An umbilical hernia is a condition in which abdominal contents protrude through the abdominal wall at the area of the umbilicus. An umbilical hernia is an opening in the muscle wall where the umbilicus (belly button) is located. The hernia allows the abdominal contents to pass through the opening.
There are two types of umbilical hernia, one is complicated and the other is uncomplicated. Complicated hernia is the condition in which contents of the abdominal cavity, such as loop of intestine, have passed through the opening and become entraped.
Soft swelling in the umbilical area is associated with uncomplicated hernia. This variable swelling can come and go. Aside from swelling, the dog otherwise appears healthy.
Symptoms seen with a complicated umbilical hernia may include:
Pain and warmth, especially at the site of the umbilical swelling
Vomiting
Lack of appetite
Depression
