this is my dog with Umbilical Hernia, she has had this since birth. She is 13.5 years old here and we went to the vet and we got more information about Umbilical Hernia.
An Umbilical Hernia occurs when the abdominal muscles fail to grow together and properly close the abdominal opening where the naval cord was attached at birth. The hernia usually appears as a soft swelling at the “umbilicus” or belly button.
Your veterinarian should evaluate all hernias. Mild hernias will contain a small amount of abdominal fat. If the hernia is large enough to allow a loop of intestine to become entrapped within it, strangulation of the intestine may occur. This is an emergency situation.
Diagnosis is based on symptoms and examination findings. Hernias should be repaired when the pet is spayed or neutered unless the defect is large enough to warrant immediate repair. Spaying or neutering of pets with umbilical hernias is recommended due to the potential for hereditary predisposition.
