Umbilical hernia in dogs is generally caused by the umbilical hole not being properly ligated after birth, genetic factors, or external factors. Some dogs can heal themselves or become smaller during growth and development, but some dogs cannot. Self-healing requires surgery, otherwise it will cause pain to the dog and affect the dog's normal life.
Tips:
If you find that your dog’s belly button is bulging, it is best to take your dog to the pet hospital for examination. Also avoid strenuous exercise for your dog.
