, prolong the dog's life, and have a good appearance.
