The hands were soft to the touch, and the owner gave some anti-inflammatory drugs, which will slowly subside; 2. If the dog gets angry, it will cause lymph node enlargement. If the owner feeds some anti-inflammatory drugs, it will slowly subside; 3. It may also be a cyst, which needs to be sent to the doctor for treatment.
